Hi all you guys,

Im wondering if any of you that own or have owned GQ safari/patrols have ever had any probs with the front end being very twitchy when hitting slight bumps on the road and then translating to a very very harsh vibration shudder through to the steering wheel and its so bad you cant actually drive out of the shudder you have to slow down untill it stops and thats usually down to around 20-30kms, Its the same kind of thing that can happen when your wheels are full of mud and the ballance is upset but all my wheels are ballanced etc, Ive heard worn Panhard bushes can cause the same kind of thing but i have Nolathane bushes in my panhard rod that are in ok condition and starting to wear but nothing too much, ive got a good working steering damper fitted to.

Any ideas guys.??

Cheers Hayden.

Swivel Hub bearings, you have done every thing else, thats all thats left, well those and the wheel bearings.
Its called wheel shimmy.

Cheers DieselBoy,

Its allso got new front Rotors and wheel bearings, Im going to try new panhard rod bushes as the Nolthanne ones in there were on the wagon when i brought it and the right one is showing slight wear so hopfully thats causing the prob.

Cheers.

Have your front rims checked to see if they are true, this shimy is common with a wheel balance or tracking issue.
I get this big time on my LWB GQ, if i have lumps of mud in the rims after being off road but i ussaly find I can drive over or under it until I get home to clean up.
Is your truck lifted, if so how much has the front axle rolled ?
Just keep looking you will find something eventually.
Good Luck

King pin angle (result of lift)?

I'd have your W/Alignment cheched if you havent already,if the caster angle is too low(no set back),steering can become twitchy at high-way speed,as Heath said

Thats if you havent sorted it all ready

Y60's also tear the panhard bracket off the chassis which can give this problem. Make sure you have enough Castor, IMO the number 1 fix for tracking issues.
I always use only genuine Nissan bushes now, they far outlast the plastic ones
