Sweet EB Member 27 Member For: 19y 2m 14d Gender: Male Posted 03/07/16 05:37 AM Share Posted 03/07/16 05:37 AM Hi all, I have a BA XR6T manual. It's has a moderate power increase which has been that way for years ~250 RWKW.. I stepped off the clutch today and give it a bit and I heard a definite clunk and then a lot off woop woop noises and what sounded like loud bearing noise under coast conditions.. The bearing noise sound just like a very bad wheel bearing noise. Noise is a lot quieter when under a bit of load but gets very loud when you back off. Additional to that, when you take off from standstill, it kind of jerks the car like your pumping the brake peddle a bit while taking off. The when rolling in reverse into my driveway, it was make some pretty ugly clunking noises.. Haven't had a chance to have a look but what is everyone's thought of what it could be.. Sounds pretty bad.. Car gets driven about once a month with just over 100k on the clock. 1 Link to comment Share on other sites More sharing options...

Sounds like the pinion preload spacer has collapsed and the pinnion is dancing around. Link to comment Share on other sites More sharing options...

Quiet under load and stupid loud under deceleration. I ended up replacing the centre with a trutrack 1 Link to comment Share on other sites More sharing options...

Just whip off the diff centre cover. If you have a sedan then that's a big job haha. Check the easy stuff like centre bearing first. If centre bearing is fine just rock your tailshaft back n forth. When my centre cracked I have about 10mm of play Link to comment Share on other sites More sharing options...

What were you doing or happened when your diff let go..? I have done a lot worse and nothing has happened before.. I don't understand why something broke this time... Wasn't a full clutch dumb.. Was normally just enough to break traction. Link to comment Share on other sites More sharing options...
