    Wow what a great explanation , I did not know that about this truck. I had the transfer case rebuilt about 8 years ago and was surprised that the seal is already leaking. I was going to start with replacing this seal because it is leaking but I will check out your idea prior. What concerns me...

    PureHybrid I am not sure ? I read somewhere that you should also change the bushing as well, Heck I am not even going to pull the transfer case to replace the seal, Perhaps I misunderstood what they were talking about. They probably talking about the tool to install the new seal. I was going to...

    Thanks 2004LB7 It is pouring rain today in So Cal , I am hoping the rain stops tomorrow so I can check the oil level in the transfer case, Regardless I am going to have to replace the seal, I understand there is also a bushing that should be replaced at the same time.

    I am going to pull the plug tomorrow and see how much oil is in there, I can see that the seal is leaking, could be real dry. I know that that there is what i believe is a cable or it could be a wire that runs from the transmission into the differential, Does that wire/cable activate the tow...

    Thanks for asking, I believe you are talking about how the pump rubs a hole in the case??. I did have to do that a couple years back, I installed a safe guard metal sleeve inside to keep it from rubbing a hole in the case.

    ok cool, What fluid is recommended ? I can google that as well. Have you ever heard one that is low on fluid ??, This thing sounded like a steering fluid pump running out of fluid , But only when i let off the throttle . Thanks for the reply

    I recently had the entire top end on my motor rebuilt, You name it I replaced it, As you all know it gets expensive and I could not afford a new truck. I just got my truck back from the shop after the rebuild and put about 400 miles on it and it runs perfect and sounds great. I decided to haul...
