My alignment has been very off on my car so I tried to take it to alignment twice, and they told me they could perform it, but it was not going to be any good. so I took it to an auto collision shop and told me and then was told it might need a pull from under the car. the mechanic said all the measurements were good and everything seem to be fine, the only thing was that the spindle was shorter out from one side about one fourth of an inch. i wanted to know exactly, of what the spindle consist of .since i might be buying it online or junk yard. would really prefer a new one but the cheapest is 320.00.
