I can't help you, altho I have a GQ and love it. I have had good advice on the Patrol forum. Try here...

Why do you think it's silly to talk about changing the castor angle/s?

Have you swapped the tyres around first..?...tyres and wheel offsets the same..?, suspension a consistent height at all 4 corners, pressures good..?, wheel base measurement same left and right sides..?

Usually there will be 1/4-1/2 degree more positive camber on the left than the right on front axle... brilliant idea in Australia..Nissan..

The offset bearing for the swivel hub will reduce some camber and change castor to help reduce your pulling to the left....as long as there are no other isues causing the effect like tyres, worn steering and suspension components, bent or cracked components etc etc.

Mate, they are simply an offset cone or cone housing for your swivel hub bearing race.

In effect though you do have a slightly smaller bearing race O/D, but this gives the ability for a thicker..albeit..offset cone or cone housing that you can rotate to adjust the camber/castor to what is better required...no huge adjustment is available though... bout 1 degree I think from memory.

I have them in my 105 Landcruiser, have had for 130,000 hard kilometres, plenty of travel, deserts, 4wd parks etc, I am on my second set of control arm bushes.

Here's an old thread here on the topic..

Has your car developed a pull to the left after a tyre rotation. I had this issue with my cruiser after a toyota service. Went to an alignment centre and they said there is nothing to adjust when it comes to castor with a solid axle front end.

Yes you can put offset bearings in your swivel head - expensive and not worth it.

My solution - I swapped my tyres back to where they where and after a week or so the pull to the left disappeared. Talking to a wheel alignment specialist your tyres can account for a lot of the pull off to one side. Also the camber of the road will account for a little bit too.

My tyres are Hercules extra tracs that have done over 60,000km now. Probably with another 10,000km to go. It is only in the last 1/4 of the tyres that I have noticed any issues with the tyres. Been great tyres so far - lots of off road - tyre pressures down to 8kpa for beach.
