Torque to 200-300 ft lbs !!! Sometimes they have zero torque when you take the cover off. 200-300ft lbs is a good number for used bearings.

Meritor has a spread sheet on Google. I printed and taped it to my toolbox. Steers, non-drives, drives, Pro-Torque, jam nut, under and over 2 5/8"... all have different torque values and procedures. Dont just guess like this. Best case, you either smoke and bearing and banjo. Worst case, ya lose the whole assembly and end up in the clink.

And this is why I don't sit next to trucks on the road very long

Well i just discussed this with a mechanic today he said to set the preload tighten it as much as possible while spinning it then back off a full turn will be lose then put your nut on and bar on the nut and dont press down just let the weight of your hand on the bar do the tighting when it stops going down with juat the weight of your hand on it your good you have set the pre load put the rest the shit back on in order it was taken off tighten outter nut tight as u want and put lock tabs down ....dont forget to add some gear oil in the bearings and dump the rest in the rear diff he said never tighten that inner nut by torqing it tight or u will blow everything out and end up replacing it all the outter nut he said is the one u want to get pretty tight

According to stemco torque procedure it's 200ft lbs back off 1 full turn torque to 50ft lbs and the back off 1/4 turn check endplay is 0.001" -0.005" If its a proloc it's 0.001"- 0.003" If you have the spacer cone in-between the bearings you torque to 300ft-lbs You should be using a dial indicator to check your endplay. Bearings actually like a bit of preload but the only way to check for that is to wrap a rope around your studs and pull with a fish scale and see if the pulling force is with in manufacture specs

The torque spec is on the axle nut

Thanks to hacks like this guy I'll be keeping an eye out on the highway for burnt up wheel ends heading towards me and my family at 80 mph.

Listen kid's DRUGS ARE BAD!!!!!

That style has a spacer cone. Tight as possible is the correct answer

Just so we clear the air on this, I work for Freightliner. You install the hub and rotate the hub counter clockwise while tightening the nut, and torque nut to 500 ft.lbs. That’s it. Don’t listen to this guy.

Wheel bearing torque doesnt matter, they have some sort of retaining nut or tabs or locking device. Endplay or backlash between .001" and .005" is what matters

Tighten all the way, then back off 1/4 turn. Done it like that for years.

That is a conmet preset hub. It's 300ft lbs. It has a spacer in between the bearings. That sets the end play. If you don't tighten it tight enough the bearing will spin and destroys the cone witch will put metal in the oil!

Put the torque wrench at the value the manufacturer has set them at. Also, follow all the other tightening sequence steps.

What's the point of an official torque spec if you're just going to eyeball a figure?

What ! Oh boy clown school training 🤣

I recommend full power with the impact gun until the wheel doesn't turn anymore and reassemble pretty much as useful as this video

So just neglect TMC RP 618? Even though this is a unitized hub assembly it still needs to be properly torqued and set, even if you are reusing the assembly on the same wheel. The penalty for neglecting this RP code is a 5 year federal prison sentence if it's just a wheel off, if someone dies it's considered murder on the person who service that wheel hub bearing.

Seen it 100 times. Never asked dad what that socket was for. I never worked on a truck in my life.

Ima let the mechanic make his money on this one chief

Wow I didnt know the drive axle look like a regular pickup truck drive axle. I thought they would be beefier than what I just watched 😱

200 ft pnds IDONT think so

No… there is not a specific torque spec in that regard… stop “teaching” wrong information.

You wouldn’t need to retorque your wheel ends if they were done right.

YOU ARE NOT DONE!!! You need to fill both of the wheel hubs back full of gear lube & refill the differential!!!!

Wow. If your going to torque wheel bearings without a spacer cone, never go higher than 50 lbft. You can torque a conventional hub bearing setup to 50 lbft while rotating the wheel and it will be just fine. 200 lbft!? Not so much! And don’t be the guy that globs silicone all over the axle flange. It WILL leak. Get a gasket and put a thin layer of rtv on it so it stays in place during assembly. If the surfaces are clean, the gasket will last for years.

If you don't have .001-.005 end play on wheel ends, you are not torqued correctly and not only is that unsafe and can cause a potential dangerous failure, but you're also voiding any warrenty or liability the manufacturer had or has.

Bahaha hahaha 🤣

Tightened it up and back off a quarter turn and you be good! Follow that advice, you’ll be broke down with expensive repairs!

It baffles me why people still use WD-40 instead of a proper creeping lubricant

Step one verify you have LMS or pre-set hubs if you don’t , dont use this procedure!

I just reckoned slamming straight in on the axel. Only 500 truck axels ago so might not know much.

