I bought pressure plates from these guys and they showed up in 3 business days from Serbia to US. Shipping was pretty cheap and parts were much cheaper than diffsonline and didn't have to send in old plates. Very good experience now I can finish diff rebuild w/ 3 clutches and 30/60 ramp. Should be perfect. Thanks.

By far the best differential video I found. Great stuff. Im excited to install my new racing diffs clutch packs in my e34 lsd. Thank you!

I'm watching this while looking at my differential in bits. Learnt quite a lot but I think i might be out of depth 😂

ok finished my 188mm 3.46. Just to add more data here... I didn't change the pinion depth spacer I used the same one that was already in the stock diff housing even though I changed the pinion which had a different spacer offset written on it (the diff housing is stock E36 M3 w/ 3.23). I got a good mesh adjusting the backlash (lsd housing preload) left (looser) by one shim set. The stock shims were 1.63L + 1.63R. I changed to 1.66L/1.60R and was done. About the crush washer.. buy two or three. Once you get it to 4 or 5in lbs you tighten by 1 degree and it can shoot to 25in lbs! Have to make very minor adjustments.

The most proper video i’ve seen on adjustment. 👌🏻👌🏻👌🏻

E to je video. A ne ona sranja napola i na kraju vise neznas nego znas. Svaka cast!

I just bought 2 sets of kits from you for clutches / clunk shim You are great. I finally found real video of someone doing work like I do . Keep up the work . Also do a video with assumption of lost side shims. 1.3mm but there could also be a preload on carrier that BMW does not publish . We can assume 2 bearings on pinion is not different from carrier ? 2 and 2 bearings and case flex . 10 inch pounds on carrier ? I wonder on new and used typical bearings . Pull a pinion out and check side flange torque drag . Do a video . Great work ! Roman .

Serbia strong. Great video!

have my 4.1 crown and pinion ready for my Z4M, so this is perfect, just need to get the kit so I have the bearing and seals required

Thank you for your videos. Very Very helpful.

Thank you for your time sir

Great video thanks for detailed video 👍

Awesome video and knowledge. Thank You

Great video. On some old rovers where you cannot buy a new pinion crush sleeve and you can’t get a shirt, they heat up the original crush sleeve with a flame until it relaxes or anneals and then you can reuse without shim.

FYI, for the sleeve used to install the pinion bearing buy and cut a piece of 1 1/2" electrical conduit - that's what he's using. It fits perfect. Don't buy 1 1/2" galvanized plumbing pipe the ID is too small.

Thanks, that answers the backlash and mesh setting procedure but still wondering about preload or clearance of the main shaft bearings ? Here you assume original shim total thickness is correct ? Should this be checked or set before installing the pinion to get total shim thickness ? Do you have a video showing how to do this ?

hello, verry nice video love your work ! i have a question for one part of the video at 35:31 min for 168 diff cases what the NM for the pinion ? it's betwin 0,6 and 0.8 NM for 188 diff cases and for 168 ? Thank You ;)

Very informative! Very nice of your company to make such videos. Question from me: can I use pinion from open diff?

The carrier bearing pre load check

I love watching your expertise in rebuilding diffs! The bearings went bad on my manual E92 330d 215L which has got a quaife atb lsd in it. I was going to have a go at renewing the bearings myself but found a 'specialist' near me who said they could do them for the same cost as i would have to pay for a bearing set. After i put it back in the car it only lasted 2 weeks then started whining again! They had the diff back and said they'd fix it. They didn't because it was whining straight away. I'm going to fit a spare diff i bought, had to get an auto 2.81 because they are common and a lot cheaper, and strip the noisy one down to see what has gone wrong. What are your suggestions as to what it might be? C clips put in the wrong way round? They have not fitted the pinion shim maybe? Thanks in advance for reading and replying if you can.

From Texas, glad I found your videos; thx for taking the time. Im curious about the choice you made regarding the diff you are working on in the video. Here in the States the OBD1 E36 automatics with the 1.8 4cylinder cars come with 4.44 diff gearing. Is it easier to obtain a 4.44 and instal the hardware to make it a posi or is it best to swap gear ratios as you are doing along with the posi hardware as a complete rebuild with new parts; once and done. Thx again for your vids.

Wich is the correct backlash adjustment size? 0.5mm-0.8mm or 0.05mm-0.08mm?

Great video. So the the shim for the crush sleeve pinon is because you reused the old crush sleeve. You sell those separately? Or do you just recommend using a new crush sleeve? What if you measured the distance between the case to the top/flat side of the pinon gear? I’ve seen some kits that help measure the pinon depth? Is that only to establish the approximate depth? I assume you always need to have the final torque resistance done by the torque reading. Also what is the approximate axial free play you have initially? Seems like 1.0-0.5mm. Thanks.

amazing video! been trying to understand this for ages. my only question is could i potentially use just the contact patch to adjust backlash? i dont have equipment accurate enough to measure backlash

Awesome video!! by far the best explained! im looking for a set of spacers for my BMW E30 lsd, something you can help with?

Were you correct in saying that proper backlash is 0.8mm? That seems like a ton. Did you mean .08mm?

