pbryant_knight Posted November 22, 2012 Share Posted November 22, 2012 (edited) Hi all. I have a noise coming from my front wheel. It's intermittent but seems to be happening more often now. It starts when I'm moving generally over 50 and increases/decreases with speed but remains until I stop. It sounds/feels like little thuds, almost like driving on sleepers but not as intense? Any ideas? I was thinking maybe wheel bearing. Peter Edited November 22, 2012 by pbryant_knight (see edit history) Quote Link to comment Share on other sites More sharing options...
Iky Posted November 22, 2012 Share Posted November 22, 2012 Jack it up and spin the wheel, Check for play or noises to see if it's brakes warped or bearing gone. Quote Link to comment Share on other sites More sharing options...
pbryant_knight Posted November 22, 2012 Author Share Posted November 22, 2012 It has new discs and pads all round. Quote Link to comment Share on other sites More sharing options...
Dnk Posted November 22, 2012 Share Posted November 22, 2012 If it speeds up and slows down it can't be many things Wheel bearing something stuck in the tyre other fault with tyre, caliper begining to seize back plate catching the disc Do you get any wheel imbalance, shaking of the steering ? Check to see if one side feels hotter to the other after you have been driving or just jack the front up and spin both sides to see how they feel to each other Quote Link to comment Share on other sites More sharing options...
pbryant_knight Posted November 22, 2012 Author Share Posted November 22, 2012 Cheers. There is no steering vibration and its not just when I brake, it's where I'm just moving along I know the calipers did/do jam slightly, I had them freed when I got the brakes done. If it was the bearing, is there any way to check specifically. Quote Link to comment Share on other sites More sharing options...
Dnk Posted November 22, 2012 Share Posted November 22, 2012 The brakes sticking should really be fixed as this can cause judder and wont help if your trying to check to see what the bearings like. To check the bearing you'll need to make sure the pads are free from the disc first then rotate the wheel and feel for lumpiness and listen for any noise, then hold the wheel at 9 and 3 and try to shake it back and forth gently, then the same at 12 and 6 Quote Link to comment Share on other sites More sharing options...
straightsix Posted November 22, 2012 Share Posted November 22, 2012 If it's a wheel bearing I have a pair of front hubs (non ABS) for sale with good bearings Quote Link to comment Share on other sites More sharing options...
pbryant_knight Posted November 22, 2012 Author Share Posted November 22, 2012 I think the caliper is sticking slightly still but this feels different. It's a one of those things where you can't really explain in words you just "feel" it. I've had calipers that have been seized before and this feels like a different motion. Its not a judder per say it's like a noise, with a bit of vibration, Intermittent, "dum, dum, dum, dum" seems to increase/decrease with speed........................Told you it was hard to explain in words. It's due for MOT next month anyway so i'll need to get it sorted by then. May take it and let the garage tell me what it is lol. If it is a bearing, how much you looking for for the front hubs?

pbryant_knight Posted November 23, 2012 Author Share Posted November 23, 2012 After taking everything everyone has said into account I'm starting to think it may be the calipers. Checked the n/s front wheel and it was really hot. Might be worth replacing these first. Anyone got any jspec n/a calipers in good working order going cheap?

Peter Classic seized caliper symptoms. how handy with the spanners are you? You could possibly just refurb it yourself with new seal/dust boots. Also cleaning the pistons with some fine wet & dry.

Dnk Posted November 23, 2012 Share Posted November 23, 2012 (edited) Be wary of buying old cheap calipers as they will soon seize up just like the ones you have now unless they have been refurbed. If you have j spec 2 piston calipers then it could very well be that the caliper is sticking on the sliding pins as well as it being the pistons seizing. If your pistons are pitted then their scrap, if its only light surface corrosion then you might get away with fine wet and dry. You can buy pistons and seal kits from Chris Wilson While your looking at the fronts it would pay you to check the rears as they will be close to doing the same as well Edited November 23, 2012 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
pbryant_knight Posted November 23, 2012 Author Share Posted November 23, 2012 I had the calipers all cleaned up when i had the new front discs and pads put on. Bear in mind my spanner may as well be made of chocolate for how much use i am with stuff like that. Any work that is needed will be undertaken by a garage. Cheers for the advice Dunk. So does anyone have any cheap calipers that have been recently refurbed properly for sale lol. perhaps after a big brake upgrade? Quote Link to comment Share on other sites More sharing options...
Abz Posted November 23, 2012 Share Posted November 23, 2012 Just thinking outside the box here but possible wheels nut fully tight? I remember when I had one which wasn't too tight after tyre fitting, though to be honest I should have checked it afterwards myself. Quote Link to comment Share on other sites More sharing options...
pbryant_knight Posted November 23, 2012 Author Share Posted November 23, 2012 Hmmm, i'll check that now just to be sure. Quote Link to comment Share on other sites More sharing options...

Ian C Posted November 27, 2012 Share Posted November 27, 2012 Check your tyre - I had one near it's end of life suddenly deform on the sidewall, I got a "bomp bomp bomp" noise from it, but no handling issues. Spin the wheel and watch the sidewall edge on to check Quote Link to comment Share on other sites More sharing options...
