Took my car (2005, 37k miles) to my tire dealer (Les Schwab) for their complimentary rotation and to have the alignment checked due to a noticeable pull to the right. They said:<p>1. The "cross caster" was at the limit of its range (-0.3) and the "total toe" was off (-0.28 compared to a stated range of 0.00 to 0.20). However, they said there was no point in adjusting the toe if they couldn't adjust the cross caster, and they did not have the equipment to adjust the cross caster; only the dealer did. No one seemed able to explain coherently exactly what "cross caster" means. What is it, and does it sound right that this is a "dealer fix?"<p>2. They said my rear differntial is leaking gear oil. I crawled around underneath the car today, and do see some (not much) wet, along with a few spots on the garage floor. I assume this<I> is </I>a "dealer issue," especially since I have an extended warranty. What am I looking at in terms of a repair?<p>Thanks.
