My old bus had a front and rear suspension knock when purchased, just got round to having a look, the rear one was easy it was one upper rear rosejoint, changed both with new bolts...

Looks nice.....


Front shows no play in anything, all arms and ARB look fine, however you get a distinct knock when turning right at anything above crawling speed, it then won't do it again untill you turn left, then right again. It also happens when you drive the n/s wheel over a speed bump, hit both wheels with a bump and it doesn't do it....

Started with the easiest and took off the front ARB drop links... low and behold driving it like this and it was as quiet as a church mouse... couldn't get it to do it at all...

Both drop links looked fine, both moved and weren't seized, but both had slightly damaged rubbers so changed them anyway and low and behold the knock came back.... The ARB to chassis rubbers look fine and the ARB was very secure and showed no lateral movement with the drop links off so can't think it's those bushes...

I've read loads of posts on here about this but no one seems to have the definitive answer, most threads end with no answer...

Any one any thoughts please...

Thanks

A lesson learned from my car is use genuine parts for suspension components, the experience I've had is of failing parts after less than a year's service and when trying to locate a knock thinking "it can't be the new parts fitted that are knocking" and it was!!

Currently working on the rear suspension on mine, the genuine parts can be up to 3 times more expensive, but you only fit them once.

I'm only fitting genuine, came from Dan, well apart from the drop links that I got locally as needed them quick, I'm going to use it offroad so always use genuine or OEM, pattern bit's just don't last... Pete
