    Well if front drive shaft seems loose, that is a good starting point. Check it throughly off of truck and make sure transfer case is full of fresh fluid too.

    Noise

    The transfercase will make noise when in 4 wheel drive going down the road.
    It will sound like the gears are moving with the speed of the truck.Any other noise than that needs to be looked at.
    Also when turning in 4 wheel drive do not over turn the wheel like you can in 2 wheel drive or you'll feel the tires fighting to turn.

    Hey You Should defintly consider having the Transfer Case Serviced. It contains Fluid and can be cleaned out! I had a alittle noise from my 99 2500 when i put it in 4 wd. After I had Transfercase Serivce it went away!

    Not all do and some are noisier that others. My Borg Warner case in mine is quiet in high range. If the tranfer is causing the shaking it is beyond regular servicing too. Need to check drive shaft joints first then go from there when looking for the cause.

    The double cardan joint on that front shaft is kind of hard to get to the grease fittings. It may have been neglected because of that and be shot as Tarkus says.

    On my old GM trucks I always had to remove front drive shaft to make sure that joint was lubed properly. I would do it ever fall before winter set it. It was a pain but it was sure to get done that way too.

    There are two plugs on back of case, one to drain and one for the fill level. They use ATF fluid and do not just check it, change it. About 3 quarts will do it.

    You should have an NP208 in there with the W150, which takes Dexron II(current version III covers that). The W250 could have the 208 or a 205. 205 uses different fluid so if you have a 250 you need to know which T/case you have. W350 is the 205. NP205 can use GL-5 or Engine oil that meets at least an SF/CC classification. Consult your manual or a check chart for the proper viscosity for the temperature range you'll be operating in.
    Drain and fill plugs are found on the rear of the transfer case. Fill it till it comes to the bottom of the fill hole, just like a differential.
    Whichever you have I would drain and refill it.

    Sorry T. didn't see you beat me to it. I'm watchin the tube while I write. :waving:

    Never seen a 205 spec'ed for engine oil but I have for ATF fluid and gear oil. It is not likely to have a 205 as most quit using them in 81 and went with 208's to save weight and costs. Any ATF fluid you can find with work fine as long as it is of Dextron type.

    Yeah, I think Dodge was the one hold out on the 205 from what I heard. That info is from Chryslers 85 truck service manual. It says SAE 50 for over 32 degrees and SAE 30 fo under. I've only dealt with the 208 myself.

    Huh, interesting. Dodge was always a bit different. In 73 thru 79 when GM only used NP203 fulltime case with a automatic, Dodge used it automatic or stick.

    I always figured their oddities had something to do with their being used as military vehicles. Just a wild guess though.

    Hey gntbik, what have you found out so far, in regards to the front axle or drive shaft?

    Not so sure about that, I think they were more cost related, fewer parts to stock. Also the hubless front axle bearing cost less to make and was a pain to work on too.

    Glad you got it taken care of. Keep those greased if you got the greasable ones. There will be a small plug in the end of one of the caps of the joint. Some come with a checkball in a fitting that allows you to grease it with a needle or rubber tipped grease gun. Others will require replacing the plug with a grease zerk, greasing it, then replacing the zerk with the plug. Theres no room for a regular grease fitting to rotate. thus the plug.

    I was referring to axle joints,by the way. If that was driveshaft u-joint it would have the grease fittings.
    Don't run it on dry pavement. It will buck and be noisy if you do, and not good for the parts. You may also then have trouble getting it out of 4X afterwards. If so back up in an S pattern and it should free up.

    To the best of my knowledge, the NP205 was used in all W350s up until 93. The 208's were used in 1/2 and 3/4 tons...although I've seen a few 3/4 tons that were spec'd with the Dana 60F, and they also got the NP205.

    My 77 owners manual lists SAE 30wt for the NP203 as well. :)
