It's Time To Swap My Differential! - BMW E90 DIY

[@CruddyPeak]

For anyone going to remove the drive shaft for any reason, careful using a 2” wrench. Proper size is 50mm and mine was so tight that i needed a 3’ pipe over the wrench just to loosen the red threadlocker. A 2” wrench (50.8mm) would’ve stripped the nut on my diff easily

With this video I was able to get my E92 335is open diff out and install my wavetrac LSD. This is a great tutorial! The 50mm nut loosening damn near required my full strength, this was a jack stand job so I think I wedged my knee under the wrench to break it loose. Also the final dropping of the pumpkin was super frustrating. Got it done though. Thanks.

[@streetdr34mer80]

Only video on youtube showing this job, thank you brother

[@friguy4444]

After thrying to find a video on the replacement or at least the removal of the rear driveshaft on a 335XI I realized your video on your LSD swap has the info I need. That rear nut that is a 2 inch nut is the one I needed to know about. Thank you again for your great videos!

[@michaelcater6754]

50mm exactly. 2in is 50.8mm can strip it. 😊

[@fjdiesi]

I agree with MD. Your car is twin to mine... for now but the other channels are so full of BS. I need to view all your published videos because I am up to my ass in parts to install to make this car untouchable. Thanks for your down to earth explanations too

[@ashleys7416]

This really helped as I wasn't sure which way to turn as it stayed very hard for so long haha 😁👍

Sweet! Looking forward to track times. Great video

[@Silent9n54]

my racingdiffs kit is getting installed today, i might even make it out to the track tonight if its all good to see if my times have improved, will post results ! Great video

[@VehicularDIY]

Nice! You'll feel a big difference right off the bat, I can dip into the throttle twice as hard before it'll break traction under normal driving. It feels like the more you push it the better it works. I made a quick right hand turn this morning in the rain and I dipped pretty hard into the throttle and my traction control light didn't even flicker. Huge difference so far. Good luck!

[@gnicevids]

Dude this is awesome. Can't wait to see the long term effects of this.

Torque specs big 50mm nut to driveshaft.... 85nm/ 62 ft lbs.... blue lock tight on splines (see note below using 2" crowfoot wrench) Rear diff bushing... 21mm back bolt.... 121 ft lbs torque spec Front diff bushings bolts... 73 ft lbs 18mm exhaust hangars, just tight. Axle bolts... 52 ft lbs... blue locktight gear oil through fill hole and torque to 44.3 lb-ft with 14 mm male hex. Note: 50mm nut torque spec using 2" crawfoot wrench: The torque wrench was 15” long from center of wrench to center of hand grip. Crow’s foot has an extra 2.25”. the torque will be 15% high or 72.1 lb-ft. The point of the formula is I set the torque wrench at 54 lb-ft to get an actual of 62 lb-ft. Thank you Moosa aka Vehicular DIY for another amazing video! Just got quoted $1200 to install my new Wavetrac LSD... instead did it myself and all I spent was $15 for the Sunex crowfoot wrench and optional but I got a $130 trans lift from Harbor Freight.

[@scottxp800]

You might think that if he can turn it by hand it's not going to do much, but the taper on the side gears and spider gears puts mechanical pressure on the clutches when power is applied. The clutches are quite small so it's not going to be as good as a real LSD.

[@S_bamblett]

Probable will take the exhaust off when I do it

[@ramp7t]

Good info here, looks like I need to swap my dif, starting to make a lot of noise. e91, 6 speed, M Sport.

[@majorkeybro]

Where did you get the LSD diff is that from an M3, a rebuild, or is just a brand new purchase? Also why did you do the yolk nut instead of the driveline bolts? Need to swap a diff and thinking of going LSD while im there, Thanks!

[@ChristianBiggins]

This is a great video, thanks! I've heard that its a bugger sometimes to get the driveshaft (from the gearbox) back in the diff? This part is missed on your assembly, looks like you got it straight in there, just wondering if you had any problems here. Thanks again.

[@smith0426]

Thank you for this, this is the best vid out there on this job. Do any of the bolts and bits need to be replaced with new ones? I think the axle bolts are aluminum

[@WalrusPowder]

I bought a spare diff to do this to after seeing your install video. Please keep us updated on how it holds up as I'll be ordering it soon

I bought a e90 m3 rear differential I thought this video would be the same but you are good enough to build your own!. I was looking for what things I would need for a install on my e90 335i could you help with that?

