Yeah...basically. Sometimes its real hard...sometimes its just a gradual. Somtimes itll jerk over real fast too.

overall, it just feels like a bad alignment. but firestone gave me the printout, and it all looks like it was aligned well.

 

I would get your brakes checked, and maybe even replaced. You say the rotors are warped, and sounds like to me maybe the front passenger side piston maybe stuck/sticking. Just a thought.

 

does the car ride smooth, it could be a off balence tire pulling the car one way or the other.

 

Well, i just got the tires balanced, or so they say, at wal mart.

i think the rotors are warped because when i brake, the steering wheel shakes bad through certain speeds.

 

shaking steering wheel while braking IS a warped rotor. Since you're not the original owner, do a carfax on it and find out if it's been in any accidents. Front end collision just right would tweak the steering enough to where it would be 'fixed' to the naked eye and to spec but 'dog tracking'

Have someone drive your car or you drive your car and have a friend that is somewhat knowledgable about cars drive in another car. What you should look for is the following. From the front (as you drive behind them) BOTH front wheels should look like they're pointing in the same direction and be in the same line front to back (in other words your left front tire should be in-line with your left rear tire and same goes for the right). The body of the car should also be parallel to your wheels.

Ever see an old pickup truck where the back end seemed to be slightly pointed to the right or left as it was driving straight? That's dog tracking.

Also for alignment purposes some people use Caster/Camber plates when lowering the car. The reason is the center of the steering axis's are changed when you lower the car. Some cars need it, some don't. Mustangs already have crummy Caster settings causing the car to track ruts and imperfections in the road at stock height. Lowering a car can magnify this.

Well the CarFax stated the car was checked for framed damage, however the "frame damage indicator" was normal. The car aligned fine and the Ford tech said he saw no evidence "impact damage." The carfax DOES NOT say that it was wrecked, or an police report was filed or anything like that. Just that the frame was checked

The car does track imperfections in the road like hell. It's almost scary sometimes.

I am really at a loss now. I'm going to take it to a different dealer and explain the whole situation.

Ford did say that it could be internal parts of the tires being messed up. I guess if they didn't rotate the tires, this is possible.

According to Stangpower, if there is a difference of half a degree or more, the car will pull to the low side....

WELL...as per the alignment paper, the right side has 3.4 and the left side has 3.9 caster. So, if he is right, then the caster difference might be causing the car to pull....

Does this seem on target or is it not that big of a deal to make difference in steering?

 

if it pulls to the right and your wheel shakes with braking then my guess is that a tire is out of balance or you lost one of the weights off your wheel

check it

 

WALMART?????This is probably why the rotors are warped.Those people don't know what a torque wrench looks like let alone how to use one!!!The pulling to one side could be a bad bushing in the control arms.I had this problem in a Lincoln MK VIII, when braking the car would pull to the left so I replaced brake pads,rotors,brake lines,even fluid.Tires were rotated and alignments were done and no one could find anything wrong.I finally gave up and took the car to the dealer.They called the next day and told me that the problem was the lower control arm bushings.Parts and labor cost almost $1000.This cost was for a Lincoln which no aftermarket parts exist for so your cost would be much less.So if the bushings are worn enough they could cause this trouble and still not show up in an alignment.

 

Well again, all of the problems I am saying existed when BEFORE the wal-mart experience. I simply took it there to see if a cheap balance might help.

So, my plan of action today is to take it back to the alignment shop, show them the .5 degree difference in caster, and ask them to correct it. Hopefully this is going to correct the issue.

BTW, thanks for all the responses
