1979 Sierra Classic question

[79ClassicSierra]

Hey y'all, I have a 79 Sierra Classic and every so often the truck will start rocking while driving, like if you had a bent wheel on your bicycle and you get the wobble, that's what my truck does every so often. Does anybody know what the problem could be, I just can't figurE it out and remember it doesn't do it all the time.

Check the condition of your tires, one of your tires could have a broken belt. Try rotating your wheels and see if the wobble moves to the other side or goes away.

Start with that and keep us posted.

My tires are brand new, somebody said that it could be my joints or suspension, I don't think that could make the truck wobble, do you think it could be a bearing issue?

it could be a bearing issue. but then, it could also be a suspension issue. or both. I am betting it is a bearing issue as the truck is an older model, and probably never had any work done to the wheel bearings. Shocks could be a culprit too.

My guess is that it is an issue with your suspension like a broken or cracked leaf
