Clutch Problem Possibly?

[Saukk]

Hi all,

I recently bought a 2000 BMW 328I. It has 104K on it and has a 5 speed manual.

Now, I am having a problem when I shift . The problem is when I put in the clutch to shift, I hear a thud (pretty loud one), and when I let out the clutch after I shift, I hear another thud (about the same volume -- sound wise). I don't really notice any weirdness in regards to the actual shifting of gears. It does this all the way from 1 - 5, not just on select gears. This is making me believe it is a clutch isolated problem...

Any ideas of advice? I'm contemplating taking it back to the dealership if it turns out to be something very costly to fix.

Thanks for your help.

Update:

It seems the noise, upon further inspection, is coming from the REAR of the vehicle when I put the clutch in and out. This is a bit more troubling to me. Could it possibly be the driveshaft, differential?

Thanks,

Check the rear mount for the rear differential. Seen quite a few of those go bad. Check the rubber in it for cracking or tearing.

Are there diagrams available online that can show me what the rear differential looks like?

Thank you for your time.

If you look in this diagram HERE at the rear of the diff where the bolt is shown is where that mount is.

I actually took it to a person I know that works on BMWs exclusively.

Took him about 30 seconds to find out what was wrong, turns out it was my rear differential cover bushing.

He also said I need to fix the following:

o) Rear Diff Cover Bushing
o) Front Right Control Arm (loose, cracked)
o) Both Control Arm Bushings (loose/woren)
o) Intake camshaft sensor (computer said it was faulty; has failed 67 times)
