Can you Put a Differential from a BMW E90 328I into a 323I???

[@Dirtydangles660]

Thanks for the video man, i have a 08 323i and its alot easier to find a 328i diff and driveshaft/axles than a 323i diff

[@Dirtydangles660]

Just putting this out there for anyone else going to do this job, I bought a 328i rear diff and just swapped the axle stubs and it infact worked and I didnt have to touch my stock axles

[@bobsuruncle8520]

Is changing the stubs on the diff hard? Are they just bolted on? I haven’t removed mine to look yet

[@Austin-jm7lp]

@@bobsuruncle8520any updates on this? trying to do this to my 323 as well

[@Austin-jm7lp]

this does not work the stub spindles are shorter on the 323

[@gabrieles02]

What type and size of screws are holding the axles? I need to order some tools to get my diff changed

[@combustiontherapy2222]

The CV axle bolts are E14 (x6) per axle

[@DenishMohabit]

Would i need to change the driveshaft if my car is manual? And the donor car is manual too :

[@analoggeneration385]

That I am not sure of. Sorry

[@domkraggp9944]

Have exact same issue , the diff in my 323 is whining , i know its a pinion bearing ; but why does it fail prematurely and does this issue affect all 323 including facelift ?

[@mustangmounties4806]

Was the donor car automatic or manual, and is your 323i automatic or manual? I will be doing the same swap soon. The diff in my 323 is finished

[@analoggeneration385]

Both the donor and my car were automatic. I am not sure if it makes a difference

[@combustiontherapy2222]

@@analoggeneration385 The only difference would be the final drive. The manual having a 3.23 ratio while the auto has a 3.73 ratio. This makes for faster acceleration with the differential from an automatic donor swapped into a manual E90.

@@combustiontherapy2222 so I have a 3.73 ratio diff I got a 2007 328i? Was trying to get mine welded heard I might not have to do that

[@combustiontherapy2222]

@@tonyrincon6400 This would be an open differential, while welding might be an option it definitely wouldn’t be the most advisable one especially for a street going vehicle. There are many LSD options available that can be fitted to these differentials.
