i have a 14bff on my jimmy. it has an atron disc brake conversion on it, and i run 32" tires. ever since i have had it the thing has had leaky rear axle seals. the guy i bought it from replaced them both, and i replaced them both. the passenger side leaked instantly, and the drivers side took a while but is leaking again. i used a speedi sleve on hte passenger side but it still leaks. any ideas?