Bruh🤣😭 .003-.005 endplay of the wheel hub. Not .0000000001 endplay you've got tp leave room for heat expansion and enough so the inside seal works

That folks is what a backyard hillbilly does. Take you truck to a mechanic that will follow procedures.

This is a modern style preset bearing with the other 2 common styles unitized and conventional. Setting and checking the tq on either the conventional and preset is extremely important. And often overlooked, causing 350 lbs at 70mph to slam into a mini van of 4. Do not do anything you have been taught and certified to do. Read your service manuals for proper intervals. Know a teacher from school whose employee messed up one thing killed a mother, father, and her daughter. The son had severe injuries. In a wheel off indecent. Charged with murder got 8 years 6 on good behavior. And a massive fine. A fucking joke this can be "explained in 60secs" and its a insulting to my/our industry. "I recommend 200ft/lbs" Congrats, you just became liable for that wheel. I hope it's right. You seem smart don't spew bullshit online. Like some of the comments posting info for the conventional setting of a wheel bearing. Do that to a preset you kill someone. Straight up scary, man.

What is he accomplishing by torquing the hub just out of the blue like this. If that hub doesn’t have the preload spacer in between the wheel bearings 200ft lbs is going to burn them bearings up

Do not listen. Every wheel end could be different. You could also have a crush sleeve in between the bearings that require a different torque.

Is there a difference between the driver's side bearing threads and the passenger side threads? Wouldn't one side tend to tighten the bearing space and the other loosen?

Theres a special torque sequence unless its a preset hub dnt do this u will fuck up some shit and cost u lots of money

What are the torque specs for the axle flange bolts of the rear axle drive? I've just replaced the oil gasket for leaking oil on the rear flange of my Freightliner Cascadia. Thanks!

Didnt mention about the spacer......without that, the more you fuck around, the more you gonna find out.

The torque is 300 pounds for drives, 200 for steers. Make sure you get proper training people. This wheel end is gonna need redone soon

NEVER BUY TOOLS FROM HARBOR FREIGHT!

the buses I work on have a two stage torque procedure 250nm spin the wheel 20 times then 1000nm

I don’t have a Milwaukee so I wasn’t able to finish the job.

What in the super trucker is going on in this video and comment...stay in your lane lmao

WTH. This is some of the worst information I have ever heard. This is a great explanation on how to smoke a set of bearings. Stemco has a great little chart for how to do it properly. Most times if you follow the torque specs the end play will be spot on.

Why are you so proud of that red Milwaukee drill that mallet your holding is American-made estwing mallet. Yhat you should be more proud of.

Do more videos

Woah woah woah! No dude

200ft-lb preload on the bearing will burn it up.

50 lbs and advance to the next closest lock position.

Don’t want to go over, don’t want to go under 😂 duh

pardon me... but he reference torquing it to 200ft lbs? and then request that if the lock doesn't seat, that you should under torque or over torque the nut for the lock to seat?

Aren’t those harbor, freight, jacks, known for failing?

That style nut actually does torque less then 200 on final torque to achieve proper hub and bearing setting but 🤗 fuck it

I hope this is just a joke. Please don't listen to this video.

Two hrs because of the cussing and tool search 🤣🤣🤣

Looks like potential injuries

No.. please find another profession

This is typical of KZfaq. Bad info being put out there and people not knowing any better putting it to use. 12 year diesel mechanic here. Will what you did work, prolly. If it fails you got evidence for the district attorney to use to put you in prison. I see you commented about using factory specs on used bearings, well where is your dial indicator to confirm there within .001 to .005 acceptable play? There could be slop or to tight after what you just did, but fuck it right? Hopefully it's a quick death for who ever that tire slams into on the road.

Use breaker bar not torque bar to loosen !!!

Please in the name all that is holy do NOT do this, please!!

You might want to put some oil in those diffs

woah.....literally everything is wrong

Dude your so wrong with that pro torq nut. Why do most truck drivers think they are mechanics. Even a truck stop so so mechanic knows better

Torque them at least 12,000 ft lbs. Nice hub pilot rims too!

I think they killed a couple people

Incorrect

Wrong. Absolutely wrong. Wrong wrong wrong wrong wrong!!!!! WRONG!!!!!

abSOLUTEly not!

You have no business doing this and you certainly don’t have any business teaching others how to do it.

Wow what bad information

Those arnt lugs those are axle hub bolts this guy isn’t a mechanic or even close

It's not right

Do not do this

I knew it was bullshit when I heard the words" harbor freight".

What your mallet isn't made by Milwaukee too?

If you have a spacer - torque to 200ft.lb. If you don’t have one - torque to 200ft.lb., then loosen 1/2-3/4 of a turn, torque to 50ft.lb., then spin the wheels a fe turns each direction, then repeat the procedure 2 more times.
