I have a 1990 Sierra 1.8 CVH which I have had from new ( yes that's 13 years ) and I have had three new clutches in it over that time. The last one was 12 months ago and now it is juddering badly again which has the been the problem with the others. There is obviously something causing this to happen. Any suggestions ? Could it be the prop shaft out of balance, flywheel buckled, cush drive on the propshaft weak? The car has done 79,000 miles.

Hi penn.

When the clutch is removed do you know exactly what they find before it is replaced.

Is the centre of the plate very loose and worn or do they find oil on the plate or anything else.

Hi Lance, thanks for your reply,

I haven't seen the clutches that came out but with the latest replacement the mechanic said that the one he removed looked like it had been getting very hot. From new the drive chain hasn't been absolutely smooth which has made me suspicious about the propshaft balance.

Persistent clutch judder without any oil leaks or obvious mechanical faults with the clutches (Ford I hope) can sometimes be caused by a worn spigot bearing, this is the one that supports the gearbox input shaft, and is located in the crankshaft.
