Well this is round 5 of replacing all the u joints in both the front and rear driveshafts, I am even using the best spicer greasable u joints available. Still tearing up. Good choice of design dodge..

Repair shop said the 3500 uses different ones than the 2500. The carrier bearing is almost $300 alone. Total cost = 1 day in the shop and 3 heavy duty U-Joints and 1 heavy duty carrier bearing...$700 Other option....1 match free, gallon of gas $2 = no more money into this truck! Well over $8k in repairs over the last 5 months...no warranty available since I have too many miles on it now...Stay clear of Dodge Trucks!
