When I did my front u-joints in mine when I first bought it, the passenger side leaked like crazy the next day. So I took it all apart again (thanks antisieze
and cleaned out the tube and seal with a rag taped to a broom stick, and cleaned the axle. Then lubed the axle seal and axle and put it all back together. Hasen't leaked since and that was two years ago to a stock jeep that had never even seen a gravel road before I bought it.
I'd say do what I did and clean the tube, seal, and axle real good. Be real careful putting the axle back in and it might work out fine. If the axle is grovved bad where the seal rides then replace it or put a speedy sleeve on it.
