The rear end components have been replaced (3) times. Original failed, second failed, third failed. Have 110000 miles on truck. Have replaced fluids every 15000 miles and have added necessary additive. Never towed until (3) years ago. Dodge no help. I plan to replace entire axle with rebuild. Can a heavier axle fit the 1500 4x4 vice the smaller one they put in?

    Anything CAN be done! It may bolt right up just have to get the same gear ratio and the rear drive shaft plus u-joint yoke may be different... but that's no prblem! I really don't know! Good question! Google it or maybe even search youtube! They have some 'different' stuff there!

    Thanks. The points you made are what I am looking for. I can't seem to get an answer if it will bolt right in, and what it might take. Gear ratio should not be a problem. The u-joint yoke may require a new axle, then the question would be the transmission. Considering the cost will be around 3000.00 I would like to make a sound decision. I tow a rv which is just under 6000 lbs. Just not ready yet to invest in new truck.

    Well regardless of rear axle, that is overloading THIS truck!

    Perhaps. It is quite bothersome when determining exactly what it can tow. No one really has the correct answer. According to some a 1500 4x4 crew 5.7 liter with 355 rear can pull up to 7500 lbs. I had my rear end problems long before I towed anything. The truck is not stock. Over load shocks and helper leaf have been installed. Truck has a class 4 hitch. Even dodge at the time said it could pull 8000 lbs.

    Without actually looking at it i guess i should not say but towing capacities are vastly overrated!
