Buying Tips for 2017 Jeep Wrangler (JK)

  • Inspect the chassis frame and door hinges for rust; Jeep used poor quality paint on the hinges, which frequently bubble and corrode.
  • Check the underneath for severe off-road damage to the diff covers, exhaust, and suspension control arms.
  • Test for "Death Wobble" (severe steering wheel shaking after hitting a bump at speed); this indicates worn track bars, ball joints, or steering dampers.
  • Verify the operation of the manual 4WD transfer case lever; it should engage 4H and 4L positively, though it requires a firm pull.
  • Check the removable hardtop panels ("Freedom Top") for leaks around the seals, which frequently drip onto the front seats.
  • Look for electrical faults in the TIPM (Totally Integrated Power Module), which can cause random issues with lights, horn, and wipers.
