Title: Differential question
Post by: vtulliano on October 09, 2007, 11:42:49 AM

Hi, i have a 318is, 91'
It has some problems once i press the clutch(the famous clunk noise). It seems to be the bushing etc. Here is a link to my pictures and what people have said. http://www.e30tech.com/forum/showthread.php?t=46692

So the rear end needs some work.

I know that i only have a normal differential, but is it possible or can it be a good decision to swap it with a lsd from a 318 convertible? That can avoid time replacing the old bushing from the diff. i have now. What do you guys think?

Thanks,

Vince.

if you don't mind draining the diff, you can unbolt the diff from the subframe, lower the diff with a jack with the half shafts attached, remove the diffs rear cover and have a new bushing pressed in. There are polyurethane diff bushings (bmwman91 has one) that don't require a press, also.

Now is an excellent time to check out your driveline, including the guibo, check the driveshaft for play, check the half shafts, put fresh fluid in the diff, and make sure your speedo sensor is hanging in and the wiring is still ok.

Having just swapped in an LSD into my car, I say go for it.  Cornering power feels so much smoother and it gets sideways WAY easier.  Just make sure you don't cross-thread any of the bolt holes...that kinda sucked.
