TIMKEN 344A/332 bearing

40x80x21

The Timken bearing was actually a Koyo, which is what Toyota originally installed. The process took a couple hours per side using a screw type FWD bearing press kit. After over 1000 miles on the new parts, the car remains silent, smooth and feels new again. This was my fourth time using Timken bearings with zero issues.
