Here's something I found out yesterday as well - Tony, please help me out with the terms here.

When they took the wheels off and took the CV's etc out, where the wheel bearings sit on the CV stem (spindles???) are starting to look worn - they told me that a lot of the time people get what they believe to be a bearing wobble and change them out, only to find the wobble is still there - essentially it's because the spindle? is wearing down and the bearing is loose on it. Mine weren't too bad, but they also said it is more common on nissans than toyotas (yuck) as the bearings are closer together? and hence the wheel load on the bearings is worn over a shorter distance and hence they wear quicker?

Tony - are you with me? If so, can you explain it properly please .... I'm still just an apprentice!!! lol
