Since I have had my car back from having the diff and pinion bearings replaced, I am experiencing an odd noise and feeling with the transmission. I have had the car back to my indie who have checked it all over and say all is ok but it might be that the bearings are 'tight' and with time it will all loosen off - they did put the effort in and even compared it to a Turbo which they had in at the time which presented a very slight similarity, but no where as severe. I have now done 1500 miles since the work and the problem remains, as follows:-
When manouevering the car slowly such as parking or putting it in the garage, if you engage the clutch in 1st or reverse, to move say a foot or two, then quickly disengage the clutch (i.e fully press the pedal to the floor), your hear and feel feint almost metallic tap-tap-tap. The first tap is loudest / most obvious and it then decreases with each subsequent 'tap'. This is very easily repeated by moving the car to-and-fro, but you do need to put the transmission under a good amount of load then quickly depress the clutch in order for it to be properly heard / felt. If I only slightly move the car a couple of inches, everything is fine.
Similarly, when changing up through the gears, as soon as the clutch is engaged the car seems to lurch or bounce forwards a couple of times before smoothly accelerating away. This is a subtle feeling, but I'm sure is new since the diff work. In summary the whole transmission just doesn't feel as smooth and true as it did previously.
The problem is more apparent when everything is warmed up, but does still occur when cold. I'm pretty certain that the problem was not there before the car had the diff work done.
I have had a search through previous posts and the only similar issue was related to a failing clutch, or related clutch part.
My car has done 56k with comprehensive history and has been very well looked after. It has never has the clutch replaced or had any previous transmission work.
Has anyone experienced this or any thoughts to the cause and solution? (am I just the victim of bad timing and is my clutch on it's way?!)
Thanks,
Chris.
