It seems like one thing after another with this car!
Been working away for a the past 3 weeks but before i went i fitted a new diff to the car as the old one was knackered.
Got back yesterday to finally take it for a test drive and above 60 i was getting a lot of rear vibration.
All i can think of is when i put the driveshafts back in i didnt put them in exacly the same (ie 1 hole out) and the are weighted or balanced?
Or the brand new second hand diff has **** itself.
The car has new tyres and has been balanced, so its not them.
Any help greatly appreciated
