Hey guys. I just moved here from Austin, TX. Drove my 08 Xterra Offroad hauling a trailer the whole way. The Xterra only has a few mods. Daystar lift, Shrockworks front bumper and skid, HID headlights, 18" wheels wrapped in 33" Nitto's. I've run through a little mud and done a touch of rock crawling with it. I did spring a differential leak from the pinion seal on the way here. Any one have any experience with that? I don't have any air tools with me and it seems like all the stealership's service departments have terrible reviews. Trying to figure out what to do. Any local advice?
