Wheel Bearing Checks

Hi All,
I am sure by now that you all realise that it is quite important to regularly check the wheel bearings on your LCs, particularly if you are doing a lot of off roading.
The standard way of checking is to jack the wheel up, hold it at the top and bottom (12 o'clock and 6 o'clock) and then try to rock it back and forth - if you hear a clicking/clunking noise it means that your wheel bearings are loose and will most likely need just tightening up. If you are getting vibration as well then they may well need replacing.
Ideally you should be looking to get your wheel bearings and CVs stripped down, cleaned and then repacked with new grease every 20-30,000 miles, half that if you are off roading a lot.
OK, that is all pretty standard stuff, however I have come across a few instances recently with the back wheels where the standard check didn't reveal any problems, however pushing and pulling on the wheel on the axle has revealed some movement - one car recently must have had almost half an inch of movement.
So the next time you check your wheel bearings, try the pushing and pulling trick on the rears to see if you have any movement there.
Also note that if you hear quite a major clunk when do the standard check on the front axle it could be your steering pinion bearings on their way out which will normally cause steering wobble, loose steering.

Hi Julian,
Just been through that with the rear bearings, you are right there was
hardly any play with rear wheels (12-6 and 9-3)(KZJ70 Land Cruiser II).
But when pushed in and out revealed a 1/4 of an inch play.
Took out the rear drive shaft to inspect the play and yes it moved around
the drum brake something chronic, so had the bearings replaced which is not
a job that is easy to do like the front ones...
Luckily my mate done them for me who had to make a special tool to press
them off the shaft.
Just recently repacked one front side as well which is actually quite easy,
at that point I noticed the seal had gone (the one that stops stuff
progressing from the brakes to the wheel bearing) so have just ordered
(received now) the seal kit from Toyota which was not cheap for a few seals.
Will repack and do the seals on both sides shortly and all should be good
for a while I hope.
Thanks for the information.
Martin.

I've had to have both rear axle seals replaced in the last 3 years, and
they were doing rather too good a job at lubricating the rear brakes ;-}

Hi Chris,
LOL nothing like lubrication.
I done the rear axle seals when the bearings were replaced(about a month
ago), they cost around 30 quid for the pair.
The front(CV/HUB)seal kit was around a whopping 200 quid for the rubber
seals, front hub gaskets and other seals I need to fathom out when I strip
it down.
Don't you just love Toyota pricing ;-), maybe I should have brought the
one's from Milner, but I like things to last and not sure about the kits or
even if Milner do them.
Cheers
Martin.

Doh, the other day I was scratching my head trying to work out why there was so much movement in the bearings on the shaft, but no wobble - I forgot the halfshaft side of the equation :)

Hi,
You really need to remove the half shafts on the rear to get a proper
feel. The shafts are a tight fit in the diff splines and quite rigid so
they stop the wobble you'd check for on the front.

Hi Julian
Second that!
Tightening wheel bearings hasbeen a constant job for me over the last
few months and i'm getting quicka t it now.
In Gabarone, Botswana and heading north for the Kalahari and Okavango
Delta as soon as the cruiser has a relatively big service.
Will beadding rearbearing check to the following work list.
- Tighten front left wheel bearing
- Grease UJ's etc
- Replace engine oil and all filters
- Check levels of diff oil, transfer and AT
- Get cracked wheel welded
- Replace water filter
- Fix air leak to front diff
Otherwise the cruiser is going OK - and am having ablast!
Good luck for now
