Subject: [RR] rear axle bearing numbers

Anyone know the specs on the rear axle bearings on a '92 County? I'm hoping
to be able to get new ones at the local bearing place. The work is being
done at a garage so I can't really have them pulled and then take the old
bearing in for a direct comparison while the truck sits on the hoist. Any
words of wisdom or experience would be greatly appreciated.

Both front and rear wheel bearings are Timken set #37
(available at local parts store for about $10 each).
This bearing set is made up of Timken #LM603049 and
LM603011. Land Rover-packaged Timkens are about $30
or so per hub.

I've heard this before concerning the RTC3511. If it's a RRC item, it

pre-dates any NAS Rangie. Great Basin Rovers recommends this seal, but they

note there is an issue with the seal. Does this just mean you need to make

sure you drive the seal all the way in?

Tech Tip: we recommend using RTC3511 hub seals even if you don't eliminate

the axle case seal. This is a double lip seal and a vast improvement over

the seal currently specified by Land Rover. When Land Rover added the axle

case seal they used a much less effective hub seal because the wheel bearing

now specified only requires wheel bearing grease for the bearings. Wheel

bearing grease is very easy to seal in because it doesn't go anywhere ie: it

doesn't flow. The problem is the current specified seal isn't very effective

at sealing things out such as water - hence the risk premature of wheel

bearing failure! When installing RTC3511 hub seals, recess them 3mm into the

hub or you will get a false reading on your wheel bearing preload.
