I have a 95 Discovery. I am considering taking out the seals in my front axle and getting the flanges from GBR and going to gear oil all the way through. The main reason is that I need to replace my hub seals anyway, so while in there I would like to go to as simple and reliable a system as possible. Also, I would like to be able to easily check/change my lube (in the bearings and swivel ball).

I am not a big fan of the one-shot grease idea as I like to change the lube frequently (especially after wading).

What seals would I need to remove? Which would I keep?

Anyone have any insight or experience?

I personally run with no inner/axle seals in the rear but I kept them in the front. This seal is on the inside of the stub axle/spindle for both the front and rear.

In the front there is another inner seal to keep the gear oil seperate from the swivels. My reasoning behind keeping the inner seal in the front is because of the thought that by articulating the axle all the gear oil(or most of it) could get stuck in one side swivel and starve the other side or the ring and pinion of oil.

There is a seal in the front to keep the gear oil out of the wheel bearings from the swivel ball so if you remove it and just fill the swivels with oil, it will also lubricate the wheel bearings*but* I still grease the bearings upon reassembly.

Whenever you change the outer seal that is on the inside of the brake rotor you should get the double lip seals.
