Just the drivers side brake. Since I had been planning to swap in the 14b, I was ignoring the stuck caliper. Now it would need, at a minimum, a caliper, rotor and a set of pads. Other than that, it is fine. I probably let it go for too long, but I was planning to swap it out anywho. I bought the truck with 64,000 miles or so, I never abused it and never had any trouble with it. I also have never pulled the cover off. This axle is coming out sometime in the next week or so though.
I'd part with it for dirt cheap, but if it was me looking for one, I'd find one from a zr2 and get the bigger differential.
