I run a non Grand National rear, Bicknell calls it a mini 3/4 ton. I have the inner axle seals. Over the winter I had the left rear underslung lowered, now this year I am filling the left side tube and hub with Gear Oil. Am I the only person doing this?? Is the inner seal shot or do I need to do something so left rear doesn't hang down when the car is on jack stands?

On our 9" which is a mini 5 hub, GN's are about the same deal, just the snouts are shorter. Anyway we run a axle seal on the right side tube only.

I have been thinking about running axles seals on both sides to avoid the problem your talking about.

Also i have heard that if you do not run seals you need to pack your bearings with grease to stop the leaks. Plus if you do run seals you need to pack the bearings with grease to keep them lubricated. So i figure i will run dual seals, and pack the bearings per usual.

Pull the hog head out and see if it has dual seals, if its only got one on the right hand side, you can put one in the left, or just leave the LR jack a little bit higher than the right and that should keep it from leaking while sitting in the shop.

My car will leak while sitting on the ground, due to the stagger, so thats why i was thiking of running dual seals.

I recently also noticed leaking as well. I just recenetly switched to synthtic lube and figure that was the main reason. I run 3 quarts of lube. Is that too much? I have heard as much as a gallon from some gear manufacturers.

It has the inner seals on both sides. I think it just goes between the seal and the axle when the car is on jackstands. I run a gallon of oil and I think the oil level is high enough that when the rear is tilted it is up over the seal. Its just a pain because the oil ends up in the hub and washing out the grease.

we run seals in both tubes and grease the bearings. I cant imagine not greasing the bearings because I would think the LR would hardly ever get lubed, on the track anyway.
