slabside Posted June 8, 2009 Share Posted June 8, 2009 Got a metallic clattering from the offside front when driving. Just fitted new discs and pads, new one shot in the swivel, greased and adjusted the bearings. Now, after a few miles i can hear a noise with the window open. It's pretty loud over bumps aswell. All suspension mounts seem ok, the noise is while driving. Noise could have been there before I did the work, just never noticed I don't know if the C.V joint makes a noise when on the way out ? or swivel bearings ? Anyone with a clue what I need to get before I pull it apart again? Thanks for any advice offered. Quote Link to comment Share on other sites More sharing options...
BogMonster Posted June 8, 2009 Share Posted June 8, 2009 Brake disc guards? Quote Link to comment Share on other sites More sharing options...
slabside Posted June 8, 2009 Author Share Posted June 8, 2009 Thanks for the reply. They were pretty rotten but their not touching. It is a much heavier noise, like with the rotation of the wheel, but noticeable on bumps aswell ? Quote Link to comment Share on other sites More sharing options...
BogMonster Posted June 8, 2009 Share Posted June 8, 2009 Check the steering damper stone guard - Discovery ones break around the weld and make a hell of a clatter over bumps. Took ages to figure out where it came from. Check shockers/shock bushes are OK. CVs normally make a cracking noise when you are cornering, either that or a loud bang and then something locks up solid which is nasty. Jack up each wheel and spin it on the jack and see if it feels and sounds OK. What age of Discovery are we talking about here, what mileage, what engine/gbox?

slabside Posted June 9, 2009 Author Share Posted June 9, 2009 Sorry, it's a 300Tdi '97 vintage with 132,000 on the clock. Everything is pretty standard engine/box/suspension wise. It sounds like it's coming from the hub area, but then noises from below can come from anywhere i suppose. Will have another look tomorrow and check out the steering damper. Cheers.

slabside Posted June 10, 2009 Author Share Posted June 10, 2009 Well I have been underneath it again tonight, can't find anything loose suspension wise, exhaust etc. Wheel bearings are all adjusted, levels are all ok (gearbox,axles etc). Baffling me and bugging me in the same amounts. But when you drive there is a rattling, clattering noise that is worse over bumps. Propshaft u/j's are all ok, beginning to worry that all the obvious has been checked so it could be something internal and expensive in the tranny ? I know it's hard to guess at a noise, just thought someone might have had something similar, might end up giving it to my local landy specialist, see if he can find anything ??

Rolly Posted June 11, 2009 Share Posted June 11, 2009 Did you replace the anti-rattle clips when you put in the new pads? Mine were rusted to buggerey when I did mine and until I replaced them it rattled over every bump I hit. Quote Link to comment Share on other sites More sharing options...
slabside Posted June 11, 2009 Author Share Posted June 11, 2009 Yeah, changed those for some nice new shiny ones Just read another post where someone said their transfer box sounded like a bag of spanners !! It does have that kind of noise to it but this is noticable over a bump aswell as coming and going while driving. Quote Link to comment Share on other sites More sharing options...
cipx2 Posted June 11, 2009 Share Posted June 11, 2009 Find a place with bumps/whatever where you can hear the clattering then go back and drive again through them at the same speed but use your left foot to keep a light pressure on the brakes. That is gentle brake with your left foot, press the accelerator a bit more to maintain speed and drive through a road section where you know it clatters . See if it clatters any more.

slabside Posted June 12, 2009 Author Share Posted June 12, 2009 Nice one cipx2 ! Now you have to tell me what's causing it. Noise definitely stops when you brake, so what have I left loose/forgot to do. Is it brake related or more sinister, cause it don't sound like any brake noise I heard before Quote Link to comment Share on other sites More sharing options...
cipx2 Posted June 12, 2009 Share Posted June 12, 2009 It's one or more brake pads 'dancing' in the carrier. They are a bit shorter than the space in the carrier. The anti clatter springs limit the side to side movement only, the up and down movement is not restricted. No need to worry and nothing to do about it. It will go away after a while (1-2000 miles or even more, depending where/how you drive it) when the dust/mud/brake residues will start to accumulate. Occasionally you may also hear a "click" when you apply the breaks, no need to worry either, same cause. Quote Link to comment Share on other sites More sharing options...
slabside Posted June 12, 2009 Author Share Posted June 12, 2009 You are a star my man. It started to not even sound like it was coming from a wheel. I was thinking all sorts of things. Perhaps I should go for a spin in some mud and snot at the wekend to gum them up a bit Thanks for the advice. Quote Link to comment Share on other sites More sharing options...
Aragorn Posted June 14, 2009 Share Posted June 14, 2009 I'd be checking the calipers are actually tight before assuming all is ok just to be sure Also, you can try removing the pads and putting a thin coat of copper grease on the rear of them if you havent already. The grease will help the pad stick to the piston and might stop them moving as much. Just keep the grease away from the disk and pads surface.

slabside Posted June 14, 2009 Author Share Posted June 14, 2009 Yeah mate, no worries, checked the calipers along with everything else I could think of Been putting copper grease on all brakes since about 1981 when the sliding calipers on me 350LC kept seizing !! In fact I have been cleaning the edges of new pads since then aswell to prevent sticking, but it seems in this case I might have contributed to the noise......... Doh!
