Jack both the front wheels up and get someone to turn the steering left to right and back..

Stick your head under bonnet and check for noises coming out of the steering box or the uni joint in the steering shaft under the brake booster.

am going with front wheel bearings and or kingpins..while you got the front in the air see if there is any movement in the wheels by shaking it from the top and bottom of the wheel..

Also check your shock mounts..top and bottom... a loose shock will knock like a door to door salesman...

dont forget to let us know how ya go!

I'm picking spring movement. If you don't get any noise with the front wheels off the ground, stick it back on it's wheels and try again.

try it wheels down and standing still, if its the springs you can pick the noise and having a bit of a ring to it

ok i have tried all of your tips still nothing. i changed from my drop shackles to some of fatzooks extended shackles and that has seem to of fixed it. the rubber bushes on the drop shackles where a bit flogged out so it must of been that. now i have another problem. when i go to full lock turning right the back of the inner right wheel hits the spring but going left the left wheel misses by about 50mm. i will check that the rims are the same offset tomorrow (i am sure they are). the tyres are the same size. what do you guys think the problem is?
thanks greg

my swb used to do that as well. i fixed it by removing the diffs. :wink:
there is a thread here where it was discussed but i don't think there was a solution found.
