transfer case
I have a quick question about the transfer case in my truck. The case is leaking oil only when I drive it. Does a guy have to pull the transfer case to change the seals. Any info would be a great help thanks Garry

Mine is doing the same after a complete set of seals. My trans guy said to put a gob of silicone on the end of the output shaft and then put the driveline in place and this should help. Mine still leaks while driving and usually has a drop on the bottom of the rear seal. I'll be looking into this cuz I think its getting worse.

Yeah the silicone thing sounds like a coverup for more of a problem. Like old blues said a seal shouldn't wear out that easily, I would definetely inspect the shaft for wear. I've cone across the problem quite a bit with slip joints, torque converters, and other similar spots.

...unless the driveshaft yoke has a score/gouge/ nick !
BTW... tbtrans.com had the best prices (that I could find) for bearings, seals & forks. Bearings are US or Jap. Some vendors are 5 times higher (no affiliation, yada yada)....bruce

Mine leaked straight out of the factory, the dealer said "a little leakage is normal". Bull! The case only contains a very small amount of oil and can't stand being run low. I changed the seal myself and found the out put shaft had a scratch right where the seal rode. My guess is someone at the factory lays them down on a metal rack and scratches them. I polished it out with a fine stone and changed the seal, it's been OK the last 7 or so years.

check for cracks in the upper part of the housing. It is a common problem from what I hear. My case cracked at first it just leaked a little so I pulled it out and resealed it no change. It finally started leaking alot so i pulled it again cleaned it really well wiped the ouside down with talc powder and wiped it off I found a 4-5" crack in the top of the case. I needed the truck so I called the guys over at 1-800-mud-road around 7:00pm they were localish to atlanta they called me back the next morning and by noon I picked up a new rebuilt tcase.

Some yokes have a rubber washer inside yoke that is easy to overlook. Believe this is what guy recomended RTV to cure. Just a thought.
