Fits:
1984-2001 Jeep Cherokee XJ
1987-1995 Jeep Wrangler YJ
1997-2006 Jeep Wrangler TJ
2004-2006 Jeep Wrangler TJ
2007-2010 Jeep Wrangler JK
2007-2010 Jeep Wrangler JK Unlimited
NOTE: Will Not Work with Wrangler models that have Vaccuum disconnect Two-piece axle shaft(Passenger side seal diameter does not fit XJ or YJ with two piece passenger side axle shafts)

I would recommend pulling the diff cover, replacing the axle seals, and inspecting the entire housing and cleaning all the debris out of the entire axle.
