IDEA TO PREVENT BEARING FAILURES COMMENTS PLEASE

I’m sick of changing King pin & wheel bearings in my Jimny.
The other day I had an idea. The bearings general fail as a result of ingress of water / mud into the axle housing probably through the swivel seal.
Since I have long changed to manual hubs, my idea was to introduce a positive pressure down the 4 redundant pipes for the vacuum hubs thus preventing the water getting in.
At first I thought about tapping into the exhaust manifold but I’ve since gone off this idea due to corrosive nature of exhaust fumes.
So I’m currently thinking about a small pump such as windscreen washer pump or if this is not man enough a small compressor. This could be operated by a switch on the dash before entering water. Due to time constraints I probably never get around to trying this but what do you guys think?

The theory is sound. why not give it a go it can't do any harm.

I may have a look at work for the bits needed because iv googled it all including positive pressures etc and seems to work well

Sounds a fair idea. I've been wondering if it might be possible to use rubber TWO swivel seals under the metal ring per side! Crazy or might it be practicle??

I think you and I are working to the same goal. We ought to put our heads together,.

Pressure from the crank case (rocker cover) might be sufficient?

I've made my own gaiters for all kinds of things like this out of leather, 'stitched' with small cable ties. I bought a sheet of soft leather on eBay which is easy to cut and has made a dozen or so gaiters of one sort or another. If you rub grease into the surface before fitting, it waterproofs it. Then fill the interior with grease to lubricate the joint. It's actually the grease providing the waterproofing and the gaiter to stop the grease escaping.

just a thought could you not do something with the vacum pump. as there must be an exhaust of some kind on it

hi my swiwl seal is starting to leak agen can i just buy the rubber seal and cv seal or do i have to buy the swiwl seal kit

or can i make my own swiwl seal lol lol

thought it was

when i frist got my jimny the king pins had gone and was leaking all over the road but when i got new king pins and bearings and swiwl seal from j&j motors thay didnt give that axle seal that was one year ago and now its strating to leak agen

thay done me for £160 for that lot and no little axle seal

would my swiwl seal be ok though guys and just do the little axle seal
