How many drive belts are there to replace on 06 GX 470 and what mileage do you suggest these be replaced? having some minor belt noises and I have 70000 miles on mine. thanks.

 

One, i did mine at 115,000, old one still looked good. took a few minutes to get that belt wraped around all the pulleys, scraped wrist and elbow..but still pretty easy. Not enough blood to justify paying lexus, LOL
