Suspension issue
#1
On my 71 Mach 1, I have been having some suspension noise lately.  My Driveway is slightly up hill.  When I back out of my driveway and turn the wheel so the rear end goes to the right, as my front left tire comes off the driveway onto the street I get a big Noise of some kind.

Should I be looking at the upper or lower control arms?  Or the steering linkage?  I notice this doesnt occur when turning the other direction out of the driveway.

Thanks in advance for your help!

Maybe I can post a video tomorrow.

I used to get a clunking noise going downhill into a sharp right turn while braking.
It disappeared after I changed upper and lower control arm bearings.
Stupid question first: are the moving parts in your suspension greased well?

Edit: I just thought about something else. Check the rubber insulator at the top of the coil spring. I don't know how steep your incline is but could the coil be shifting a little?
I'm no expert on these things but that's another source of noise I've had on mine.

jowens1126,

Could be the strut rod bushings. They will make all kinds of noise if worn out.

I meant the lower and upper ball joints. I had a temporary blackout this morning looking fir the correct terms. Problems of a non native speaker. Smile

Does this happen when you turn the tires all the way until the stop? Sometimes when hitting the stop it makes a clunky noise.

jowens1126,

It could be the upper control arm bushings. They sometimes work them selves out causing slop. Luxstang is on the right path!

You don't have to turn it to lock, it makes the sound anytime the wheel is turned enough to turn in that direction only when you hit a bump of any size.

My vote is for upper control arm bushings & shafts. If you're there, you should replace the ball joints and spring perches.

FWIW, if you are not sure if the front suspension has ever been rebuilt, just do the whole thing. The parts are cheap, the only real specialized tool is a spring compressor and a 1" deep well socket for the strut rod nuts. Use quality name brand parts, not the "nice price" kit some of the Mustang vendors sell.
