Can you list all of the alignment print-out? Right side and left side may differ, and with caster as low as +1.5° your car may be more sensitive to right/left differences.

Just what size are the tires?

and yes balding is seen on the insides of the tires as they were driven on for a while when the alignment was out of whack.
Are all four tires worn like that? If the rear tires are not, swap the tires front to back and see if it gets any better. A front tire that has trouble deciding whether it's rolling on the flat part of the tread or on the sloping worn part is a tire that won't want to track straight as you go down the road (due to pavement unevenness).

I know that all my suspension components are stock (replaced with newer parts) but they are pretty much direct replacements
Was the chassis/frame checked for straightness as part of the repair?

Wish I had the alignment print out but have not been down to the alignment shop and I am not sure if they can produce one

Only the driver side front tire and maybe the passenger side front show balding on their insides. the drivers side being much more.

yes they thought something was wrong with the frame because my body panels are not in correct placement but they determined the body panels need alignment and that the frame was fine itself. They just checked again if the reason my car was pulling one direction was the frame but nope.

This is where I got thinking. The last time i took my car they put a new idler arm (the car now tracks straight at high speeds) and they took my rear tires and put them in the front and vica versa.

I just barley drove the car today and the freeway and it is everywhere! It is very scary if 1 tire hits a little bump the car wiggles and it feels as if I am going to lose control and go in the other lane.

Before they switched my tires up the only problem I had was it pulling to the left and this jumping all over when hitting bumps only occurred when 1 side of the car hit a big bump such as driving over a sewer in the side of the street. Now every little blip in the road causes the car to swerve which concerns me.

I am thinking it has to be the tires right? My front tires (which were my rear before alignment) are 4+ years old and they dont even make them anymore.

Here are my current front tires the ones that are 4 years old
Kumho Ecsta 711 Size: 215/45/R17


Here are my current rear tires:
Kumho Ecsta AST Size: 215/45/R17


could it the thread difference be the cause of my problem or something with the 4 year old tires which are now in the front of the car which is causing it to jump all over worse than ever before??? The wearing on these front tires is even btw.


Any opinions would be greatly appreciated.

Damn, if I were you I would check to make sure they got the lugnuts tight. They probably did but with it doing that right after they had the tires off I would still check just to be on the safe side.

If your upper or lower ball joints are bad they will change your your alignment when you go over a bump. Did you a check them?
Jack up the car and have a buddy push and pull both the top and the bottom of each tire as you carefully watch for any horizontal movement on the upper and lower ball joints .
Maybe when you hit the curb and broke the the UCA it damaged the LCA ball joint.

That is not really the proper way to check ball joints. You have to unload the spring and then check the up and down or verticle motion on the ball joints.

I said unload the spring and that is not quite right. What you have to do is unload the the ball joint by loading the spring. The best way is to use a 2x4 between the frame and the upper control arm before you jack it up. that will unload the ball joint.

they replaced a lot of the suspension parts little by little because when they replaced 1 thing it was found that also another thing needed to be replaced and they have checked over the suspension

could the steering gear box cause this?

or the tires like i thought?

Is the steering wheel sloppy? With the car sitting, how much slack is there in the wheel. If its only a little then the steering box should be fine.

EDIT: The wheel itself seems tight sitting in the garage before it gets difficult to turn. Did not keep turning until the wheel turned though.

But while driving I can pretty much pretend like im a lego and move the wheel back and forth quite some bit before the car actually goes anywhere. Probably like 10 oclock - 2 oclock before any wheel movement begins


also my steering wheel doesnt sit straight it tilts the right a little. How do I fix this?


If its not my box what is causing me to wander into all the lanes?




p.s. the shop had said they had put a set of different wheels and tires on the car and the wandering problem was not their anymore. And it drove perfect. Not sure what sizes exactly.

^if that helps

That's way, WAY too much free play. Something is either loose or possibly bending. Check everything that moves for looseness relative to the things it is connected to, and inspect the "frame" around where the steering box attaches.

The steering wheel is "off" either because the toe adjustment was not done in a manner that kept it centered or because something moved afterward. Or a little of both.

I would suspect wrong-offset wheels causing a problem before tire size, particularly since 215/45-17 is within about 0.3 inch of the height of the 185/75-14 that's considered a direct OE replacement and within 1/8" of the height of the 195/70-14 that is also used without any problems. What width and offset are the 17" wheels, and what make/model/year car are they originally listed to be installed on? Honestly, I doubt that this is the problem behind having 1/3 of a turn of free play at the steering wheel.
