Wheel Wobble

[Ardee83]

Last summer one of my buddies noticed that the passenger rear tire was wobbling. I had him drive the truck I followed behind. Man does it wobble it's worse at slow speeds and when I hit 65+ mph I get some vibration.

I had an idea yesterday to swap the rear tires to see if it was possibly a bent rim, but the same issue remained on the passenger rear tire. I have read a few other threads regarding people with similar issues but there are very few.

My very first thought is bent axle. But instead of just diving into oh better go buy a new rear axle; I would like to eliminate some of the other issues it may be. That is where I need everyone's help I don't know what could be causing this issue. Please chime in and let me know your thoughts. 1983 2wd SWB c10 Thanks Ryan
