NISSAN QUEST WHEEL PROBLEM

2006 Nissan Quest • 150,000 miles

My quest pulls to the right and shakes when I break, I had new
struts and routers put on 5 months ago and now I was told I need to replace the r/f lower control arm. Is it worth replacing?

Do you want to solve the problem? While the control arm bushings are common failure items on some vehicles, it is more likely one of your new rotors is warped. That can happen on any new rotor but is much more common with Chinese rotors. We age our cast iron parts for 90 days before they get their final machining. Chinese rotors age on your car and often warp. Usually they are fine after one touch-up machining. Your rotors should be checked for thickness variation first, then "lateral runout". Thickness variation will cause the brake pedal to pulsate up and down once per wheel revolution. Lateral runout shakes the steering wheel when it's bad enough. Lateral runout is a common result of not using a torque wrench when tightening the lug nuts. The warpage is caused by uneven clamping forces on the wheel along with repeated heating and cooling cycles.