When replacing the pinion assembly do you always reuse the pinion spacer that is already in the housing? The pinions have markings on them in thousands of a mm. For example one pinion says 265 (0.265mm), the other says 0.745mm. I believe this relates to the spacer offset required. Does this only apply to the original housing it was used in? So if I'm using a new pinion in my original housing I just reuse the same spacer that was already in my housing and ignore the markings on the new pinion?

Hi I bought a lsd for a miata nb and i would like how to mount and lsd properly if you do a video I would be grateful thanks 😉

In this video you mentioned torque and preload numbers for the 188 diffs. Do you have numbers for 210 units?

Great video💪 I have one question about exchange only the shaft seal. Its important to comply with the requirements pinion gear torque ? How should i do it right ? Thank u for answer .

👍👍

Care to give info for regular 168, 188 etc diff overhauls? What backlash is acceptable? Planning on rebuilding one 168L unit and don't want it to shred to pieces 100m from the garage 😂

Hi! Can you please share torque values for side caps and main cap of 188 type diff? I can not find relevant info online. Thank you very much! Great educational video!

How do you figure out total shim needed if your are replacing the carrier? Amazing video, can't believe how lucky I am that this came out just as I am working on my diff!

Thank you for this video, I will be doing this free change on my 210mm differential. For the pinion torque resistance, the BMW manuals say to measure it with no seal, but I see you did if with the seal on. I rather do it with the seal on as well is this okay?

Also, is there a way to tell wear on a used gear and pinion set? Is there a spec or way to measure?

It seems like a really low pinion preload! I believe the 168 case calls for around 3nm

I've swapped to a lsd without changing gear ratios, I've kept the shims, bearings ecc...and installed them on the same side as oem. Is it normal that if I move the unit back and forth without oil it makes a noise like a clunk? Obviously I'm talking like there is no visible play between pinion and crown, thank you

I have a 1983 bmw 528i and has a limited slip differential, but i dont know what kind of differential it is or what parts i would need to rebuild it, could you guys guide me as to what i would need? Thank you in advance!

Hello, i have found a tooth pattern of 0.13mm, according to your experience, shims of which diameter should i purchase ? (In order to make some economy)

If I’m just rebuilding and keeping same ratio, would I still need to measure backlash?

33:59 torque wrench , 0.6 to 0.8 nm ? Less than 1 nm ? Or 6nm /8nm with any torque wrench with a measurement range from 5nm to more /higher

Great video👍 what is the inner and outer diameter of the PINION BEARING PRELOAD CRUSH SPACER of the rear diff bmw TYP 188 ?

Do you have any shims/shim set for under the pinion bearing? Changed my gear ratio to 4.45 and when i put the original pinion shim and bearing inplace the pinion hits the crown gear case. Without the shim under the pinion bearing the teeths are way apart. Any tips or kits for shimming the pinion or just go and find a lathe guy and make the shim correct size 😃

I need help my bmw 640i diff pin came loose i was trying to fix it and notice i cant put the diff apart i dont have those 16 big bolts to remove the diff apart how can i do it anyone?

What step do I need to perform if not sure about the shims on half shaft is correct. Someone has messed with the diff original settings. Is there a preload check before putting in pinion shaft in? Many thanks for your time

Hi guys, I hope someone can give me some light here, I bought a ring and pinion (gear ratio 3,64) set to swap into my 188 case (originaly 2,93), I used as start point the same set of shims, but I have an IMENSE amount of play between the ring and pinion, like 3mm, which even later after swaping the spacer behind the pinion bearing was not much better, what could have gone wrong? No, I did not forget the spacer behind the pinion bearing. To verify I swaped back to the old pair and everything was back to normal. Thank you!

Hello from Slovenia! Very informative video, thank you very much for making it, I was always unsure of the procedures, especially for changing the pinion shaft and setting torque, but now I feel comfortable to give it a go. How do you find the combined two shim thickness when you are moving lets say a new lsd carrier into a different housing (e36 into e21 housing in my case) is this also done with measuring spinning torque like when adjusting the crush sleeve for the pinion preload? Where can I find the spinning torque specs for different sizes of bmw housings?

I changed the diff BMW e38 188 3.23 to e60 188 3.91. Acceleration is better. But the automatic transmission is changing leter, shifts later and therefore fuel consumption increased. What to do or how to adapt transmission with diff?

Where can I find the paint you use in the video to check the tooth pattern?

what dynamometer key use to setting torque at 31min30sec ? Thanks for all

Can you do this without the hydraulic hammer?

Hi great video. Where can I buy the tool 2?

Is the x3 diff lsd?

Can i purchase diy set of refurbished differential ?

My friend I have a e30 ix with 4.10 gear. I want to install real lsd with a 3.64. Will shims have to be adjusted if backlash is passed 0.08.

I cant remove the speed sensor. Any tips?

Does this back to work on the E46 M3 for the backlash

210 diff too 0,8? Or?

Boss, i have x1 2010 model, the front diff is gone, and im looking to buy another one, my diff details 2.79 7583773 . And it’s very hard to find, My question can i replace with other diff number? Or should be the same. Please advise thanks 🙏
