Looking at 2001 4Runner-Things to look for?

I am looking at a 2001 4WD 4Runner. What if any, unusual things should I
check for? I am very familiar with cars, but not up on any chronic
problems with these. Thanks, Bob

Great trucks, but that vintage does have one thing you should look for -
leaking rear axle seals. It's fairly common on the late 90's and early 00
models. The best way to check is to remove the rear drums, make sure that
the shoes and backing plate are bone-dry. Replacement can be VERY
expensive, involving new shoes, drums, and bearings.
