Episode 02 of 'Before & After' series is about rebuilding E92 M3 LSD.
This differential has similar LSD unit as E46 M3, so it has a problem with free play. This GKN V2 unit has a little specific opening procedure, so in this episode we show you step-by-step instructions and which tools are required to do it.
Parts used in this video:
- GKN V2 Advanced rebuild pack

- GKN V2 Opening tool

Wow. You weren't kidding. This is a full rebuild. Great video - very informational.

[@RacingDiffs]

Thank you👍🏻

[@thetoughcookie3665]

Nice video. I don't have this type of differential but these are informative always :)

[@joeyvisser6953]

Nice video. I am gonna start on the GKN V2 rebuild next week. Hopefully the LSD carrier will open with the opening tool.

[@RacingDiffs]

I'm sure it will.👍🏻

[@joeyvisser6953]

@@RacingDiffs Can you tell me where the video is where to measure the breakaway torque? I cannot find it on the channel.

Great detail in this video, I have one question from my understanding some of the diff flange have special bolt when mounting to drive shaft to counter balance the flange are you aware of this? What is your method for keeping track

[@cheapthrillsgarage]

Looks pretty straight forward. Where did the crush tube go?

[@RacingDiffs]

Between 2 pinion bearings.

[@smerhy8772]

Good work 👍🏻. May I ask if the differential preload 1,0-1,2 is the same for 215l E92 330d? Thank you

[@RacingDiffs]

Thank you, much appreciated. The preload is slightly less for 330d as it has ball bearings on a sides. So go for 0.8-1.0.

[@sebastianmorales4498]

So nice to have the special tool to open it finally. I broke my diff by trying to fabricate a custom tool to open it. By the way isnt it necessary to check for backlash as new bearings and pressure collar have been installed??

[@RacingDiffs]

Not necessarily as pressure collar pushes viscous coupler over cup spring shim so it stays in original position. Bearings are in tolerance 0.001mm so they doesn't affect backlash. Thank you for asking this question. Maybe we should have mentioned it in the video.

Shoot pining and glossy spray 🙂

[@didiss10]

Hello, thanks for the informative video, I watched it carefully. I’m planing to rebuild my LSD, it’s acting as an open diff now (used…). However, before purchasing your kit I have some questions: based on your video we’re forced to change the bearings (you cut them to remove…), so in which case people would just buy the clutch discs only ? Thank you

[@RacingDiffs]

Guys are getting clutches only when their bearing are like new. In this video, we showed the procedure of the complete overhaul. If your bearings are in excellent condition, no need to change them. You can still open the carrier unit without removing the bearing.

[@goodbling11]

Do you recommend the OEM FM+ differential oil to refill with with this clutch pack or do you guys use a different product?

[@RacingDiffs]

Only Motul Gear Competition 75w140. Without FM.

[@mot8862]

@@RacingDiffscan I use Redline 75w140?

[@RacingDiffs]

Generally you can, but if you get any chattering noises, add some friction modifier.

[@daveisasdavedoes3558]

Hi there, I have a similar issue with my 70k km E92 M3, in that it has play in the drive train, I think it may be attributed to play in the diff. I'm just curious, is would there be any additional whine or noise from the diff with the shims in place that remove the play?

[@RacingDiffs]

Not at all. It will remove play and add a bit of lockup without any side effects.

[@derekmackinnonphotography2231]

32:49 I removed my pinion seal, but need to torque the pinion nut, can this be done with all the gears still inside the case as I don't fancy opening it up, what's the best way and torque settings for this, many thanks.

[@RacingDiffs]

Go for 2 Nm than and you're okay 👍🏻

[@xiwang8469]

AWSOME! i am a E92M3 owner, and i would like to change final drive ratio from 3.15 to 3.62. i know E63M6 AND e60m5 has a 3.62 diff. So my question is does E63M6 or E60M5 diff directly fit on my E92m3? i mean plug and play. Real thx mate!

