I recently purchased my first Jeep, a 1985 Scrambler. The rear axle/housing is an AMC 20 and is leaking quite a bit at the passenger hub. I've tried to fix it and have it fixed but it continues to leak. Does anyone have any suggestions to fix it? If not, what replacement axles are worth looking into? I don't plan to do any serious off-roading in the Jeep. Please let me know if you need any further information and thanks in advance for your help.
