1992 - 00 GM 4WD K Truck Upper & Lower Ball Joints Replacement w/ Upper Bushings Repair (Chevy GMC)

Рет қаралды 190,588

Күн бұрын

We do an EPIC and fully detailed disassembly repair and rebuild of the upper control arm with new genuine GM bushings and ball joints as well as replacing the forged lower control arm ball joints. This video is specific to GM old body style (OBS) 8-lug 4WD K trucks (Suburban Cheyenne Silverado Sierra) such as the K2500 and K3500 or the K1500 with 6.5L diesel engine option. GM part numbers and factory service manual torque values are provided along with special tools and techniques required.
The video shows the procedure performed on the drivers side of a 1998 Chevrolet Cheyenne K2500. Most 4x4 8 lug vehicles across the years covered should be very similar if still using the original GM factory suspension on OBS 1992 1993 1994 1995 1996 1997 1998 1999 2000 Chevrolet GMC and Holden vehicles like the Silverado Sierra Blazer Cheyenne and Suburban. This is a very long and detailed video with something for everyone doing one or all of these three component (UBJ, LBJ, UCAB) repair procedures including:
- Removal and reinstallation of the front disc brake caliper assembly
- Removal and reinstallation of the steering knuckle spindle rotor hub speed sensor assembly
- Removal and replacement of the pressed in lower ball joint and fasteners using a ball joint press
- Removal and reinstallation of the upper control arm assembly and temporary wheel alignment
- Removal and replacement of the upper control arm bushings
- Removal and replacement of the riveted upper ball joint and fasteners
- Removal and reinstallation of the control arm dust shield
WARNING: Wear appropriate vision and hearing safety equipment when performing these procedures, and make use of jack stands AND jacks during disassembly and assembly.

Thanks, this vid solved a mystery for me. I took apart my 97 k3500 almost a year ago, pulled the ball joints, and bead blasted and painted all the arms. Now I'm trying to put it together and don't remember how it came apart. I could not get the upper ball joints to fit. A Haynes manual and even a factory service manual showed the ball joint going on top of the arm. There was no way that would work on my truck. I remounted a joint on the underside of the arm for a test and it suddenly worked. Yours has it on the underside, so I'm confident that is the right way for mine too. For some reason they go both ways and even the factory service manual doesn't mention it.

@DrShock 7 ай бұрын

Thanks, the upper ball joint placement does vary between 1500 and 2500/3500 chassis types for GMT400 class trucks. The GM service manual does point this out, but only in the text as a passing comment. The only illustration provided by GM in the manual is for the 1500 orientation so alot of folks miss that detail.

Just did this on my ‘94 4x4 and wish I had seen this video first. Not sure why it didn’t show up in my you tube search. My only advice would be to forget about drilling and chiseling and pounding the upper control arm ball joint and bushings and just buy the entire upper A arm (that includes the ball joint and control arm bushings already installed). Only about $120 and you save two to three hours of drilling and chiseling and pressing out and in the bushings and you’ve saved the cost of the ball joint and control arm bushings. The lower control arm is another story because those are not as readily available. Good video though!

Yes, it does matter. I likely mentioned this in passing elsewhere in the video, but 1500 trucks are on the only ones mounted on top like that drawing shows. The 2500/3500 trucks (which this video is about) are mounted on the bottom (as you see in the videos thumnail photo e.g.). In all cases, what I was quoting at that time index from the service manual was that the bolts go head facing road, nuts facing sky.

And I don’t know “yet” if you have another video of you working on the lower A arm bushings or not. But, I also need to get those replaced as well as everything you shared in this video, sir. I so appreciate all of the information, part number’s (GM, &. other). Getting back to the lower A arm bushings, I was told that the (Don’t quote me on this term ) stabilizer arms had to come off, and the “keys” (???) has to be taken out, for those stabilizer arms to come off. In order to take out the lower control arm out. Does all of this sound correct to you ? I’d appreciate any any all information you might have on this sir.

@DrShock 3 жыл бұрын

Thanks, comment is much appreciated. I am doing a lower control arm video very soon. This particular vehicle just didn't need it though. When you do the lowers there's a need to relieve the torsion bar tension with a special compression tool and remove the bar assembly yes. Then you have to do bushings for either forged or stamped arms (similar to the lower ball joints I go over in this video the parts are different for each arm design).

Most automotive shops are hacks & do it as quick as possible. I would not trust them on drilling out the rivets. I have aircraft rivet guns & bucking bars. You can punch out the rivets shanks using a punch set with the rivet gun once u drill the head off. Aircraft rivet guns have slower harder hits then air hammers. Using a 4x or larger if available. Also back it up the rivet gun with a heavy bucking bar next to the rivet tail on the opposite side. If u put back the original rivets don't try using a air hammer it will work harden the rivets before there bucked. I recommend a 6x rivet gun & heaviest bucking bar u can find. You did a great job.

Where exactly did you put the jack stands and jack up point? Great video.

