moans in 4wheel drive

[97 crewcab]

Hi all,
Ok heres the skinny, 97 psd with dana 50 ifs. Moans in 4x4 either hi or low. 2wd is fine no sound or anything. when in four wheel under load no sound, when coasting or braking sounds like truck is an 95 year old arthritic man geting up from a nap, groans and moans like crazy! sounds seems to be coming from the front left side of truck, just replaced all the bearings and seals and ujoints on that side. Had a friend of mine at les schwab rebuild the front end with new ball joints and a drop pitman arm (truck has a 4" lift). I have everything to rebuild all the u joints and bearings and seals but, if I don't have to do them then I want to save them. Any help on this would be great, we are in about 2 foot of snow in Northern california, yes, cali gets snow too. Plus we are scheduled to get more this week and might need it to get out to get kiddos to school. PLEASE HELP!



"No animals were harmed in the cursing of the rebuild of this front end, few dings in the wrenches and knuckles, but that is what they are for."

That sounds like the prob im having with my 4wd. I packed the wheel bearings, replaced the spindle bearings and replaced the locked up U joints with no change. Im thinkin its the output shaft bearing in the transfer case but really havent looked into it much yet its been to cold.

The double cardan u-joint at the t-case likes to fail. Mine did. At first they moan, then they start to pop really bad. You have to get 2 u-joints and the centering yoke, and if you let it go too long you end up buying a driveshaft.

is that the first U joint from the transfer case ? What do you mean the centering yoke ?
