Toyota 4Runner Transmission Bearings

The function of a bearing is to support a rotating component while preventing its undesirable motion and reducing friction between the surfaces. With the duties of these components and demands put on them varying substantially, their design patterns differ as well. For example, while engine bearings that mount the crankshaft in your Toyota 4Runner are simple multilayer plates, what holds the transmission input and output shafts are far more sophisticated bits with a set of balls or rollers inside. These are respectively known as ball bearings or roller bearings. While featuring excellent friction mitigating qualities, such a design is vulnerable to vibrations and shocks that gradually deteriorate the rolling elements and let the shaft play.

And even though Toyota’s 4Runners are globally renowned for their ruggedness and high build quality, they also suffer from bearings wear. And since there is no technique for restoring a broken bearing, the only option allowing you to fix the issue is replacement. In this case, the stronger the repair part, the longer it will serve. That’s why we exclusively carry high-quality Toyota 4Runner transmission bearings from Timken, SKF, and other similarly reputable manufacturers.
