I am trying to find lower control arms for my girls g37x coupe and having a hard time finding the right part. I have looked on the infiniti parts website to find the front lower control arm for this car and it list 3 right and 3 left lower control arm part numbers. However the diagram that they show has part numbers 545001 and 545000. I called my local nissan dealer an they told me that they are the same on the coupe rather it be a rear wheel drive or all wheel drive he shows the same part numbers. When talking to him he said that it was the same for both. My question is, is there a difference in the all wheel and the rear wheel drive. I am really hoping you guys have some experience with this. She just bought the car a month ago and we noticed popping in her front end and I found the drivers side ball joint is bad. We are replacing the front upper with z1 and front lower on both sides plus all tie rods at the same time.

Car is 2009 g37x coupe 7sp. auto trans with 114k miles on the odo.

Thanks

Provide VIN and I will look it up in the fast system.

Hi there,
Did you ever figure that out? Are the parts similar enough to be able to order the LCA from the RWD car and use in the AWD?
Thanks

They use different part numbers. Just buy the ones for the AWD car.
