i was makin a real tight turn in the walmart parking lot (did you know supertech windshield washer fluid is now $2.50 for a gallon? wtf!) and the rearend locked up midway through the turn. anyway, i straightened it out, and backed up about 10 feet, cause sometimes that unlocks it. didnt help this time, so i was like "f**k it, i gotta get home." as i was driving out of the parking lot, i heard a loud CLANK!( /forums/images/graemlins/shocked.gif) and the rear end unlocked. im guessing my gov-lock is in its death-throes, so how long do yall think it has before it grenedes?/forums/images/graemlins/angryfire.gif and, on that note, if it goes, im gonna replace the whole rear axle with a 14BFF out of an '88+ truck. what gears did they come with? 4.10 and 3.73? 3.42 would be nice, i dont want to have to regear my frontend with that SAS a few months away.
