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?
