Thanks to the responses I got to post 32294, I made some inquiries and have been told by a reputable business that the problem can be fixed.

The response I got was as follows:
"Your vehicle appears to have a common problem which can be fixed with a set of bearings to change camber and castor angles
This will cost aprox $550 and we will require the vehicle for the full day"

Anyone on here who can offer me some advise on this 'bearing' changover?

True or false? good or bad?
Will it work?

Cheers

Just spoke to the shop...

I'm no mechanic but this is what I understood him to say...

"In the front hubs, there is a swivel hub bearing top and bottom. They will fit a spacer (1 or 2 degrees after measuring problem) that will allow ajustment to castor and camber to fix the problem forever"

There you have it.

Anyone will mechanic knowledge know what they're talking about, does it sound feasable?

cheers

Hi,
They are off-centre king pin bearings. Yes they work but they must be a bit smaller than normal bearings. They come with various different amounts of offset, so the error needs to be known and bearings with the correct offest chosen.

Cheers Frank.

At a guess without reading the previous post, your GU is pulling left.
The usual fix is a castor/camber correction bearing kit being fitted to the left side upper swivel hub to relocate the swivel housing for correction. Better known as king pin inclination. Usually works and makes the GU's track straight..
Hope this helps

Most importantly - for a small change in caster like you are talking about, the eccentric swivel hub bearings used are not smaller than oem (original), but are the same. A specially machined "cup" that the tapered roller bearing runs on, is used, that will seat the bearing off set from the orriginal. This is the best way to achieve the result you are after. There are no issues with longjevity of the bearing as it may be the same part as originally fitted.
No, I dont sell them, but I have fitted quite a few, and for such a simple concept, so many people dont understand it or are confused by other methods that used to be the common fix.
Remember that anyone with the internet can answer technical questions here.
Often people who may have met someone, who once had a beer with someone, who had a similar job done years ago.

There is also a Nissan 'fix' to the GU death wobbles which involves removing one of the upper swivel hub shims to increase bearing pre-load. Sounds super dodgie to me, but I have that straight from the Giant Nissan workshop managers mouth as an authorised remedy.

If yours is pulling to the left, that will not work. Just thought I'd mention it as the wobbles may set in soon (the next item on the Nissan steering fun and games list).

My GU's front end was a PITA. It was never terrible mind you, just annoying. I want a vehicle that I can hop in and drive 1,500km's comfortably in a day. The GU wasn't it. After much frustration (and money) I sold it and bought a 105 Landcruiser. Problem solved.

Re the king pin preload your right fixes the problem and was told by Nissan insider.

re the bearings if they are offset in the way you are talking about there cant be a even load on the bearing so wear has to be a factor.

If you are talking about ' Giant Nissan ' in Perth I wouldnt believe a word that any of the workshop managers breath !

They practically ruined the second half of my trip around oz in 04.

The ever reliable 5th gear in the Patrol let go , and to our loss we went there .

They billed us for labour more than a grand for a full warranty job . We then had to return cause the rebuilt box they gave us was crap.

To Nissan Australias credit they refunded us , but 6 months after we were home, a grand goes a long way on the road .

Got my front end sorted with castor correction bushes ( wobble ) and camber corretion from Shim - align ( pulling left / chewing tyres ), cant see how it damages the bearing by offsetting it .

Glenn.

Johnsie - Have you even seen these cups?
If you had ever installed them yourself, you would see that the swivel hub is rotated and of course full contact on the bearing is maintained.
