anoise & tremble problam

a 1990 dodge dakota, 6 cyl,3 speed auto. it started with a real loud roar, then it started to tremble, not shake. i raised the rear end & put it thru the gears, didn't see or hear anything. the mech cant pinpoint it. i thought maybe trans so changed oil & filter, didn't see anything in oil. now think maybe drive shaft, it looked okey. dont want to break down while away from home, any thoughts.

is it still making noise or has the noise went away and you just have a tremble/vibration?
you can grab the driveshaft and check for play at the u joints by attempting to move shaft side to side and up and down shouldnt have any noticable play.dont see how spraying wd 40 on a u joint would help to tell you they are bad.

question

Is your truck a one piece driveshaft or does it have a center bearing?

thanks for replies, the driveshaft is one peice, what it is, is very niosy all the time, more like a howl. the vibrqation is up to about 55mph. something i didn't mention is, when the rear end was up of the ground the driver side rear didn't turn. i have checked the drive shaft several times, looks & feels ok. it does clunk & does squeek while driving, the noise is so loud that i cant hear if it is squeeking or not. the trans goes thru its gears good. thanks for the answers. will try the wd40, you never know

its not uncommon for the differential to howl if the ring and pinion teeth are meshing together incorrectly it usually only accurs on acceleration or deceleration, so if the noise only occurs at deceleration or only at acceleration then it is probably coming from the rear differential.

Did you check the fluid in the rear end.
