How do you replace the rear end bearings in a 94 Nissan pickup, there is no rear cover to remove.. it has 200,000 miles, I figure its time. It is working ok, but has a clunk that seems to be getting worse, u-joints are ok, its definately in the rear, lots of rear end slop, any help would be appreciated. Thanks

TTT, anyone?? Will I have to just buy a whole new rear end to eliminate the clunk? Thanks..
