I am not sure is this really a problem or I am bad driver :-)
Anyway, since I bought the car problem apears as follows:
when I drive in reverse, car doesn't move smooth, it stalls.
I am giving my best to describe this, not perfect english speaker :D
I select reverse, releasing the clutch slowly with about 1000rpm and it move ok, but when I try to press cluth I can hear the ''clunk'' sound from behind.
Also when moving in reverse with pressed clutch to the floor, and then trying to release it a little to continue moving it ''kicks'' one or two times and clunk noise is hearable again. I really think that I have bad driving technique, but I drove lot's of E36/E34/E46 cars and never noticed any problem like that.
Any help would be great
:cool:

It might be your rear differential bush - This makes a loverly clunking noise when you engage reverse if it is dead.

Pretty simple to replace - if you drain the diff of oil and just remove the cover.

center bearing NEW, engine and gerarbox mounts NEW, handbrake off LOL :cool:

Let's try like this: when clutch pedal lifted off with small engine power (800rpm cca) and driving in reverse, then fast pressed clutch to the floor makes a noise like ''clunk'' hearable somewhere between diff and drive shaft. But everything is fine in normal driving :roll:

Check the bushes on the rear axle, the two at the sides and the one on the back of the diff. Possibly starting to wear or the rear brakes are dragging.
Let the car roll to a stop in reverse on level ground and just as it stops if the suspension rises slightly they'll need checking.

Is the clunk all the time, or just when the engine is hot? Is it more or a judder than a clunk? If it is then it might be worth changing your clutch fluid.

god damn man :cool: , I've changed clutch fluid a month ago.
Things I haven't replaced are diff oil and this rubber between gearbox and shaft. Well it's cheap so I could replace them next week and see for changes :wink:

What should I replace?
