Cool Swivel Ball Fluid Change Help Please

I was hoping that someone could refer me to a useful web page or site that provided directions on changinng the fluid in the swivel ball housings. I've changed every other fluid in my d-90, but I'm just not certain of the right fluid and procedure for this task. Also, I've been told that my '84 Defender had newer/different axles than the ones it left the factory with from the person who sold the truck to me. I don't know if this will affect the procedure. The axles look very similar to any d-90 axles I've seen, but is there any way to be certain which ones they are? I'm also wondering about the axles as I will eventually come up on my first brake job. How to determine which pads to buy, as the axles may not be original, will be important. Any help on either or all of these issues would be appreciated.

The rave CD will show where the all the plugs are. From what I understood, If it didn't come from the factory with it, One shot grease, available at your local dealer, will be the last time you have to replace it. I thought I read something about a sticker on the radiator shroud or a yellow paint marker swipe on the drain plugs indicating one shot was applied. I don't think they did it in '84 but you are saying your axles aren't factory so maybe it was done. Maybe someone could validate what Im saying since I'm kind of a noob at this myself.


better yet, do a search for one shot grease and start reading. I was gonna post you a couple of links but there is so much that applies to your question you are probably better off reading it yourself.
hope this helps!

This is where I'm supposed to write something witty and funny; or something.

Mike, you can determine if you have oil (90W) or the one shot grease 2 ways

1. If the swivel balls leak or look wet it's likely got oil
2. If you open both the drain and filler plug and peer inside it should become clear. If it's oil, you should have oil come out.

IMO, its safe to add oil in either case but I'm not 100% sure.

If you turn the wheel to the outside (so left when working on the left, right when working on the right) the inner portion of the swivel ball moves aside opening up the fill hole which makes it easier to both see in as well as fill.
