I have a 2000 dodge ram 1500 4wd 360. Im experiencing a vibration when at highway speeds and letting off the gas. it seems to be coming from the transfer case. There also seems to be excess play in the rear shaft of the transfer case when under the truck. Is this a bearing problem and if so is it an easy fix? Thanks in advance.
Is the truck lifted too? It could be several different things, tranny rubber bushing mount is loose or broken, driveshaft out of balance or tires out of balance, possibly mud stuck on the back side of 1 rim??? Tire could have a broken steel belt. Bad wheel bearings or front end components or even bad rear axle. Good luck!
The vibration is coming from the driveshaft for sure. The vibration is felt when applying gas and letting off. When i get under the truck and shake the driveshaft near the transfercase it seems loose. The rearend is not the problem as i just had it rebuilt.
Hows the tranny mount and driveshafts u-joints? Try a quick test, lift the tires off the ground and spin them and notice where its coming from exactly or even to see something loose like maybe your pinion nut at the rear axle. Manually spin a tire and notice if the driveshaft is warped or if someone has stuck on a stick on wheel balancing weight on your driveshaft, there could be a small metal piece spot welded on it from the factory for a perfect balance. You never know if somebody is playing a joke on you by doing that... [img]images/graemlins/cussing.gif[/img]
