wierd driving problems---NEED YOUR INPUT!

[rwdfan]

Hello,
I have a 92 325I. around 110,000 miles on it. I recently replaced the tranny (used, not rebuilt) and I put in a new clutch about 5 months ago. Recently, I've been hearing and feeling some wierd things.
For example, if I'm driving in 1st gear, and I hold the speed at a high rpm (like 4500), and then I hit the clutch all the way, the car jerks and I hear something like a bang, coming from the rear tires that sounds like there is some kind of lubrication missing. Also if I'm driving normally and changing gears, the same thing happens sometime. It sounds like the clutch is too rough in cutting off the power.

Also, the second problem is that if I floor it, I get a wierd feeling coming, again, from the rear tires. Its as if it feels like its too rough again. Not sure how to describe the problem any further as its a pretty hard-to-describe problem!

Anyways, I would really appreciate your inputs as to why this could be happening.

To be honest with you... I'd take it to a mechanic... as there is not much you can do besides get it on a lift your self... jack it up and make sure everything is right...

Tranny bushings... lub in the tranny... the rear end... if it is all sound and good to go... then I'd start looking at having someone with more knowledge take a look and have them drive it... and work from there.

Sometimes problems like this are hard to diagnose on the internet only because we can not sit in the car and hear the problem.. as you cant tell us where it is coming from exactly... and what is going on...

How fast are you slamming your foot on the clutch while doing the 4500 rpms in first gear?...

If you slam on it... your putting a crap load of strain on the clutch it self.

Have you checked the gear oil level in the rear axle? Check your bushings? (especially the subframe bushings...). How old are the rear shocks? Jack up the rearend and rotate the rear tires fore and aft to see if you can hear it.