@DrShock 10 ай бұрын

Thanks. Your jack stand point is the standard jack point area on the frame rail, just like when jacking up in changing a front tire. But you'll want to keep your floor jack under the lower control arm as I showed. The main reason is that if the stabilizer link is rusted thru, there's nothing else preventing the torsion bar on a 4WD vehicle from flipping that arm down (can be a nasty surprise). If the link is intact, it will hold it the arm up and you can use the jack as necessary to help with getting the lower ball joint separated instead.

Another question: On a 1996, K2500, 8600 GVW, are the inner and outer tie rod ends the same on both sides? Rock Auto does not list the number per vehicle in the parts listings. For example, I purchase 4 front anti roll bar/sway bar bushings as it was listed as "bushing" not "bushings" so the one box had the two I needed, but I ended up with four as I ordered "2" bushings (which meant 4). Thanks is advance!

More leverage, breaker bar with the exact six point impact rated socket to make the best contact and have the highest strength. I've had to put steel pipes on those breaker bars for more extension/leverage (around 3ft) on some trucks as well. You can bungie the socket end to hold it where it needs to be if it has to get that long. After you get the bolts all out, replace any that have marred heads or corrosion with genuine GM ones.

How much good does that dust cover even do if you mostly drive on the road. On my 97 c1500 with 280k it's about gone but a bit hanging on. And here's a question. I'm watching because I think my ball joints are ok but I need new dust covers. So want to know how to take these apart to be able to replace them. Can you just take one lose at a time, replace it's dust cover, then do the other, then put everything back together? I'm guessing I'll have to take the shock lose to get the upper and lower are to move separately.(maybe not just saw the top get unbolted and it dropped down pretty far!)

@DrShock 3 жыл бұрын

Those rubber dust boots on tie rods and ball joints serve a similar purpose, to keep road dirt/grit and water out of the joint. Either will take the joint down in a short while, just like with a busted rubber CV axle boot. To replace them you would do all the same work in the video except you can skip the parts about removing the joints and upper control arm. Remember on K trucks the torsion bar takes the place of the front spring, so before removing the lower ball joint nut have a jack under there like I did. All that will hold it together is either the jack, or the sway bar link if it's still intact. Also those ball joint dust boots are not universal. They typically have to be from the same manufacturer as the joint to fit properly.

Where the upper control arm eccentric bolts go through I have seen that the brackets have a metal piece that can be punched out which turns the hole for the bolt into an oblong slot allowing for more camber adjustment. In your opinion would that be beneficial or can the alignment be done adequately with just using the existing hole that is there?

@DrShock Жыл бұрын

Most GM trucks of this era would have had the factory camber knock outs done very early in their life, around the second tire replacement. Its required to stay in front end spec once the wear sets in so I would suspect very few are still intact.

You could certainly go that route, and it can make for some extra working space. But when working on these old trucks though you have to weigh the risk of creating new problems. This truck had the original shafts in there from 1998, they were not leaking despite the age of the seals and I choose to leave them alone as much as possible to keep it that way. Sometimes they can get quite bonded in place after multiple decades as well. We were only in here to swap out the ball joints and upper bushings afterall. ;-)

On my 94, the upper ball is mounted at the top of A arm. Here it is below.

@DrShock Жыл бұрын

Yep, I explained this in the video with the GM service manual overview. Trucks that are 1/2 ton have to have the ball joint mounted differently than for 3/4 and 1 ton trucks. The truck shown in the vid is a 3/4 (K2500) truck. As long as the ball joint was riveted on, you know it was done the factory way. If it's bolted on, you cannot trust that it was not installed incorrectly by someone uninformed, so use the service manual guidance to correct past mistakes.

How come you didn't replace the stabilizer spacer

@DrShock 10 ай бұрын

I presume you're referring to the stabilizer bar link. And if so that's because it wasn't worn or due for any scheduled service. We don't incur unnecessary additional costs by firing a _parts cannon_ here. Only replace the parts that are confirmed defective, obviously worn, excessively corroded, or otherwise due for regularly scheduled mileage service per the GM service manual. A stabilizer bar link has no scheduled maintenance interval and is straightforward to replace separately, at a later time when it's actually necessary.

All of the pictures in the manual show the 'plate' of the upper ball joint is at the top of the control arm while in yours is at the bottom originally. How so? Is it because it's a K2500 and the manual is for K1500? I've got a K1500 and the plate is at the top like in the manual.

@DrShock Жыл бұрын

That's right, I go over this verbally in the video. 1/2 ton trucks mount the joint differently than 3/4 and 1 ton trucks. The illustration in the manual just shows the 1/2 ton. This is also an obvious difference when viewing the orientation of where the joint was originally factory riveted onto the control arm.

The video shows the forged steel version, it's thick heavy metal and typically found on 2500 or higher only. The stamped steel version will be thin metal, having a folded or shaped over arm design hollow underneath it (you can't miss it as it will be totally different appearance than the forged one in the video).

@BusyFingers 3 жыл бұрын

DrShock Thank you. I’m enjoying your videos tremendously. My question was the same; how to accurately ID forged vs. stamped lower control arms to purchase the correct replacement ball joint. I have a ‘98 K1500 and I am leaning toward the stamped version. Snow’s arrived up here in Canada, luckily my truck came from Florida, not too much rust!

