Hemi-royd those words above sound pretty wise to me.mitchgmace said:I also wasn't saying for sure the axle is bent. But sounds just like my son's. Like slammed1 says. After jacking truck up and rotating it. You can see if it is bent. It was the right rear on ours. I have heard many stories of the letting loose. Catch it before it breaks and does real damage. It's an easy fix. I got a new axle, bearing, seal and replaced it all myself for under $200.00.
A lot of damage if it breaks while driving. Good luck and be careful.
Along with Slammeds pictures I would make this a priority.
Will get real expensive and real dangerous quickly if you don't.
