Hi, I have a play on my flanges on the rear diff of my car, where the flanges are connected to the diff. The funny thing is that there is no oil leak from the flanges seals on the diff casing but the play is big especially on the right side flange (5-6mm up and down movement) . Can anyone tell what it's going on? Do I have to wait for a bang???
The car is a 4wd sierra cosworth.