@DrShock 3 жыл бұрын

@@BusyFingers The best answer I could give would be to take note of the forged arms in this video, they are of a solid _iron_ look and feel. No welding at all in the construction, solid one piece forged. No formed or shaped by stamping metal anywhere. Also note the forged design has a _narrow_ roundish solid metal on one side of the triangle whereas the stamped ones are flat and broad on both sides of the arm. So if your lowers do not look exactly like the ones in this video, they are very likely of the stamped steel version presuming they are original GM ones. They take different lower ball joints because the stamped one actually has the ball joint mount _welded_ on and its of a different design than the forged mount.

@BusyFingers 3 жыл бұрын

@@DrShock Yes, I see it clearly now. Had a look at mine and the upper contour of the lower control arm has a flanged top edge, curving down. Also, as you mentioned, there is a separation between the control arm and the ball joint mount itself, which must be welded on. These are the stamped version. I don't imagine there is an RPO code specific to lower control arms...probably not. Thanks to you again for the excellent advice.

@DrShock 3 жыл бұрын

Originally in the 90s and early 2000s the upper arms wouldn't have been replaced unless bent/damaged in an accident or due to deep corrosion concerns. The GM service manual walked mechanics thru drilling out the factory riveted ones as we saw in this video. The flood of inexpensive automotive parts imported from asia in recent years has changed _some_ of that approach. You can often buy a fully ready to bolt on upper control arm _with_ the ball joint _and_ the bushings for less than the OEM GM upper ball joint alone. But you have to shop around, most of those aftermarket upper arm assemblies are just a notch above scrap metal in quality. Maybe a MooG (though they are not what they used to be imo), or an ACDelco (just for the warranty). But I wouldn't consider the other uncommon brands. The phrase _you get what you pay for_ often applies to them. ;-)

Have also been thinking about some ratcheting combonation wrenches, but I whish folks would make them as 2 box ends with different sizes on each end so I'd need to buy fewer and a plain hex not the funky ones they claim work on rounded nuts, but to me don't seem to work well on any!.

@DrShock 3 жыл бұрын

I've had this Craftsman impact wrench for a few years now, long enough for them to have discontinued it. I haven't used my air wrenches or drills since I got it. The electrics have definitely reached the torque and battery life point that air is only useful still for hammers/chisels and paint guns imo. Now that's a light duty/DIY statement. A professional shop will still find air better due to battery limitations imo. When this Craftsman goes, I'll replace it with a Milwaukee. On the box end wrenches, yeah I've gradually collected ratchet versions of all the popular metric sizes now. And in some cases I've found a need to get the stubbies of same for those limited working room fasteners. But there are still situations where a non-ratcheting box end wrench is perfectly fine just like breaker bars are not rendered extinct by ratchet wrenches.

If you do the top ball joints, just buy the whole arm and assembly. If not, then the only way to do the rivets is to center punch the rivets head then use to step drill out. If you grind the heads you’ll lose the ability to find center and plum.

@DrShock 3 жыл бұрын

The aftermarket complete top assemblies are cheaper, but I prefer rebuilding the upper control arms with genuine GM parts instead just like back in the dealership days. There are a number of ways of approaching the rivet removal after two plus decades, thanks for sharing yours. Manually punching out the rivets after removing their heads is the GM service manual approach, but it's often unsuccessful after so much aging. So I prefer the approach of prying the rivets out instead. Here I'm only resorting to drilling in order to partially weaken the rivets outer diameter, so removing the rivet head is visually helpful.

@bradybell6129 3 жыл бұрын

Just a comment on your "ghetto" method of torqueing the nut. If you put the torque wrench in line with the wrench, you are increasing the length of the moment arm, so you should reduce the setting on the torque wrench. For example, if the wrench and the torque wrench are the same length, you should halve the setting.

@DrShock 3 жыл бұрын

Yep, there will be a _somewhat_ over specification torque situation resulting with the _inline_ improvisation I showed. As you highlight, this is because by lengthening the wrench the built in torque setting mechanism inside the wrench is no longer accurate for the force being applied. If the improvised extension could have been done at 90 degrees instead though, then this concern would not be applicable as the overall length of the wrench would be unchanged. One formula to calculate this, for those curious about precision, is to take the length of your torque wrench and multiply it by the torque specified in the service manual. Then divide this value by the sum of the length of your wrench plus the length of the _inline_ extension. So, *for example* , if you have a 20 inch long torque wrench and you need to apply a fastener torque of 40 foot pounds, and you have to extend it 3 inches _inline_ from the fastener attachment point for access and arc of travel, then you would set the torque setting on your wrench to 35 foot pounds instead of the service manual specified value. (20in X 40ft lbs) / (20in + 3in) = 35 ft lbs. For the average DIYer, the goal in showing the improvisation was to encourage being creative to apply a torque to the particular fastener vs leaving it without _any_ torque applied at all. Thanks for highlighting this.

The original should actually be riveted on, not bolted as I showed on the video. That's the same for the K1500 as well. If it's bolted, you're in an easier situation to replace as someone already replaced it once.
