neo2810 Posted March 5, 2012 Share Posted March 5, 2012 The car has developed a noise out the rear left which sounds like a piece of metal scraping along the ground (it's not that ). I've had the calipers and discs dismantled and cleaned up to no avail. I'm selling the car and would like this either sorted or to let any prospective buyers know exactly what they are buying so should I be looking at rear bushes, axel, something else? The sound is not constant, it seems to occur after a right turn and then disappears soon after. Quote Link to comment Share on other sites More sharing options...

ellis Posted March 5, 2012 Share Posted March 5, 2012 are you sure its not the brake dust gaurd Tends to be one of the usual suspects - I've had it. Quote Link to comment Share on other sites More sharing options...
neo2810 Posted March 5, 2012 Author Share Posted March 5, 2012 Could be but I had it in with a reputable garage who stripped the brakes and it didn't help. Quote Link to comment Share on other sites More sharing options...
neo2810 Posted March 5, 2012 Author Share Posted March 5, 2012 How do I check? It only occurs when driving and hand turning the rear wheel doesn't reproduce. Quote Link to comment Share on other sites More sharing options...
Dnk Posted March 5, 2012 Share Posted March 5, 2012 Jack that corner up and spin the wheel by hand and listen Did they take the disc off and check the handbrake ? check the wheel bearing ? Quote Link to comment Share on other sites More sharing options...
Lude Posted March 5, 2012 Share Posted March 5, 2012 wheel bearing possibly, they usually do the whurring noise first then when get bad do the scraping noise. usually a brakes noise though Quote Link to comment Share on other sites More sharing options...
neo2810 Posted March 6, 2012 Author Share Posted March 6, 2012 Bearing may be a good shout. What's a new bearing cost? Quote Link to comment Share on other sites More sharing options...
Lude Posted March 6, 2012 Share Posted March 6, 2012 Think the fronts are easier to do than the rear. Dont hold me to that though. Rear bearing is 60 on ebay with long warranty too. Depends on labour then. Be under 100 though Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted March 6, 2012 Share Posted March 6, 2012 Get the wheel off, push the dust guard away from the disc by hand, at the bottom of the discs, and try again. It only happens in corners because and the wheel loads up it will move slightly, possibly catching the guard. If it was the bearing you should be able to feel some play in it.

Dnk Posted March 6, 2012 Share Posted March 6, 2012 You'd like to think a reputable garage would have checked the dustgaurd and bearing first Quote Link to comment Share on other sites More sharing options...

Depends on labour then. Be under 100 though Dont forget the hub could be scrap as well if its the bearing thats making the metallic scraping noise You would like to think though the garage would have spotted this.

Some garages are absolutly crap. My mrs car's rear bearing was grinding awfully. They fitted a bearing in a very damaged hub and then had to be done again. By a different garage obviously. That was grinding awfully though not just a little squeek Quote Link to comment Share on other sites More sharing options...
neo2810 Posted March 6, 2012 Author Share Posted March 6, 2012 Thanks guys, I'll take a look at the dust guards on the weekend. Quote Link to comment Share on other sites More sharing options...
neo2810 Posted March 9, 2012 Author Share Posted March 9, 2012 Right, I checked the dust guards and they seem ok, however, the problem seems a little worse and it appears to be triggered on braking. It disappears when I accelerate. What should I be looking for now, discs, calipers, pads? A couple of the pads don't have anti-squeal shims so could it be worth me buying replacement shims for all pads or would it be something more involved than that?

GTR Fever Posted March 9, 2012 Share Posted March 9, 2012 crazy suggestion here...but when last did you change tyres/ wheels? probably the tyre is touching the fender? Quote Link to comment Share on other sites More sharing options...
neo2810 Posted March 9, 2012 Author Share Posted March 9, 2012 No, tyres are fine, clearance good. Quote Link to comment Share on other sites More sharing options...
Lude Posted March 9, 2012 Share Posted March 9, 2012 I think the shims just make the pads doing a clunking noise. I would get some regardless (the shims are the part that go over the 2 pins which keeep the pads in ye?) If its only happening when you brake i would say its brake related... The pads have plenty left on i asume? Quote Link to comment Share on other sites More sharing options...
neo2810 Posted March 9, 2012 Author Share Posted March 9, 2012 Aye, all pads front and back are less than half worn. All the pads have the pins and springs fitted I believe, just some are missing the anti-squeal plates that fit between pad and caliper. I can't see that being the issue though. My best guess is that it's the discs worn just enough for the pads to be catching on the lip (where there's a bit of rust). What I'm going to do is fit the new pads I have since that will raise the level and probably comfortably clear the disc lip. The new owner of the car will have to decide whether they want to replace the discs or not. Alternatively, depending on the price of the group buy, I may just fit new discs all round (or at least rear) and add the extra to the car buy price, we'll see.
