  • has 4wd lift spindles (relevant to suspension jobs, brake jobs, etc.)

Current concerns

  • engine: valves sound to be running tight, likely need adjustment, according to John Najem (possible wontfix)
  • engine: intake boot is cracked underneath the clamp (likely needs replaced)
  • cooling: slow leaks?
  • steering: slow leaks?
  • driveline:
    • transmission whine in 1st gear
    • possible whine from rear diff
    • possible transmission fluid leak? (saw some fluid on bottom of bell housing & dripping off of oil pan)
    • likely needs new diff bearings and seals, possibly rebuild
  • AC broken (deferred, likely needs conversion kit)
  • passenger window switch not working
  • paint blemishes (likely needs paintjob, current paintjob seems cheap)
  • occasional rear-end shake/shudder when braking from highway speeds
  • weatherproof/undercoat to protect frame and underbody
