I have 16"x 7" stock steel rims on the truck. The tires on them have some wear on them but not so much that it would be an issue. I did have 18"x10.5' American Racing rims on before and they felt like big balloons. So going back to stock rims did help but the wobble came back. I will jack the truck up this weekend and see if i get some play on the tires. If i do get some play would changing or even regreasing the bearings help?

 

Not unless the nut is lose or the bearings are crap. Like I said I had it for years on 1/2- 1 ton axles and swaping out the tires are what fixed it that's almost always the case. My first k5 needed every ball joint and tie rod when I got it and didn't wobble at all

 

i got a 88 S10 blazer and when i hit a bump real hard it pulls to the side the bump is on i know i gotta replace the idle arm and pitman arm u may want to try that
