Something has gone clunk on my corsair and now I still have gears but theres a grinding metal noise and then the rear wheel lurches forward every rotation making the whole car jump forward?!
Im guessing Diff (Jag) but all the racket seems to be coming from the box? (Which was recon'd not 300 miles ago ).
Im hoping to drop it all out this week but to be honest I haven't got a clue what the problem actually is?

Any advice on what I should look for would be GREATFULLY appreciated!!
Cheers,
Dave
