So this has been quiet lately..mainly because I have been having diff issues
So after Millbrook training day with a noisy diff (which didn't spoil the day)
I got the car up on the ramp and stripped the diff down
After a couple of messages with z man Alex i happened to mention that I had the whitline bushings fitted!
It was at this point Alex asked me which way around I had the bushes on the ears of the diff because the whitline fitting instructions are wrong.
So if you are reading this and are planning to fit the whitline diff bushing please just look closely at the height of the stock bush and you will see the thick bush must go on top and not thin on top as whitline say.
I don't know why they have changed the paperwork but this will cause your prop and pinion to be runing out of line ...in my case over 10.000 miles this wore my crown wheel and pinion excessively untill they were buggerd.
Anyway after a very long frustrating and expensive journey my diff is fixed and quiet again
Thank you z man Alex for the information
And please whitline change those bloody instructions
