Hello fellow enthusiasts, my FG XR6T ute was involved in a low speed collision with a speed hump with a electric gate rail, which shattered the gearbox crossmember and the mini chassis rail supports needing replacement. It bounced and gouged them out after the initial damage.Also the ride height was factory as well. Could have this also affected the diff as I am sure there is a slight bearing noise/ vibration harmonic I have heard more frequently coming from the back end? I had a brake shudder issue which was a FPV fix (upgraded to 6 pot Brembo's up front) so I know how noises can come and go which can baffle the tech's from time to time.
