I swapped to a trailblazer ss rear axle. This 3.42 axle had 102000 miles on it and was functioning perfectly. I've owned the vehicle since new. I changed the fluid at 60K and used Amsoil Severe Gear. Internals looked fantastic and it was really really clean in there. No leaks, SC vehicle it's whole life so there isn't much surface rust at all, nice and clean, stored indoors. No backing plates included. Located in Greenville, SC. $300...make an offer.
