Detailed Description

This Dorman OE FIX axle shaft assembly is built for Toyota Tacoma rear left applications where the original axle and bearing service would normally require pressing components apart and reassembling them separately. By supplying the critical components preassembled, 926-139 simplifies the repair process and reduces the chance of damage during installation. It is a direct-fit solution for 2005-2023 Toyota Tacoma rear left service, and the loaded design supports a cleaner replacement workflow on trucks with a semifloating rear axle.

The assembly features a 33 mm shaft diameter, carbon steel construction, a rust-resistant coating, and included brake dust shield and backing plate. The hub bearing, axle shaft seal, and ABS tone ring are already part of the assembly, helping restore proper wheel support and sensor signal function. If you are searching for a Toyota Tacoma rear left axle shaft assembly, Dorman 926-139 is the relevant OE-style replacement.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
