Rear end noise?

[caterhamnut]

I have a 'scraping' noise at the back of the car. Its almost like a wire brush rubbing on something, if that makes sense. It is only when the car is under power (so in gear and trickling along) - seems to be on the right of the car only.

First thought was rear brakes worn - but they seem fine. So maybe be a bearing, but they feel tightish, and more importantly they were new only a few months and not-many-miles ago. We changed both sides which seemed to go at the same time (unusual with rear bearings apparently!) - we bought the whole rear hub with bearings already pressed in.

Would seem odd that IF it is the bearing, it has gone again in such a short space of time.

The other thought is that it could be the half shaft, which is 'original' ? Could it be that?

I have to take some more things apart to check, but IF it was the bearing, could it be that there may be something wrong under the car that is putting a strain on the bearings, and causing them to fail? What could this be?

Same in all gears?

 

Having properly read the original post this is a daft question - please ignore!

may sound odd but .............

 

my handbrake cable would get slung rearwards on drive and rub on the prop. it has also been known to rb on the wheels if it come detached from the mounts.

 

If ^It aint ^yellow, wonky ^and wobbly................ 😬

I'd check the handbrake cable, it can make a horrible grinding noise if its rubbing againsts something.

Not sure if this is your problem as it would probably be audible at all speeds.....worth a check though.

Not an odd suggestion, and the first thing I thought it was, but alas not.

I'll take things apart tomorrow, but I'm certainly thinking (<6month old) bearing....

Took everything apart this afternoon (disc off, bearing hub off etc) and nothing obviously wrong. Put it back together agan, and noise seems to have gone - will keep an ear out for it, but it may have been something just rubbing that dismantling has moved slightly.....

Scraping sound on RHS only, when driver seated...I don't suppose the sound shifts to the LHS if Tessa drives? *tongue* 😬

 

Joking aside: 😬

Glad you seem to have solved it, I have had this from handbrake cablesetc it the past. You usually find witness marks on the inside of wheels, tyres and the like though. I once had an infuriating "tsk tsk tsk" from the front wheel. Traced to the tyrap I was using to stop someone nicking my wheel trims.
