72 GMC Suburban front control arm?

Noticed a lot of vibration in the front end. Discovered what seems to me to be a significant wobble or excessive play in the upper control arms.

Can I simply tighten these up or do I need to upgrade/replace bushing? Possible alignment?

Re: 72 GMC Suburban front control arm?

probably wouldn't hurt to put new bushings in, especially if they are original. an alignment after that is almost required IMO.

Re: 72 GMC Suburban front control arm?

Where specifically do you feel is it loose? At the shaft to mounting bolts or @ the shaft to bushings?

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.

It looked to be at the shaft to the mounting bolts.

If it looks loose there, that suggests some shims fell out. Try to tighten things up & get it aligned.
