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

Going home last night I had been doing 80-95 steady for about 15-20mins and started getting a rumbling sound from the back of the car. Slowed down and the rumble tempo decreased with speed same when I sped back up. Went round a roundabout and it disappeared only to return at about 80-85. Any thoughts?? Thanks Mike

POST 3 / ORIGINAL POSTEROriginal post

Checked all the tyres and they look OK. Felt like a wheel out of balance but it was over to wide a speed range and went away and came back :?

POST 5 / ORIGINAL POSTEROriginal post

I can live with it being a wheel bearing, posted to see if it could be more serious. Like drive shaft (not too bad) gearbox(disastrous) or other :?
