2004 Jeep Wrangler ProblemsFront and Rear Differential Pinion Seal and Transfer Case Leaks
Leaks at the front and/or rear differential pinion seal and from the transfer case are common. Leakage from the transfer case normally occurs at the case-mating surfaces and require removal of the transfer case to reseal.
Water can leak near the A-pillar, at the front edge of the driver and passenger side doors. An improved seal is available.
Some models are susceptible to rear main oil seal failures in dirty or dusty conditions. As dirt and dust collect on the oil seal, the abrasion wears through the sealing surface. A spacer is used between the bell housing and engine that has a small slot in the 12 o'clock position. Filling this slot with RTV silicone and cleaning the seal area can help prevent damage to the seal.
