Hi Everyone, this is my first post so please bare with me.
Looks like my steering knuckle seals are gone so I figure I may as well replace bearings and all seals with a rebuild kit if I am going to pull it all apart, I'll do both sides. There are several kits online and they range in price from $80 - $200 for what looks like the same components. I assume the cheaper ones have chinese bearings but most say Koyo or Timkin. Just wondering if anyone has used a kit and what they would recommend as I want to use quality parts that will last. Thanks for any reply's and advise. Cheers

Thanks, saw them online, they seem to be the most expensive. I'll give them a call and try to find out if their product is different to others at a higher cost. Cheers

Are you going to do the work? Buy a bag of rags. You really need to inspect before buying parts, as it could just be a blocked diff breather, or over full with diff oil. Do the cv's click on turns? Wear there is the number 1 cause of premature seal wear and subsequent leak. Fixing the leak can get expensive. The axle seal can be bought by itself, the better quality ones are dearer. CV's are best bought from repco for good quality. The best swivel hub bearing is koyo (factory bearings) as they have 1 extra roller compared to other brands (spread the load better) I would start by buying 2 new axle seals from newcastle, and swap your cv's left to right, so they run on the unworn side when moving forward. (if your cruiser is constant 4wd and they are clicking) new grease for the swivels and cv's and new brake disc pads if oil has got onto them. and you should be good for many years.
b4 you bag me out, walk a mile in my shoes, then your a mile away and have my shoes :)

Thx Dozer, she’s done 360000 kms and I doubt the bearings or anything has been changed. It’s leaking grease onto the large ball joint so the rear seals are shot. I’m doing the Simpson in a couple of months and don’t want to stress about it so thinking for a couple of hundred dollars and a days work I can do it and not stress on the road. There’s no noise at all, so do you think I just need to clean it all out, regrease and replace seals?

Chris - At 360,000kms, I would be replacing all the wearing components. It's cheap insurance to put in new wheel bearings, new bushings, and new CV's.

The front axle cops a hiding on 4WD's. It does 80% of the braking, hits all the potholes and rocks first, does all the steering, and takes a lot of the drive power when bush-bashing.
The front wheel hubs have to absorb a lot of braking heat. They have to cope with cold water immersion, when you're fording creeks with water in them.

A skilled mechanic can examine roller bearings and make a judgement call on whether to put them back. In general, you only put back low-km bearings.

I've seen Mack Trucks state in their manuals, that if their diff bearings have done less than 200,000 miles (320,000kms) and show no sign of damage, you can put them back.

But we're talking Landcruisers here, not Mack trucks, and at 360,000kms, the wheel bearings on the front of a Landcruiser, rate as "well-worn", at best.

The spindle bearing bushes are critical components that ensure steering and drive alignment, and when these are worn, you will get front-end wheel shimmy.
It is best to replace these at a minimum.

The wheel bearings are not a major cost in the overall scheme of things, but they are critical components. You would be best advised to replace them.

Be aware that the preload on taper roller bearings is critical for long life and best performance.
Take note of the manufacturers requirements and instructions for bearing preload.

Cheers, Ron.

Terrain tamer do a kit make sure you get the kit with the bronze spindle bearing bush.
Terrain tamer

The general consensus is use genuine Toyota axle seals ,even though you will get seals in the kit , use Toyota axle seals the rest off the parts/seals will be ok.

And what Dozer said , plenty of rags and solvent / if find mineral turps good.
a few videos on youtube on how too. cant get the links too work .
Youtube (80 series swivel hub rebuild )

Cheers Rob

I only ever made one mistake

there is a really good you tube video of simon dangerfield from cms doing a rebuild on a 75 cruiser front end. he uses and sells terrain tamer parts... give it a watch and see how its done and also some of the tools needed... and get a box of latex gloves to go with your rags grab a tarp to put down on the concrete and also an old sheet to catch any oil or grease that may come out.

Hi Chris,

I found it best to use Terrain Tamer parts, they use koyo bearings which are the best.

Make sure you change the spindles or it will still leak.

Make sure you change the trunion bearings while you are in there. A small amount of money for alot of benefit. Your steering will improve out of sight.
