why is my Ram 1500 DT (2019-Present) rear end making noise when going around corners

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a level surface with the parking brake engaged.
• Use jack stands for safety if raising the vehicle.

2. Differential Fluid Inspection

• Remove the differential cover using a socket set.
• Allow any fluid to drain into a suitable container.
• Inspect the fluid for metal shavings or debris.
• If the fluid is dirty or low, replace it as follows:
  • Clean the differential cover and mating surface.
  • Reinstall the cover with a new gasket or sealant, torqueing bolts to manufacturer specifications.
  • Fill the differential with manufacturer-recommended fluid using a pump until it reaches the fill hole.

3. Suspension Component Check

• Inspect all rear suspension components (control arms, bushings, shocks) for wear or damage.
• Replace any worn or damaged components using a socket set and torque to specifications.
• Ensure all bolts are tightened to the correct torque settings.

4. Wheel Bearing Inspection

• Remove the rear wheels using a lug wrench.
• Inspect the wheel bearings for play by wiggling the wheel.
• If play is detected, replace the wheel bearings:
  • Remove the brake caliper and rotor.
  • Remove the axle nut and hub assembly.
  • Replace the bearing with a new one, using a press if necessary.
  • Reassemble all components in reverse order, ensuring proper torque settings.

5. Axle Shaft Inspection

• If issues persist, inspect the axle shafts:
  • Remove the axle shafts from the differential.
  • Check for any bending or damage.
  • Replace with new shafts if necessary, ensuring proper installation and torque settings.
