Front driver side hung up?

We are nearing the end of the restoration and have a problem that we narrowed down to what looks like the front driver suspension.
The rear passenger side was higher than the other so we placed in on stands and measured to see if the unibody was tweaked?
During the restoration we found that the driver door and front fender had been replaced and some damage to that pillar from years ago.
Here is my question.
When it's in the air you can see that wheel is held up about 1-1.5 inches. The floor isn't perfectly level but it's pretty close.
What do you guys think? Bad could spring, its original. Bad upper a arm? Could be tweaked from the accident?
Looking at just replacing the with tube a arms and new coils, think that'll resolve the issue?

Re: Front driver side hung up?

Upper A arm binding? Did you tighten the shaft end bolts with the wheels in the air? The weight of the wheels should pull down on the upper A arms to the same extent. If you back off on the bushing bolts the uppers will rest on the stops and the wheels will hang down the same. Tighten them all to the same torque with the full weight of the car on the ground after bouncing it a few times so there's no binding in the bushings. I think the specs are 50 ft-lbs.

Re: Front driver side hung up?

You don't have the jack centered and the wieght of the car may be throwing it off that much.

Also check the sub frame mounts. The sub frame some times rust out on top around the body mounts.

Re: Front driver side hung up?

Take a close look at the body mount locations on the sub frame for distortion, particularly the front ears. Check the body mount bushings while you're down there. Check the wheel spacing on the front wheels relative to the inner and outer fender to make sure they are even.

Nice car.

Thanks Roger,
The jack is on the center beam and we moved it from the center to where it was, didnt matter, the wheel was still the same distance from the ground. Its hanging up.
Car is just restored, no rust on the sub frame mounting area.

Thanks, great advice. I will give that a shot this afternoon to see if it'll drop it down, its worth a shot.
If that doesnt work I assume there is a bend in the upper A arm or the coil spring is shot, I think the spring is original equipment.

Re: Front driver side hung up?

Pull the shock out. Might be too short or damaged. Loosen the upper A arm bolts. Check the lower arm for any binding at the bushings. May be bent.

Most first gen camaros have limited room for the shock absorber up in the spring pocket. It's where the shock body goes up past the upper coil spring seat. If the shocks are large diameter, they can jam up in there and get stuck. I saw it happen to a Trans-Am vintage race 69 Camaro. The guy put large body Koni's on it and they got wedged in there. The shocks limit droop travel, so compare the shocks for full extended length.

Disconnect one sway bar end link and see if the bar is twisted.
All A arm inner pivot bolts should be tightened with the car on it's wheels, or the bushings will be pre-loaded and affect ride height.

Re: Front driver side hung up?

Have you checked the bump stops on the upper control arm? They tend to deteriorate over time. The one on the passenger side could be shot or missing. Just a thought.

Re: Front driver side hung up?

Thanks for all the replies guys.
We wet back and looked through everything again and included everyones suggestions. Looks like its a combination of the original coil springs possibly and a bent upper a arm.
I went through a search of tubular a arms and seem to have settled on Global West.
I will post a few follow ups as I go along.
Thnaks again

Re: Front driver side hung up?

I am towards the end of the restoration and have always had a "lean" on this car that I have been chasing for years.
All of the front end was restored in 2012 so I always thought it would be corrected with this winters rear suspension update, 5 leaf with new perches.
Poking around I was about to pull the trigger on a Global West complete front package, Delalum upper and lower arms and GW S2 springs that would lower it 1 inch. The 1 inch concerned me cause I wanted to keep the original look.

Anyways, I found a thread about lean, looks like a lot of other guys had the same problem and solved with coil spring spacers. For $20 its worth a shot for the time being.....
