  1. Rear Diff replacment

    Looking for some insight, I have a 2018 JL Jeep wrangler sport 2 door. 23,000 miles well taken care of and maintained (no oftermarket mods). In 10/20 I had to replace the rear differential at 20,000 miles. After that i constantly heard a low grinding noise when driving, took it back to the...
  2. (Question) Differential / Transfer Case Fluid Change

    Long Story Short, I'm getting a new transmission under warranty. That Jeep dealership called me that they needed to do a Differential/transfer case fluid change.

  7. Limited Slip Differential vs. Posi-Traction

    The other day I turned off traction control and did a burn out and I noticed I had to sets of tire marks left on the road. I don't have a LSD so I was wondering how this was possible. I remember on old RWD cars that some had posi-traction. Do Jeeps?
