Clanging sound when going over a bump

[SKID]

Got an annoying clanging sound coming some where fro the front end I think when going over a bump or hitting a pot hole, seems to be on the left side as if I drive just the right hand wheels over the speen bump no noise, but of all whhels go over, get a loud clang?

I had a 2 inch lift put in it about 6 months ago and a new torque converter at the begining of the year, any suggestions would be appreicated..

Check all sway bar bushes under the vehicle they might not be tight enough and check if the rubber bush is intact it might just be the washers jingling together


Just tap it in just tappy tappy tappy

Maybe check the brake dust shield or the shockers top tube could have broken from the welds?

This can happen from an overloaded vehicle I think...

Also make sure the front springs are seated correctly. If they are not lined up with the spring mounts properly they can be noisy. Check all your radius arm and panhard rod nuts and bolts for tightness.

Check the radius arm bolts. How long has it been going on for? Is it worse when wet?

I have read the manual and can not find any reference to radius arms? where are they and or are they called by a different name?

[BigRAWesty]

There the arms which go from chassis to front axle..
The 2 bushes on the bottom of each are were caster is set. These take mode the force and flex when your axle moves, and one of mine was loose.. it had flogged the bolt out, but thankfully not the mount as that bits not changeable..

Get a mate to jump on your bull bar while you climb underneath and inspect it all...

my bet is its the rubber cushion on top the coil has shifted and now the coil is vibrating on the mount have a look on top the coil and make sure its not twisted or sliding out .

I reckon front Radius arm bushes for sure. Second guess would be a tie rod end. Third guess would be panard rod bush.

[threedogs]

Can you feel it through the steering wheel?, Maybe be something simple like a loose heat
sheild on Cat. But I'd be jacking it up and going over everything with a large screwdriver looking for play on all the suspension
components. Will be interested in what you you find. Better if you can get it up on a hoist.

[Parksy]

Do you have a bullbar fitted? Grab it on either the very left or right and try and shake it. You will know if it's loose.

Dont have a hoist but will go over everything people have suggested so far...Thanks, Will keep you posted with what I find...

Got a mate to bounch the car up and down on left and right side, no noise from right side, but can hear noise from left side, climbed in underneath while it was doing it, cant pin point were the clang/clunk is coming from but if I hold the spring, can feel a difenite clunk in the sping when he bounched it, tried holding the other components mentioned and cant feel any clink from them, could the shock absorber be shot? Took my mate for a drive to show him the spound I was talking about when going over bumps, he weighs over 120KG, and sound reduced by 7-0-60% while he was in the passenger seat, when I dropped him off home, sound was back to its normal clang over bumps etc...

[Parksy]

Buy your self a set of spring seats(or what ever they are called), the rubber bits that sit ontop of the spring. Sounds like it could be worn through.

I'll put a tenner on that...

[BigRAWesty]

Drop that side shock out and go for a drive

cant see it shifted or twisted but does look a little perished...

[SKID]

tried disconnecting shocky, noise still there, took of sway bar and turned rubbers around, solved noise, so will have to source new rubbers for sawy bar.. hope they are not too dear...

[Parksy]

Dirt cheap off eBay.

Should have , would have cleaned up lol

[NewDan]

Hey Skid, is the clunk sort of a heavy hollow metal cound, I've had that for a while, mainly when going over speed bumps but haven't been able to find the source. Dan

Thats the sound. When bouncing the car on that side, and if I held the sprint it felt like it was the coil spring, could feel a real clunk to it, wasnt until I jacked it up I could see daylight through the rubber on the sway bar, turned it around and wedged it in so was a tight fit, now no more clang or clunk...
