I found out the hard way that I had a pinion seal leak in my 96 Burb and it is howling like no tomorrow. So I am putting a 9.5". I am keeping the differential and brakes (backing plates), but the empty housing and axle shafts are up for sale. All are in good shape, just the ring and pinion bit it. $150 or best offter. I am in SE WI, and travel to Chicago NW Suburbs for work daily. (it is available as soon as I get it out) This axle fits the 88-99 OBS GMC/Chevy K1500 trucks. email me at nhzlv (a_t) pensys dot com (remove the (a_t) and spaces and replace with @ And the space dot space com with .com
