High pinion angle....Keeping the pinion bearings lubed

One important consideration when doing a suspension lift is achieving the proper driveline angle. In a short wheelbase vehicle like a CJ. That sometimes means having the pinion on the axle pointing up towards the Transfer Case at a pretty extreme angle.
The big problem is keeping the pinion bearing oiled. As it is setting way up out of the oil bath. I`ve seen more then one bearing get burnt up from lack of lubrication.
Here is what I did to my (YJ ) That might be of interest to you.
A radiator or engine oil catch can. (Summit, Jeg`s, Speedway etc) Connect it to the vent line on the axle all you need to do.
The can allows you to over fill the differential insuring that the pinion bearing gets lubed. The fluid heats up, expands and dumps into the can. As it cools it flows back down to the diff. Works on the principle of a radiator overflow tank.
With this I am able to run an extra 1.5 quarts.
