First time in 4WD now i have noises....
okay, here it goes...
So, i bought my D on the 7th of this month.. all was well till we had a snow storm and i had to use 4wd.. the truck started making a humming noise it would start when i would reach about 20mph and stop when i came to a stop. i first thought was it was stuck in 4x4 but, i have conformation that im in 2wd. then i noticed that this humming noise would change to a chattering when i would let off the gas. I thought with my past exp. that i could be the u-joints so i decided that since they where sorta cheap and i had a press tool that i would replace all the joints... well, no luck still have the noise... i have also checked the gear oil in both axles and they where down a little so i topped them off ran it a little to see if it might go away after the oil was added but, still no cookies..lol I have tried to pin point where the noise was coming from so i could maybe find the issue that way but, its hard to tell.. i kinda sounds like its coming from the left rear but, it also sometimes sounds like the right front... so im at a loss here so i thought i would throw it out here and see if someone might have a idea...
it's a 1998 5.2l btw

okay, i tried coasting down a hill with both tranny and tcase in N... noise is still there so i went back to the top of the hill and tried coasting down with the tcase in 2wd and the tranny in N.. noise still there...so, i had a friend drive the truck while i sat in the back seat and it appears (99.9% sure) to be coming from the rear axle.. since i have no clue how the rear axle works on a dodge, whats in there to fail?? wheel bearing??

id think it almost have to be.. the u joints where already replaced.... also i dunno if i mentioned it but the noise seems to be coming from the rear drivers side..

Don't rule out the u-joints. You wouldn't believe how common it is for those things to already be bad when you're driving them home from the parts store.
