GQ steering problem

[jdavy5]

iv got a 1988 gq. once it gets up to about 60 kms the steering starts shakeing and it gets really bad and i have to pull over but over 70kms its ok. and iv just got a new steering damper. any ideas what it could be?

check the panhard bushes, when they are worn the will tend to cause the death wobbles on the gq's, especially if you have lifted it and fitted cheaper adjustable panhards

Strewth thats a big lift ay! you'll get 37's under the ol girl, and yep the sphinctometer peaks when the wobble hits ahhahaha

with that massive lift id also check if the caster is correct

X2 - that's actually the first thing I'd be checking with that much lift ... you obviously couldn't get casters to match, so did you fit (modified) drop boxes, drop arms or caster plates to suit a 7" lift??

Ever tried pushing a trolley at Coles with the wheels facing forward? Without correct casters, that's what you're doing ...

[jdavy5]

dont no i just got the car. and just looked at the panhard bushes and they looked f@#$ed

[High_Mod_Performance]

get the bushes replaced and that should fix most of the shake and get a wheel alignment, they will tell you if your caster is out or not

Welcome to the forum. When you get a minute how about popping over to the introductions page and telling us a bit about yourself and your Patrol.

7" is a huge lift and if it hasn't been done properly can lead to all sorts of drivabillity problems. Do you know exactly what has and hasn't been done with the lift ie, adjustable panhards and drag link, castor correction, longer control arms etc.

If the arms are angled down that much to accommodate the lift, that could be the reason for the shot bushes - do the front tyres look (from side on) like they are sitting way back in the wheel arch? And are the radius arms "reasonably" horizontal to the ground, or do they angle fairly dramatically from the rear to the front (high in the rear where they are attached to the chassis, angling down as they travel forward to the axle)? That should be a bit of a visual giveaway, but as said, you'll need someone to align it and give you the caster angles to know what you're dealing with ...

Just thinking about it now, he prob only has 5" coils and a 2" body to get the 7" so doing caster won't be too much of a problem

Good point mate ... still should have caster plates or dropboxes, so visually a dead giveaway ...

Any chance of a photo of the radius arms on the truck (for the other fella who just joined)? Front and back attach points of the arms ...

[jdavy5]
