75 Coils on the front end?

Afternoon All!

I have owned a stretched 75 series for a number of years now and am trying to resolve a problem with a clunking front end, most noticeable when turning the steering when stationary in car parks etc!

When I say Clunk I mean CLUNK and bystanders step sideways when it happens.

On closer inspection with me under the vehicle and a token driver in the cab, I found that the clunk is caused by the leaf packs walking sideways when you turn the steering wheel - I suppose as the suspension loads up lateraly with the traction from the tyres etc. The movement is small, probably only a couple of mm but its enough.

The local garage had a go with a waddy to try and tighten the leaf straps but the effect was only temporary.

Needless to say i put a winch on the front this year and decided a new leaf pack, from our friends at Repco, for the weight with a two in lift might kill two birds with one stone - and so it did for three months but now the noise is back. Time for a lateral think and this time made up a couple of plates with a bolt top and bottom to go alongside the leaf pack to stop the leaves moving laterally. That has worked to a degree and it only emits a loud clunk just when you think the problem is solved.

My question to all is, am I alone in this and if not, any bright ideas.

Another thought tho - has anyone changed one of these to coils or is it even possible.

The problem is a purely sensory one as in all other respects this truck is a ripper.

After much mucking about and discussions with the suspension guru's I was informed that they all did this and tho they could put new springs in the front it would most likely recur. Helpful - NOT!!

Thanking you form any input
