I just purchased an 04 xterra, it was pulling to the right so I had the dealer do the alignment, there is about an inch more space now between the tire and wheel well on the drivers side on both wheels, I am new to all of this, can anyone tell me what would cause this and how to fix it?

i dont know but I had mine aligned cuz it was also pulling right

An inch more space as in the front end appeared to have been lifted an inch? It's possible that the alignment problem was due to T-bar sag and they cranked your t-bars up.

What is the height from the ground to the center of arch of your wheel wells both front and back? I believe stock measurements were like 35" in the front and 36" in the rear. Or maybe that's with a PML... either way... can you get those measurements for us?

Is the alignment problem fixed and you're just wondering about the gap or is your alignment still pulling?
