Welcome John! Heres a link to just about everything you need to know when buying a 4Runner. 3rd Gen 4Runner Buyer's Guide When you test drive it, check for things like shaking at freeway speeds as well as monitoring the temp gauge. Like Dan.3 said, watch for radiator issues. The pink milkshake is only a big concern if its an older 3rd gen or has quite a bit of miles. The shaking could be as easy as new steering rack bushings and is a common thing for a lot of runners to have. check the tires also. if the insides of the tires are wearing faster than the rest of the tire, that points to bad lower ball joints. this is a very common issue with the 4R, and if it is a 01-02 model, there is a toyota sponsored recall on the LBJs. I would take it to a mechanic you trust, not toyota. they know if you buy the car, youll probably be seeing them again to order parts, service, etc. but you made the right choice coming here before buying! if i knew what i know now (thanks to this site) when i was buying my 4R, things wouldve gone differently, and i wouldnt be stuck trying to fix someones old bumper car! Good luck with your purchase and welcome to the forum!
