They are the same set up but I don't think there is the plug you can remove to pump in more grease. Undo one of the bolts on the bottom king pin bearing cap and see if anything comes out andnmaybe pump grease in there.

Otherwise a strip down job.

Best thing would be to strip them down completely. Check all the bearings at the same time.

You might find that the corrosion is due to the vehicle being driven in salt water at some time of its life.

You can do the job yourself if you are so inclined....just time consuming.

Are you just looking at teh outside? My old GQ which had worked pretty hard most of its life had the same "problem" you are talking about.

I have highlighted the word problem because they never were. Across the paddock, up the west coast, Flinders Ranges, NW Victoria, Blue Mountains it was working hard under me too. But I never had a problem with the hubs.

Then before going to Cape York I got talked into a "pre trip check" which was carried out by a well respected specialist 4x4 workshop. "Those hubs look a bit ordinary." says the mechanic. "Well fix them." says I reaching into my pocket a little further.

I set off to Cape York confident that my GQ was in fine shape. Then on the beach at the Pennyfarther river what starts to slip. You guessed it the front hubs.

When I got home I asked around a bit and could not find anyone who had had trouble with the hubs on a GQ. My professionally serviced hubs continued to slip and I eventually replaced them with a pair of dry corroded looking ones from a wreck. Never had a problem again. I regularly checked wheel bearings and had to remove the hubs for that job so I was regularly looking at them. The outside always looked ugly but the inside is what makes them work.

I would have a look at them and keep an eye on them. I would give them a hard time close to home but I would be suprised if they caused a problem.

Now I am not a mechanic and I have not done an exhaustive study of Nisssan hubs but that is my experience, for what its worth.

Sounds like I should strip them down just to be safe. I'll need to order a whole lot of new seals I suppose...

Thanks for the feedback, Jim

If your talking about the large 'balls' that are the swivels inside the discs looking from the front of the truck, they arent ment to have oil/grease on them from the outside - if they do you have a blown seal.. :)
