ChrisValentine Posted October 7, 2015 Share Posted October 7, 2015 Hello, I haven't been on for a while!I've just come back from a 1000 mile road trip around Scotland (pictures should be up soon)Nearly back to Blackpool I noticed a thud sound from the back as I change down into second gear? When I reverse I getting a horrible grinding sound occasionally too.Again when changing down in to second I can hear a grinding and a horrible grind / rev sound?Excuse the wonderful car noise explanations...I've taken it to CotComp and he's had a look but couldn't get the car to make the noise. He looked at my discs and said that they could probably to with replacing as the corrosion will be a lot worse inside.But again today I got the horrible thud occasionally and reversing it did the scratchy grinding sound that sounded like bad engine revs....Any ideas?

WideSam Posted October 7, 2015 Share Posted October 7, 2015 Rear diff? Try changing your gearbox and diff oil and see if it helps 1 Quote Link to comment Share on other sites More sharing options...
Gaulson Posted October 8, 2015 Share Posted October 8, 2015 I would say rear diff as well, hard to tell without actually hearing it but if you have been doing a long drive it's chance something has given up the ghost. Quote Link to comment Share on other sites More sharing options...

ChrisValentine Posted October 9, 2015 Author Share Posted October 9, 2015 That was my thoughts too.I'm going to wait till next pay cheque and get CotComp to do a gearbox and diff oil change... See if there's any metal shards in the old diff oil.How much am I looking at for a new diff?Plus, looks like I'll be getting a brake upgrade if not :)Thanks guys :) Quote Link to comment Share on other sites More sharing options...