[@RacingDiffs]

Gear ratio fits, but nit the whole diff. You would have to swap gear set. E46 m3 has the same gears too. You may also find this video rather interesting. kzbin.info/www/bejne/hWmXlWOvYtuZeNk

[@xiwang8469]

@@RacingDiffs great~thx mate！

E60M5 Diff should fit directly, there’s a guy who has done it and it worked but you will need new software for the DCT

If one is doing an M3 diff swap on an e82 135i DCT, can I swap the ring gears in the diffs to keep the oem final drive ?

[@RacingDiffs]

You can as long as you keep pinion and crown ring in pair.

[@SONO4B11T]

@@RacingDiffs much appreciated

[@DFletcher413]

Is this the same build as the ready to go rebuilt GKN V2 on your site?

[@RacingDiffs]

Yes, that's right 👍🏻

[@M5F10M5]

Hi, my F10 M5 has a clunking noise in it when reversing from drive, now it has a clunk from 1-2 gear also. Is the procedure the same as this, where cam i buy rep kit? cant find any for F10 M5 on your page

@@RacingDiffs Hello,i would like to ask you about m5 e60 differential,so this diff has drive flange with 120mm ,so it can accept-fit from other bmw model drive flange with 108mm ? Thanks in advance

[@RacingDiffs]

As long as it is from 210mm/215k differential.

[@peteh81]

Is the input flange balanced ?

[@RacingDiffs]

It is balanced from the factory.

[@peteh81]

@@RacingDiffsso you keep colour markings and diferent colour torx screws on same place? Acording to manual some have balancing screws and older ones have washers. Mine is marked white so no need for them but another one i have dont have colour markings on flange

[@RacingDiffs]

Don't worry too much about that. When you change the gear ratio, colour markings don't have a point anymore. We have done that 100s of times and not a tiny vibration.

[@brendenbanks9293]

Thanks for the video buy $600 euros? that's wild expensive. Someone post up the part number for the replacement clutches and I bet you can get everything you need for less than $150 USD. The roller bearings can be replaced with an in-stock Timken part from NAPA auto for $10. The seals are also cheap. Find a cheaper way to source the clutch packs and it will be an actual real diy option.

[@hansbrix2495]

Dude, those clutch packs are custom made, and they are better than stock. The stock clutch pack isn’t available separately. The PINION bearings are not generic items either. I suppose you can use tinker CARRIER bearings, but the ones these guys sell are the right precision tolerance (that is a real thing). You really need to do more research before you make such a comment.

[@brendenbanks9293]

@@hansbrix2495 I guess you have 0 knowledge of how much these things should cost. Timken is not generic. Look them up. They are likely a better bearing that what bmw used lol. They sell clutch packs for other cars for 100eur. $600 euros for the complete kit is ridiculously overpriced.

[@hansbrix2495]

@@brendenbanks9293 I have the kit already from them. It’s a good deal. You’re a real clown if you think you can get just the larger double row ball bearing pinion for under 100 Euro. I’m holding it in my hand now. It’s made in Germany. I’ve done 3 different differential rebuilds before, I will be doing the GKN v2 next. These guys are awesome, it’s a shame you have to shitpost.

[@DaveMsport]

@@brendenbanks9293 yes, you can get crap clutch plate kits for older bmws and other cars for less than $100 but they're rubbish and they don't last long but more importantly, the clutch pack for these gkn lsds is specific. Same goes for bearings, the larger double row ball bearing is quite expensive. Only seal you can get easily is the pinion seal too as that's a generic oil seal. The output shaft seals for BMW diffs are oem only. Sure, it's quite a bit of money and might be possible to buy some of the bearings and seals separately to save a little bit of money but being able to get everything you need that's good quality, the racing diffs kits are brilliant.

[@joeyvisser6953]

@@hansbrix2495 How did the rebuild go? I am gonna start next week. The breakaway torque was new for me. So it seems I have to get a digital torque wrench.
