- 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