[@smith0426]

For the new diff, do you need to apply any lube at the pinion gear that mates with the driveshaft? If so, what kind?

Hi , I dont really know much about the differential types but I feel difference in the behavior of mine car now. I had plenty BMWs like e46 , e39 , e90,e60,e66 and now again I have my 07` 330xi M sport. I paid the XDelete software to flash my car to RWD only , but when I switch the DCS off and try drifting , the car does not slip like non of my previous BMW mentioned above. What is the difference ? WHat should I do to get it slipping day car.

Did you have to shave down the crowfoot tool in order for it to be thin enough to use?

[@tjmone74]

I'm confused about the 50mm nut. Are the diffs different by year or engine? I ask bc I'm looking to buy one that needs to be towed and I'm hoping to disconnect the propshaft so that I can use a dolly to tow. I was under the impression that these use E Torx bolts.

[@woonahk]

I am doing the same job for f25, it's really tough to unlock the 50mm shaft nut!

[@luke45412]

I'm looking forward to your follow up video. I have just installed mine and am not happy with it. It is only possible to lock in a straight line some of the time. A donut is not possible at all as it completely opens as soon as you start turning. Even if you get the wheels spinning first. Very disappointed

[@VehicularDIY]

My follow up video will be pretty soon. I'm coding out the electronic diff locker in the DSC and the brake overheat protections as well. I haven't done any extensive testing yet but I've felt the DSC interfere which could be throwing everything off. What year is your car? Perhaps the E-diff is stepping in and not allowing the LSD to function as intended. I'm hoping that overall in a straight line it locks consistently. I plan to test that by seeing if I get consistent 60ft at the track hopefully in the sub 2 second mark. With the open diff I was all over the place, 2.3 to 2.6. If you were lucky and caught a good bit of track then the right wheel would spin less but the DSC was working halfway down the track.

[@luke45412]

@@VehicularDIY mines an 03 330d so no electrics to deal with. I don't think the unit is up to the job for such a heavy car. I'm sure it will be quicker from a standstill but not for what I had in mind

Where can I find this LSD? Have a 135i that needs it. Awesome video

[@Genesislights]

How does the insert nut (the driveshaft nut) actually connect to the Diff Input Shaft? How does the spline on the Diff input shaft interface to the drive shaft. On M3, there are big flange but on this, it seems like the "insert nut" is the only thing that connects the driveshaft and the spline. Any idea what the torque spec on that insert nut? I'm replacing my pinion seal, so I would have to do this first.

[@anthonywallace3382]

instead of fighting with the wrench have somebody put it in neutral so you can rotate the shaft then back in park .

is it the same for a 335i rwd manual? where’d you get the diff from

@@VehicularDIY why it's a good idea to change an open to LSD differential in a real case?

[@VehicularDIY]

To be able to put power down evenly. Even a 330i could benefit. These cars have an E-Diff so the computer tries to use the ABS pump to help avoid one wheel getting too much power but it doesn't work that well IMO.

@@VehicularDIY No "E-diff(erential)s" on any E9x or earlier. First Electronically controlled differential clutches are all on subsequent F series and G series M models and now also the new G20 if specified (or a M340i(x) or the new Z4 S Drive M40i. An ABS controlled brake actuation is most definitely not a electronically controlled differential in any way when each is activated.

Quick question, I picked up the M factory LSD differential and housing and M factory axles. Noticed that each axle is about a 1/2 “ and give or take 1/4” shorter than the stock axle shaft. Since I shipped the factory differential housing on the core deposit I didn’t measure the width of the Stock differential housing. Can you give insight on this issue

[@dondre7291]

It could be possible that you had a 215mm pumpkin and they gave you a 188mm. What year is your car?

[@VehicularDIY]

The first thing that comes to mind is the axle might be overall shorter but are designed to stretch within the cv joints a bit when you tighten down the axle nut. I'd definitely reach out to M Factory and ask them to confirm, if you put in shorter axles it can cause a lot of problems if they happened to send you the wrong ones.
