Questiion re Castor kits (post 32294)

what bearings are they talkin about?

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.

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.
