I'm just throwing this out there out of curiosity. Does anyone make a rubber boot to use with or instead of the large swivel seal? I have read that one good submerging of the knuckle in water will let enough water past the swivel to soon trash the lower kingpin bearing. I hunt in the Carpathian mountains in Romania, many times a year having to ford shallow creeks. My Zook is only 2 years old and I just shimmed the kingpin bearings and found evidence of water intrusion in the knuckle. Seems to me a boot would be a much better solution to this problem and not knowing any better, I would think these would sell well, even at twice the price of the seal. If a boot is out of the question, has anyone drilled and tapped (for a plug screw) a drain hole in the bottom of the axle end, not swiped by the seal, that can be used to drain water after a good dunking? A boot would be better but it would seem to at least help to get any accumulated water out. What do you guys think? RJ

If you are frequently submerging the axlehousing then periodic disassembly to clean and regrease the birfield joint will be required.
If you are getting enough water in the knuckle for it to run out via a drain hole you have a very significant problem. I’ve only seen evidence of water- nowhere near enough to run out an open drain.
A boot would be a complex piece- it would need to be split to install, and there’s not a lot of room to work with. There’s a high likelihood it would have a short life or be ineffective. Have a look at the boots available for 2.5 tonne Rockwell axles for ideas.
Consider too that at least some of the water comes from condensation, not necessarily ingress.
The key issue is periodic disassembly and regreasing will still be required. Water will always get in.

Gwagensteve, yes water will always get in with the factory type seals. I have found a company in your own country that makes the exact thing that I am talking about for the '78/'79 Toyota Land cruiser. That rig has the same type of seal that the Jimny does from the factory. If I can find out where to buy at least one of these, I will see if I can adapt it to the Jimny. The name of the company is: Gearing Dynamics in Victoria. Here is the link. http://www.gearingdynamics.com.au/Split ... -80-Series Let me know what you think. Thanks, RJ

Yes, that’s exactly the design you’d need. The land cruiser swivel iis much larger though so adapting it to a Jimny won’t be feasible.
However, read carefully about what this boot does. It does not claim to improve the seal of the steering knuckle to the swivel housing, that’s the job of the wiper seal. It prevents corrosion of the swivel ball in extremely destructive mine environments- where the vehicles spend their whole life in a gritty, mineral rich, wet environment. This will rapidly corrode the bare steel of the swivel housing, causing the stock seal to fail. As the swivel housing is neither replaceable or chrome plated like an older Land Rover, repair requires axlehousing replacement.
No claim to improved sealing is made over the stock wiper seal.
If your car is only 2 years old, the swivel housings should still be in good condition.
