Hey all.
Just bought a 323i and it has a little bit of a rattle coming from the diff. From what I’ve heard this is caused by bad pinion bearings, is common on the 320i, and the 323i as well, which uses the same bearings.
The 325i’s diff seems to be much more reliable in this regard. I’m wondering if it’s be possible to get a 325i diff from a wrecker and install it... Does anyone know if they’re compatible, or are the diff mounts/driveshaft different between the two cars?
Thanks
Edit: Checked RealOEM, they seem to have 25mm different driveshaft lengths, presumably because 325i diff is longer. Any idea if it'd be worth swapping the driveshaft and diff together?
