Knocking from front suspension

Post by Chris_D » Fri Sep 13, 2019 7:51 pm

...to be more specific it seems to occur when the wheels drop into an undulation or just after going over a bump.
ARB bushes shot? any ideas?

In other news, just finished watching the livestream of the Kinrara Trophy at Goodwood revival and couldn't help thinking that it was more exciting than current F1 races. Anyone concur? :evil:

ARB droplinks ? Top mounts ? maybe ?

Proper cars, proper circuit, proper racing. I am definitely going to this next year...I've asked the Mrs nicely :D

I definitely also have clunky front suspension! I only got the car a month ago. Ish.
Mines definitely front left related. It worst when I have just the front left wheel up on kerb and steering, when parking or something.

But yes I get a knock or two over little bumps too. But I can't make it knock when compressing it by pushing down on the car.

It's going into garage under their warranty on 25th. I'll let you know what happens!

Right.

Cars been in the garage today. And apparently they think it's absolutely fine...?! I literally told them "So a car is supposed to make a really loud knocking noise is it?" And the answer was yes.

Anyone got any thoughts or suggestions for me?

Have you checked the tightness of the bolts on the engine bay cross braces that run from the bulkhead to the suspension? I had an intermittent clunk from the front appear, most regularly when I had lock on, and this was the thankfully very easy fix.

I had this and it was the anti roll bar drop link. You need two spanner’s to fully tighten them otherwise you are simply turning the ball in the socket .....🙈

Mine was solved by doing the strut braces up.
