70 Mustang Front-End problem

Hello everyone,

I have been slowly replacing the front end components on my 70 Mach 1 (and kind of now wish I had left it stock).

I am running globalwest front springs and bilsteins that are supposedly valved for classic mustangs. I am also running opentracker's roller perches, globalwest upper control arms, new stock lower control arms, and a globalwest swaybar.

I have not touched the strut rods (other than adjusting them for alignment) or the strut rod bushings. The bushings LOOK ok to me.

I also re-used my factory rubber spring isolators on top of the coils because they looked fine (had 68k miles on them).

When I drive down the road the front left bangs and clatters like a horse cart. I am trying to figure out the source of this. If I put the car up on the lift and try to shake the wheel as hard as I can it does not deflect significantly. Also if I drive down a road where the road banks down toward the passenger side (crown is raised), and the left side is under more load, then it rattles constantly.

I can not see or find any loose parts underneath. The only other issues I can see is that when I adjusted the eccentric on each side the inner wall that the eccentric rubs on bowed outward (I had the wheels supported when I did this).

The car sits about 1/2" lower on the front left on level ground.

I have not had the car professionally aligned yet, but I do have one of the handheld tools that bolts on the wheel and a lift, I have put off getting it aligned because of the noise - if a part is bad I know I will be out my money when I have to have it aligned again. The car drives straight and the alignment checks ok with the handheld tool on the ground.

Anyone have any ideas? I have considered replacing the spring isolators, but the globalwest isolators say they raise the car, and it is already pretty high in the front. I have also considered going to eccentric eliminators, maybe the front left eccentric is moving under load? Do alignment shops usually work with these?

Horse sence,

Thanks for the reply. I checked that and both bolts at the bottom are snug. I can not wiggle the shock with the wheel supported in the air.

I did notice yesterday that the wheel shake and rattle largely goes away when I am on the brakes so I am thinking maybe wheel bearing, going to try that next.

Hack I have the stock 1970 front discs. If I am going down a relatively smooth road where it is banked down to the right and the left is under load it rattles constantly, and its pretty loud and sounds/feels like the wheel is moving around.

Sometimes working on these things makes me feel dumb lol. I had a friend shake the wheel hard in the air while I looked with a flash light and it looks like both my idler and pitman arm have quite a bit of play.
