Hello, when my truck is lifted off the ground, there is about 1/4 inch play when I push and pull on the rear tires. I was told that the C clips inside the differential that hold the axle shafts in place may be worn and need to be replaced. Practically every time I go over a bump, there is a pretty loud noise from the rear. Am I on the right track? Should I also change out the bearings and seal while I am at it?

Good evening.

No, the play is good. There should be play in the differential. 1/4 inch is not bad.

As far as the noise, you will need to look at the shocks and rear suspension components for wear.

Thank you! When my car goes over any bump or uneven road, I can actually feel movement in the rear as well as hear the noise. Does that sound more like the springs to you?

I replaced the rear shocks with ones that dealer recommended 2 years ago but those shocks squeak from day one.

You have something that is securing the rear moving. You need to look at the arms and bushing in the rear.

I don't have control arms in the rear. I replaced all the control arms and bushings in the front.

Do you have leaf springs or coil springs?

You have the arms in the rear. They are just called trailing arms.
