This **** rattle - anyone help please

[lawsy]

right then, I've got a rattle/knocking form the front, does sound like it could be more front left than right but it is driving me round the bend..

So far we have replaced

Both top and bottom ball joints all round

inserted ball joint spacers so could slacken off the torsion bars

new shocks +2's

replaced CV boots and inspected CV joints

replaced both inner and outer bronze bushes..

but its still there!!

Could wishbone bushes cause something to rattle to the point that it sounds loose?
could the steering rack be loose or would I easily spot that?

The rattle..

Best way to describe it, its not constant, comes if driving along normal roads and hit a a bumpy section, small potholes, grooves etc, its the same off road either in 2WD or 4WD

off road if I go real slowly, its all fine (little knocking, but nothing worrying)- I get a chinking sound on big bumps, but that just sounds like the shocks..

so it sounds like the rattle is worse if travelling faster, ie on roads or over 15 along green lanes..

sound wise, it sounds a bit like an empty trailer does when its being towed, almost like metal knocking on metal but a loose rattle rather than a knock..

then there is the knocking - its not harsh, but I can feel it through the floor of the cab, when I get the rattle sometimes its accompanied by a knocking feeling.. sometimes the knocking with no rattle - but does seem to be getting worse

If I get underneath with wheels on the floor nothing seems loose at all

If I wedge a bar between the mounts and wishbone I can get movement, but not a lot - so would worn wishbones bushes cause any of the above?? at £190 for new bushes plus fitting I'm reluctant to just spend out if its something else.

I've heard a few people saying about loose steering racks, but again, how can a test be done?? Would this cause a rattle and knock??

anyone got any other ideas as I'm getting fed up of hearing it -I cant keep throwing parts at in the hope of curing it..

i don't have tall enough jacks or axle stands that I trust to get it up in the air and wriggle anything about, but if anyone does have some I can loan or even come to you and see if we can find it then that would be great

any suggestions


another question, how much work is involved with a SAS conversion - what sort of cost to get it done?? anyone want to do it??

Or any volunteers to give up some of your time to have a listen and help investigate would be brilliant

Do you have anti roll bars still on the truck?? If so, then the anti roll bar links are most likely the cause. Grab the end of the roll bar and see if it moves.

forgot to say

anti roll bars - rears removed,

fronts all inspected and are good - no movement at all - left side was replaced whilst doing ball joints too

Torsion bars tight?? No loose bolts at the front of the bars??

Brake pads tight in the calipers??

It'll be the bronze bushes.
2nd gens don't have steering racks.

[puddlesurfer]

Have you got a body lift?
Did you raise your front bumper?
Did you snap the little bolt off the front bumper under the wheel arch?

I did and the bumper rattled like a B****** everytime I hit a pothole.

Try banging the bumper and seeing if it rattles if it does bolt it up!

[lawsy]

Torsion bars all tight, Tony and I had them pretty much all the way out..

not sure on brakes, but rattle is much louder than that - plus wouldnt explain the knock..

top of suspension shock has a little play in it tho - might be that?? but they were new 6 months ago

It'll be the bronze bushes.

no it wont - and i thought you read posts..

bronze bushes were mentioned up there - already done and replaced - made sod all difference

d'oh, i meant steering damper - not rack..

front bumper bracket on drivers side through arch is broken - have driven with bumper removed completely to see if that is the cause - the squeak stopped, so i can rule that one out - this rattle and knock is defo underneath somewhere


I'm starting to think, give up worrying and keep driving till something breaks - I'm seeing a lot of posts with rattles

anyone any idea on wishbones tho, as original question, if the bushes are worn, would it cause rattling and knocking

The wishbones would cause the knock......first, disconnect the roll bar links and give it a try....

Anti roll bar 'D' bushes OK????

disconnect roll bar from the wishbones?? and try what???

Anti roll bar 'D' bushes OK???? - yes they seem to be in good order

the anti roll bar is all tight

[TonyN]

Leave it till something breaks, lol. I thought you said you'd found it yesterday?

I left you a voicemail to call me, was going to discuss the above as I thought it could be the wishbone bushes.. but there doesnt seem to be much movement in them - no different to the 3.0 thats just been here (but he has a knock too)

But i am thinking leave till something breaks.. just the knocking seems worse - would the body lift make a little knock seem more noticeable - as it feels worse since lifting? - you know I'm paranoid as what happened to Tims

need to see you soon about the diff drop kit, maybe have a ride in it with me and see if you can ID what it might be - its driving me nuts mate and I'm sick of pouring money into it

When I lived in the UK, I had a few Alfa's (I'm a fan). One of them had a bad knock on the suspension. I replaced top and bottom wishbones, including ball joints but the knock still carried on. Eventually I changed the roll bar links, despite them having no movement. The knock stopped. I'm not saying that they're definitely at fault but I'm always more careful with links now. I'd disconnect them (remove them altogether and try it on the road to see what it sounded like............

I've never seen wishbone bushes worn enough to rattle, but there's a first for everything, I really think it's just something loose that knocking around, doesn't seem to be the sort of rattle that has any strain on it. Will have a proper look next time you're up.
