I have a problem on my 94 Silverstone which i believe to be a broken diff.
The problem started with a little intermittent clunk when pulling away from junctions, i couldn't reproduce the problem at will so couldn't diagnose it. Travelling home the other day and the car started 'kangarooing' on bends and when pulling away with the wheels turned with a massive clunk everytime it did so, but was smooth when accelerating in a straight line or cruising round corners with no drive (clutch in).
Took it to a garage (Southern Alfa), up on a ramp. With the car in gear we can get the passenger side wheel to spin freely but merely touching the drivers wheel or drive shaft causes it to 'catch' again. Moving the wheel backwards and forwards frees it up again. There's no apparant play in the drive shafts which makes me think it's the diff that's broken. And i know bugger all about diffs other than they have limited slip to allow the wheels to move at different speeds.
The diff seems to be part of the gearbox so i'm assuming i have to replace the whole gerabox, and is different to any that were at the garage, and the gearbox seems to have different linkages to the 2 litre.
So, does anyone know anything to say this is anything other than a broken diff?
And does anyone know if the diff is integral to the gearbox or whether it is a separate unit within the same housing?
Thanks in advance even if you just read this far
