Dorman - OE Solutions Drive Shaft P/N:976-780
Dorman 976-185 rear drive shaft for the 2011-2012 Ram 3500 carries engine torque from the transmission to the rear axle. It is a replacement for a worn or damaged shaft.
A drive shaft that is worn or out of balance can show up as vibration at speed, a clunk when shifting or accelerating, or squeaking from the joints. A worn U-joint, a loose pinion flange or unbalanced tires can be behind these signs too, so find the cause before buying.
This drive shaft is a direct-fit replacement for the 2011-2012 Ram 3500 in the rear position.
