I have some roadwalk on my 65 mustang. I put on new tires but that did not help. The front end parts all look good, but I see some slack in the power control valve stud. Could this be the problem and if so is it common?

 

Before you can say if the front suspension looks good or not you need to jack up the front of the car and look for slop in the components.

 

More caster promotes straight tracking at the expense or steering effort.

I like a lot of caster for highway cruising and for resistance to tram lining.

I've been disappointed too many times following "professional" alignments.

I do my own alignments now. The key is $30 digital angle finder.

My 64.5 does not have adjustable strut rods thus requires shims (144 pcs = $8.00) to adjust caster. I've had shops "adjust" alignment w/o shims; can you spell rip off.

 

The control valve could be your problem and yes it is pretty common...However the stud does tighten up some when the engine is running and the pump is supplying hydraulic pressure...

 

lol. you cant really diagnose someone's alignment problem over the internet. the guy above is correct, you need to jack it up and check for loose components. A very common problem with earlier mustangs is that the bushings in lower control arms take a complete ****, which means your car can never be aligned without a new one. that so called "stud" or bolt in your ram, actually jus adjusts pressure, it more less will only take out play in the steering wheel. There could be TONS of problems that could promote a bad alignment.

 

Why not?

I realize you can't align a car over the internet. I am just looking for things to point me in the general direction.
