hi guys

i drive 1992 patrol done 250,000 klicks of hard work country roads corragations carrying heavy loads never done the rear bearings .oil is changed very regularly
we are going on another three months of travels and i asked the local 4wd drive shop should i do the rear bearings he said it would be worth doing. a mate is a mechanic in heavy trucking said if it aint broke leave it a lone. he suggested carry a spare bearing with me which i do. but it would not be the easiest job to fix in the middle of nowhere. just asking fore the opinion of you learned lot. must add the bearings are not causing any problems and seals are not leaking.

thanks in advance
regards

Hi Al,
I think you need a press to remove the bearing. Could be difficult in the bush. I'd be checking for evidence of any oil/grease leakage, both from the bearing and the axle housing oil seal, and if they're both ok, I'd be leaving things alone. These things wear out pretty slowly, and you're unlikely to have a rapid failure.
Just my thoughts

Al
Your a worry, if you would feel better if they were changed then go and do it, but at 250,000 I doubt it would be a problem yet, and of course all the hard work country roads corragations/corrugations carrying heavy loads should be no problem to a bearing, that affects all the springs, and dampers remember at 100kph the bearing is actually turning quite slowly.My troopy now has 692000 . it is on the 2nd set , the 1st set was ok when taken out at about 460,000,

Hey Al

I do my front and back bearings weather they need it or not at 40000km, If you haven't done yours in 250000km then I would replace the bearings with new ones.

You shouldn't need to use a puller or a press to put them on or take them off, you don't have to on a Toyota any way.

If a bearing fails it's usually because of lack of maintenance, EG: not repacked every 40000 km.

I had a bearing let go years ago and learned a costly error, the bearing failed, then it seized on to the stub axle, then it sheared the axle , destroyed the diff housing and caught on fire.

The cost was $1100 for a tow truck, $1800 for a diff housing, $600 for axles and I did the work myself which saved me a few dollars any way.

The tow was only 250 kms so I would hate to be in the middle of no were and have this happen, for piece of mind just replace them.

Cheers Steve.

I suggest you go and have a look at the rear wheel bearing set-up of a Nissan. LOL

G'day

You said..... "You shouldn't need to use a puller or a press to put them on or take them off, you don't have to on a Toyota any way."

The Nissan rear wheel bearing sits outside the axle housing in a specially designed 'frame'. This frame bolts on to the axle housing. To remove a rear wheel bearing you need to press the bearing from the frame after removing the frame and axle from the housing. Rear wheel bearings on Nissans are almost indestructable.

Toyota with its floating axle is much easier to work on and bearings can be replaced with ease.

You are Correct as I just had to have a rear axle seal done on my 99 GU Patrol I did not have axcess to a press so I got Nissan to replace it in case I needed to do the bearing however the bearing was fine and the seal was only $7 the o-ring $16 the job cost me $95 all up and you do need a press to remove the bearing

My GQ had 334,000 on the clock. I had to replace a rear seal once. Thats all. Those bearings will last forever. You will not be able to change a rear wheel bearing in the bush without a press. If it ain't broke don't fix it!!!

What you can do is pull out the axle, inject new grease in without damage to the seal.

I'm off on a big trip and replaced my rear bearings on the GU at 200,000k, just to be sure to be sure.
