Two problems related to driveshaft have been reported for the 2006 Dodge Ram 3500. The most recently reported issues are listed below.
A possible mechanical malfunction in the front drive shaft/front suspension possibly caused the vehicle to veer into oncoming traffic and cause a fatality crash.
I was driving home started hearing what sounded like grinding and some vibration, I stopped and looked all over under the hood and under the truck and could not find anything, I continued a few miles and the noise disappeared, the next day I left and the noise started up again about 30 miles from home on the freeway, I was doing about 70 mph,, when I pulled off to side of the highway, the noise disappeared before I stopped to look it over again, I turned around and went home and heard nothing at all, got under the truck and didn't see nothing, the next day it happened again doing about 55mph,this time it was getting load, I made it back home, looked over and between the left front wheel and noticed something wrong with the front driveshaft, when I got under the truck ,I noticed the front shaft coming out of the front differential didn't look right, I looked closer and found that the front yoke coming out of the differential has a round ring rock guard from what I have been told is pressed onto the yoke shaft to protect the seal, and it has weights on it also to balance the shaft, the ring or rock guard has come loose and was spinning on the shaft causing damage to the differential housing and to the oil seal, it did some pretty good grinding damage to the housing, I have taken it to a driveshaft repair place, they said the will need to rebuild the front differential to check for other damage to the bearings and so, as it looks now the mechanic says he doesn't know if he can save the differential housing with all the damage, as for now I cant afford to fix it, the rng or rock guard for now is getting held back from the housing with electrical tape, I know it sounds bad but currently being cut from my job with no income, I have no other choice but to drive it the way it is ,it is my only means of transportation.
