Wheel Bearings - 100K ?

The bearings should be checked and re-greased every 100,000km at least, depending on usage. Their condition will depend on how the vehicle has been used and if the tie rod ends are stuffed after 100,000km, it's clearly had a pretty hard life. I'd be going through everything to make sure other bits like bushes, mounts etc are OK.

Its been around Australia - and the tierod ends are stuffed (being fixed on the 19th)... It doesnt look like its done much 4wd'ing, but I think its done a stack of towing around the country, probably on dirt corrigated roads.

Check engine and transmission mount rubbers and possibly the body mounts. Get someone to start up and rev the engine while you're looking at the passenger side engine moutn, it souldn't move. The right hand side is always under compression, so should never wear out. The body mount rubbers can be checked by having someone more or less drop their weight on the bull bar and if the body doesn't move with the bar, then the mounts may have compressed past their life. My first GQ had done 100,000+km kilometres in the Souht Australian outback, carrying a fair bit of weight, and the body mounts were stuffed, as I found out later. Also check out the control arm rubbers, front and rear parts. Use a long screw driver or tyre lever at both ends and see how much moverment you get, it shouldn't be much at all when moving by hand. Check out the same at the rear end, including torsion bar rubbers.

Also check your king pin bearing by jacking up the front and then with a tyre lever or such, see if you can move the wheel in and out.

Geese these newer patrols don't seem to be made like the old tanks. :P

My GQ has 480K on the whole original drivetrain (except for breaks and tyres, and suspension coz I wanted a lift..)

I would have hoped for a few more than 100k out a set..

The later model Patrols are mechanically stronger than the GQ in many respects, much depends on how and where one drives, and how the vehicle is serviced.

Hi,

As Ray said check king pin bearings

top one gets lines on the inner from the corrigations

bottom one gets rusty from water ingress

set up the preload as book or slightly tighter

wear in these causes the death wobbles

i always do a visual on these as its hard to feel the slop in them

I had mine replaced not so long ago.. 208,000km I think I was at. Had been regreaesd before I'd say. New bearings got rid of lots of squeeks and wobbles. It also made my hubs cooler.. must have been a fraction too much friction..
