help with a front-end squeak

No I dought it is the balljoints,they (balljoints) can be moved up and down a little bit when they are no longer good or worn past their use. I would bet my bottom dollar that it is the inner tie rods,the ones in the steering rack. Is the car lowered? and do you have heavy rims? I went through this for a while then I just replaced the rack my self and got an alignment after.This is better than paying someone to fix the inner tie rods and you would still need an alignment. The steering racks at stangparts.com are pretty cheap. Try this: with the car turned on and being on a flat surface, leave it in neutral and keep moving the steering wheel left to right with youre hands at 10 and 2 if the "squeek" occurs it is probably the inner tie rods also have a freind or family member stand out side the car and just roll down the passanger side window both of you listen for the noise Jones out........

Could be one of the worn out rubber bushings in the front end somewhere, most likely a control arm.

If you think it's the A arm, spray some silicone on it and try agian.......

Balljoints are cheap I have 3 pairs of stock ones p.m me and I'll give them to you......jj

You can get Steeda X-2s for $99.

I just got done installing mine.
