leaf springs clunk/twang ?

Post by SJ »

I get a twang/clank noise when my rear suspension is tested, for instance a dip in the road at speed. Its not the exhausts or sump hitting the ground. Ive Ruled out the panhard rod hitting the diff as bent a wave. Its not the spare wheel jumping in the boot after securing it down. I am guessing it is down to the leaf springs somehow cant figure out what is going on? 🤔

If the car is jacked up are all the leaves still clamped properly. One assumes you have checked all the bolting e.g. the rear hanger.

I have two leaf parabolics on mine and had a similar problem. Tracked it down to the top of the spring at a point approx. 180mm aft of the front mounting bolt hitting the top bit of the box section of the chassis under full compression.

Glued on a rubber packer in the relevant spot - job's a good un
