Engine/Transmission (1998.5 - 2002) Oil Spots every where after long trips

[Richterno1]

Every time i take a log trip with a trailer, at the end of the trip i notice little oil spots on the tailgate of the truck and on the front of the Box trailer. the bottom of the truck has a coat of oil to, where is it coming from the breather tube? the motor dose not burn oil.

235,000 miles on the motor

That "may be" from your transfer case.

Specifically the rear output shaft area on the TC.



If You look at your exhaust pipe by the T-case you may seem some burnt fluid on the pipe. Thats the a sign of the Transfer case rear output seal or slip yoke leaking.



I have had this problem since day one on my rig. I have replaced the seal many times but it still seems to work it's way out.



The best fix I found was removing the Driveshaft and filling the slip yoke end with RTV sealant and reinstalling. There is a small hole in the end of that slip yoke that seems to leak fluid. By doing this it greatly reduced the amount of fluid coming out of the T-case.



Good Luck and just remember that you have had a great rust inhibitor spraying the underside of your truck.

In smaller volume, I have had transfer case driveshaft seal leak for last four years. I keep an eye on fluid level and add fluid as needed every few months. Not worth trying to rebuild transfer case or keep replacing seals. The mess is a bit annoying, but I'm used to it now.
