When shifting transmission into drive there is a loud grinding noise and back tire wobbles

Can you get a recording of this? I am not sure what you mean by the back tire wobbles when this happens.

If the noise is coming from the rear end, we need to make sure the drive shaft is spinning. If it is and you are not getting movement plus there is a grinding then we need to remove the rear cover and look for metal.

Let's remove the cover which can be done on the ground and drain the fluid and make sure there is no metal. Let me know what you fin and we can go from there. Thanks

Good morning,

This sounds like a broken axle in the differential itself.

You need to remove the cover and remove the axles and inspect for damage.

I attached the procedure for you along with a picture.

Rear Axle Shaft Replacement (9.75 Inch Axle)

Removal Procedure
1. Release the park brake.
2. Raise the vehicle. Refer to Vehicle Lifting.
3. Remove the tire and wheel assembly.
4. Remove the rear steering gear assembly.
5. Remove the steering knuckle assembly.

6. Remove the lock clip from the axle shaft end. The lock clip is spring loaded and fits securely in the axle shaft slot and may need to be push off the shaft end with a screw driver or related tool. Pushing the axle shaft inwards towards the gears my help in removal of the lock clip.

7. Remove the axle shaft.

Important: When removing the axle shaft do not rotate the shaft. Rotating the shaft will cause the gears to move. Misalignment of the gears will make the assembly difficult.

Okay, as it states it is for the rear axle.

What size rear do you have? Are they solid axles?

Roy

Okay, that is a 2500, not a 1500 that you listed.

These axles are more common for failing.

Can I have the complete VIN number?

Roy

I need the complete VIN number from the drivers door or from the tag on the dash.

Roy

There are several options for the differential.

This is another one:

8. On axles with a locking differential, use a screwdriver, or a similar tool, in order to enter the differential case and rotate the lock (1) until the lock aligns with the thrust block (2).

9. Push the flange of the axle shaft (1) toward the differential.
10. Remove the C-lock (4) from the button end of the axle shaft (1).
11. Remove the axle shaft (1) from the housing (5).
