Does the backlash of GSR differentials have a tendency to get out of spec? I'm getting some knocking whenever I let go of the clutch. The knocking happens in reverse as well.

 

Bump, anyone with experience with trannies?

 

the differential gear can tend to get worn but if you have a knock noise i would put the blame on your input shaft splines being worn like these are....especially if you have a performance clutch and you like to "dump the clutch"


pics will be up momentarily.........

 

here is a photo

 

the tip is worn out?

 

the picture does not show it very well but the splines are supposed to have a shape like this /^\ and they are worn to a shape like this /\ if that helps any

with the splines like that it gives the clutch the freedom (which will most likely have the same wear) to rotate back and forth a few degrees and will have a "clunk" sound

 

my z6 used to this when i put my new tires

 

How bad is it to drive with an input shaft like this. If this is my problem that is. BTW do they sell friction plates with splines like this /\ or are they all like this /^\?

I checked it out again today and the engine shakes like mad when I release the clutch normally. The car doesn't really jerk forward or backwards too much. Most of the foce is absorbed by the engine mounts.If I release it slowly it doesn't do it.

I am now 99% sure what the source of the problem is. I jacked up my car the other day, to check the free play in the wheels when the car was in gear. The only place where I noticed that there was a lot of play was the right side inner CV joint. It also made a metalic noise. I'm guessing it most likely must be that. I didn't hear any play coming from the clutch housing or the differential. The only place the noise is coming from is the CV axle.

I'll change it when I get my engine rebuilt and I'll let you know if I was right.

 

if in fact your input shaft splines are worn you will have to buy a new friction plate/clutch and you wil need to get a new input shaft and have it installed if you are not capable of the install yourself

Yeah I know, but I noticed that all of the play that I have is due to the inner right side CV joint. So hopefully, that's all that I need to change.
