need a little help here. it happens when backing out of a spot or driving at slow speeds. mostly around turns and in parking lots. it only happens when engaging the clutch. if i disengage the clutch while its happening it stops. seems like if you try and drive it normally is when it happens. i can usually avoid it if i give it a little more gas and come off the pedal quicker. is it possible i am just experiencing clutch chatter and its transferring all the way to the rear? maybe a flywheel problem? the clutch is a few years old but seem to be fine otherwise. it holds the power when i get on it and it shifts smooth every time. i originally thought it could be differential related so i started by changing the fluid. while in there i noticed the spider gears were chipped in a few spots so i thought that might have had something to do with it. i installed new side and spider gears along with new clutches while in there hoping that would be the problem but its still doing it. any ideas? thanks
