Neil AB Posted May 13, 2023 Share Posted May 13, 2023 My normally noisy diff seemed to be noisier than normal yesterday at Silverstone. I have checked the car today and there is some radial play in the the NS output shaft and the seal has started to weep. I can move the driveshaft can vertically a fraction of a mm. There is no movement in the Off side. Has anyone had a similar issue and did it just get worse or fail with secondary damage.I am booked for Cadwell next week and have no chance of getting it rebuilt before then, I am wondering if I should risk it.The Diff is a Sierra 3.92 with ZF LSD rebuilt by RRT in 2020 Link to comment Share on other sites More sharing options...
