Is there a right and wrong way to lubricate the wheel hubs?

After replacing the brakes I noticed some leakage from the front hub. I figured I'd top off the fluid but I'm not sure if its a separate sealed system or if it gets its oil from the diff.

I noticed the square head bolt that I assume is the full plug. Do I simply top it off the way I would the diff with the same gear oil?

Very close to getting this rig back on the road after two months of working on it. Thanks to all for the help!

Drain it on both sides. Take the square plug out. Full each side with a packet of "one shot" grease. If it still leaks, you need to investigate further. Is the wheel bearing hub nut thing properly tightened? Where is the leak exactly?

I think so. I followed the online video tutorial. Tighten all the way then back off a quarter turn. The wheel rotates freely. It's wheeling a small amount from, what looks to be, the bottom of the ball.

Replace with one shot grease and that should go away.

So grease and not gear oil?

------ Follow up post added June 29th, 2013 12:47 PM ------

Btw I just replaced the bearings and repacked them with grease. Sorry, I'm just confused about pumping grease through the fill plug?

Thanks again

What you are filling is for the cv joints. It is separate from the bearings. The bearing should be packed with grease.

The cv joints can have gear oil or the special land rover grease. It is thin and intended to help stop leaks. Personally I would suggest gear oil. It can be drained and it lets you know when a seal is bad.

A small bit of leakage from the swivel seal is normal and I would not worry about it.

Gear oil versus "One Shot" grease from Land Rover has been debated forever.

The only reason Land Rover recommended the One Shot grease was because customers were complaining that their $40,000 SUVs constantly dripped oil and stained fancy driveways/garages.

Personally, I run the One Shot grease in my clean truck that doesn't do water crossings and muddy stuff.

Gear oil in the truck that gets wet and muddy; so it can be drained and changed.

BTW, isn't the Defender just like the Range Rover in that it has a drain hole, a level check hole at the halfway point, and the fill hole at the top?

Defender has a drain hole at the bottom and a fill hole near the top. Fill until oil comes out - we ain't fancy.

That's what I thought...only difference is the level check plug on the RR is a 7mm square sided plug.

FWIW, I overfill mine in anticipation of future loss.

If you overfill the swivell balls and the seals are bad the oil will go to the diff...

But isn't that the same gear oil anyway?

If you plan on going through water, use gear oil and drain regularly. The swivel balls aren't sealed at the top against water ingress. Really strange oversight on the part of the designers, but the swivel ball seal doesn't seal at the top of the knuckle.

This was really helpful! Thanks everyone for your feedback. I managed to get them topped off to the right level. The level check was gunked up and after leaning it up with a small pick I was able to get all the excess drained out successfully.

All I noticed was the incredibly un-dirty and un-rusty looking axle and swivel housing. That looks almost as if it was driven from the dealer to a garage, never again to be moved.

Ah, that explains it
