Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is on a level surface and secure it with jack stands.
Disconnect the battery to prevent any electrical issues.

2. Drain Differential Fluid

Sub-steps:
1. Locate the differential drain plug and remove it using a socket set.
2. Allow the fluid to completely drain into a suitable container.
3. Inspect the fluid for metal shavings or debris, which indicates internal wear.

3. Inspect Differential Components

Sub-steps:
1. Remove the differential cover by unscrewing the bolts with a socket set.
2. Inspect the ring and pinion gears for wear patterns or damage.
3. Check the bearings for signs of wear or pitting by rotating them by hand.

4. Replace Worn Components

Sub-steps:
1. If any gears or bearings are damaged, remove them carefully using a bearing puller.
2. Replace with new OEM parts specified for the Ram 1500 DT.
3. Reassemble the differential with the new components, ensuring correct torque on all bolts.

5. Refill Differential

Sub-steps:
1. Clean the differential cover and apply a new gasket or sealant.
2. Reinstall the cover and tighten the bolts to the manufacturer's specified torque.
3. Refill the differential with the recommended fluid type and amount.
