The front end seems to be unsure meaning wanting to deviate from a strait line to either the right or the left, many times switching between the two. This is most prominent on the highway. An alignment was just done a few weeks ago. (Day after I did upper control arms due to ripped boots and loose front end.) Lower control arms were done by a shop about 2 months ago. I am at a loss now as where to look. Thanks in advance for your help.
