Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suggestion

If possible, I'd get the back end up in the air and use a plastic tube with one end stuck against my ear to try to hear where the source of the noise is.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Today during my healthcheck at centre gravity, when doing some routine bearing checks Chris discovered a noise when free spinning the rear wheel by hand. Not grinding or laboured kind, but more like a gear ticking. Just another item to add to a long list.. what could it be? That obviously made me think - time for a LSD Who's the go to guy to fix / rebuild transmission / diff and/or add LSD?

POST 3 / ORIGINAL POSTEROriginal post

I'd expect it to be a grinding noise, rather than ticking..

POST 4Original post

In my experience wheel bearings make all sorts of weird and wonderful noises, whopping, ticking, grinding, Frank Sinatra crooning.. Dont discount it being the bearing.

POST 5Original post

The answer to your last question is Mike at Sports & Classic. Does a lot of gearbox and transmission strip and rebuilds for all sorts of problems on these cars.

POST 6 / ORIGINAL POSTEROriginal post

Thanks, I'll give him a bell. Perhaps it is the bearing, I guess without someone in the know listening to it I won't know. It sounds like gears grinding very softly against each other.

POST 7Original post
