changing transfer case and axle lube.

[ihookem]

I just got a quote on my transfer case rebuild. It will be about 1400 dollars. I never changed the fluid in it, most people don't. I can't say if I did I wouldn't need a rebuild but might have lasted longer cause the fluid was black. Just to remind my own kind it takes only a few qts. and 20 minutes to do. Mine takes 2.5 qts. of tranny fluid.

Thanks for the reminder, and your right. My Dodge is about do and I have been thinking about Amsoil products for the transmision, transfer case and differentials.
(Mine is a standard transmision, with a diesal engine.) I pull a heavy travel trailer with it and plow as well so I want as good as I can get. I switched my Harley to all Amsoil and noticed a big differance so now the truck.
Have any of you done this? I am interested in any input.

I just bought an NP208 for my Bronco.   the previous owner has the shifter secured in 2H with a coat hanger on the one that is in there, I'm guessing the shift forks are worn down.  I haven't even tried to see if it works and probably won't.  From what I've read when the shift forks go bad it pops out of what ever it is shifted into.  I'm gonna go through this one I bought and slap it in after I check it out on the bench.  I also bought a whole TTB Dana 44 to rebuild on the bench so I won't have to lay on my back and try to do all of that stuff.

All of  my stuff is pretty simple because it is a 1980, it would probably be a nightmare on a late model with all of the electronics and stuff.  Under the hood I have a straight six and  a one barrel carb. 

this is when I had the motor out to change the rear main seal and oil pan gasket.  I hate oil leaks...

Don't forget junkyards and craigslist. It's relatively easy to find transfer cases at reasonable prices in good working order. Also a 4x4 shop with a good reputation is a plus as well. I had a transmission kicking out of high gear. Bought an engine trans and transfer for $175. Had the shop install the trans, transfer and also pulled the clutch for them to install as well. It ended up being $150 labor. Plus I have an extra transfer and engine to boot. May save you a bit of money to go with a used one. Mine came out of a 61 model, so there's no such thing as one sitting up too long.

Good idea bugflipper. It's too late now though. Next time though. GHREENRIVERS, I use Amsoil in my tranny and fro oil. I change oil very seldom and my tranny and filter every 35k. I use used oil anylises to test my oil. It's 25 buck though. This is my last time testing  it though. I went 46k mi. last time on my oil. I change the Amsoil filter every 17-20k. After 46k I got my oil tested and they said it was still good oil but said to test in 7 k mi. so I changed it anyway. It is hard to believe oil can last that long but it does. I won't bother going that long any more though. It starts very well in winter, cause of this I think my motor will last a bit longer. I get 1% better fuel mileage, or .2 mi. per gal. more. It's not much but this means I use 24.5 gal instead of 25 gal. and that half gallon a week savings 25 gal. a year or 100 bucks so it pays off.

My brother is a shop foreman in a large national trucking company and they test the oil in there rigs and change it between 25-50k miles depending on what deposits are found in the oil, but they change the filters every 5k and fuel filters every 3k miles. He says that the rebuilds are far and few between and have saved the company money. I run full synthetic in my gasoline engine and change the filters every 2500 oil every 8k it has 113k on it with no metal in the oil. I change the transmission fluid and filter every 30k knock on wood so far no problems!

Thanks for the responces guys! I had sent Cummings an email when the engine was nearly new asking about there preferances. They did respond and told me that because of the hydrocarbons suspended in the oil they recomended staying with Chryslers maintenance schedule and oil. I have done that with the engine as it does sound reasonable. But the drive train is differant. Oil is cheap, engines are not!
