BMW E36 differential ratio swap ! 

I had to read soooooo many forums when I was trying to see if I could do this, I finally found a page that kinda explained it but was a struggle lol wish I had this video about 5 months ago lol good vid man. Keep them coming.

You really saved me a lot of trouble and money, I had a hard time figuring out how to get a 3.38 diff in my 328i. Thx you!

Really helpful video. In the confusing situation of having a 318ti with a medium case diff but wanting to put a small case welded back in. Right mess to figure out because the previous owner is no help so cheers for this ahaha

Awesome video dude, I will definitely swap the flanges to use the bigger axles

This swap was done on my car by the previous owner and he had hacked up the 188 flanges to make the circlip groove line up and had no axle spacers so on the first day of having the car the left output shaft just fucking snapped. I replaced both output shafts with untouched ones, used axle spacers and it's been fine without modifying the output shafts in any way, but my diff is an lsd so it might be different. I think the stubs do stick out a tiny bit compared to oem but honestly I know the splines are in all the way, the surface for the seal is also far enough in there, so there's no actual reason for it to go deeper, if anything it helps with the axle length difference, and since the 168 and 188 circlip grooves don't line up anyways pushing it in more isn't gonna secure more either. It also hasn't made any noise so I think that center bar we see in your open diff must be different in an lsd. The spacers are definitely needed tho, because otherwise you can tell it's too short and overextending the axles, plus since I didn't weld the stubs in it would pull on them and make them pop out a little bit, here since the axles are compressed they push them the stubs into the diff.

Has anyone done a small to medium case swap on a e36 318i? Or have any tips or parts list needed for the install. Any info helps.

So 3.38 ratios swap ?

Welded diff in the rain is asking for trouble😬

Could I have the link to the spaces for the ears to the drive shafts 🤞

Wait so why would you switch to a 3.18 diff , is it stronger ?, btw great video !

Would it be possible the opposite way. Small case(318is) conversation to med case diff

I am going to this swap from 2.91 to 3.45 diff, but not welded and only using STTrackpart axle spacer 6mm is it enough? Not welding it due to install of racingdiffs lsd conversion

My car came factory with a 3.91 and I want to swap to a 2.93 will me axels be too long?

What if i want use small case cap in medium case diff? Cani do it? Any advice, thank you

does this work on e46 too? nice video.

I have e46 325i, can i use e36 diff since in my country there is no manual e46? Thanks in advance 🙏

What driveshafts are those!? Thick boys! Iv got a 318 small case welded but snapping driveshafts like no tomorrow

How can i now the type of diff? like 2.93 where can i find the number of it

Sooo freshhhh 👌

I have a Kardan from 328i is it ok for 3,38 Diff ?

Swap Turkey 3.45 3.35

Wait… but what about the front diff bolt. How does that work with the small case in the subframe made for the medium case??

hi there, thank you for your great video, do you think it's be ok to replace 3.15 to 3.91?

Is it ok go without weld?
