Castor correction; Offset Bearings

[MudRunnerTD]

G'day mate, i think you might be a little off track. I think your mechanic was talking about Camber Correction and not Caster Correction.

Caster correction is the tilt angle of your diff and is set using bushes in the front of your radius arms. anything less than a 2 inch lift and No caster correction should be needed.

The description that you gave and explanation from your Mechanic is describing Camber correction and can be needed because those Japs dont account for the camber on our roads. This IS neally the Biggest issue faced by Nissan owners. The Bloody Death Wobbles.

He is talking about installing a King Pin offset bearing race on the left side. I did this 4 years ago to my GUIV and reckon it is THE BEST mod i have done to the car! Well that and Drop Boxes. A decent Dyno Tune would come in a very close second though.

Check out this link for all the info you need on this great Modification. A couple of Hundred bucks will see it fitted and consider putting in a new axle seal while your there.

SafeTSteer is part of the Big Wheels Truck Alignment group. The aim of the business is to provide professional and engineered solutions to the road transport industry for wheel alignment deficiencies at a cost effective price. In today's world vehicles require more exacting steering geometry in order to alleviate early wear and reduce running costs.

We have found that many vehicles are basically set up incorrectly for our Australian road conditions.
The high road crown used extensively in Australia placed a camber bias into steering geometry that created a ‘pull left’ effect that wore tyres and aided little in the way of driver comfort through constant steering correction and added to fatigue.

With this in mind and through alignment services provided by the Big Wheels workshops, the Company identified a need for exact steering geometry specifications. Over time solutions to satisfy the need were developed by way of innovative engineering, the conduct of extensive Research and Development and the commencement of production and marketing. Now providing the solutions for competent suspension shops to correct these issues.

The courage to undertake such an onerous path may well daunt some but unrestrained by industry convention the Company commenced the long and arduous task of making something completely new from an original concept to recognised world leaders.

The company began developing a series of innovative parts, a range of machinery and equipment that allowed adjustment and correction to steering geometry allowing the vehicle to drive in a straight line. In tandem with the manufacture of these parts a laser based measuring system was developed to accurately measure the castor, camber, toe and thrust measurements of heavy vehicles. By adding the Company’s relevant sized and correctly adjusted part, or by correction means the vehicle is able to literally drive straight and the remaining tyre life is often doubled.

A portable cordless vehicle laser measuring system marketed as the Quad 4 - Laser Four Wheel Aligner was also developed allowing the accurate measurement of steering geometry on small trucks, commercial and 4WD vehicles and passenger cars.

By association with national and international industry bodies the patented parts and equipment developed by the Company found ready and sizeable markets within professional alignment workshops throughout the country and internationally to America, Africa and the Pacific.
