Thread: Front coil fouling on chassis

If you have this issue with a standard suspension height, and assuming the panhard rod is not bent and bushes are in good condition, I would be looking very carefully for damage to the mounting points of the panhard rod at both ends. Without going and looking at it, the chassis end is on a forged bracket that is attached to the steering box and chassis. At least one poster here with a perentie has recorded a broken bracket. (I have no idea how the army managed that!)

Also, check the radius arm bushes and their chassis attachment points, although if there is a problem there I doubt the springs hitting the chassis would be the first thing you would notice!

The below photo shows where it is rubbing - drivers side, on the bump stop extension plate.

Had a good look, the spring is definitely closer to the chassis on the drivers side, however the panhard appears straight, mounts look Ok, bushes are tight. It steers well, no pulling or wander. Got me stumped...

If I put a HT spacer washer between the cast panhard mount bracket and the chassis at each of the bracket mount points, it should move the axle across to the right and even things out somewhat.

What are peoples thoughts on this?

Mine is rubbing inside of the left coil, which would suggest that my panhard rod needs to be longer. Would be nice to be able to shim it but that would be going in the wrong direction I think.

That bump stop extension plate looks to be outside the chassis. Mine is flush with or inside the chassis, and also looks a lot neater than that. Is it an after market Isuzu installation? Or have there been chassis repairs?

I can't see a problem with washers under the attachment points of the bracket though, as long as we are only talking about a few millimetres. It probably only touches on maximum spring extension. Which raises an interesting question - you don't have a broken LH shock absorber allowing excess down travel do you?
