Detailed Description

This Dorman drive shaft assembly is built for rear driveline replacement on the Lexus LS400 and is engineered around the listed fitment for 1990-1994 vehicles. The assembly uses steel construction, bolt-on ends, and a pre-greased design, with universal joints included and no slip yoke, grease fitting, CV joints, or axle nut included. With a 0.083 in wall thickness and 1 in maximum slip, it provides the dimensional setup needed for a direct driveline service on the Lexus LS400 rear application. The Dorman 986-953 is a practical choice when replacing a worn or damaged rear driveshaft and when a complete assembly is preferred over rebuilding individual components.

This part cross-references Monroe Shocks & Struts (e.g., 3710050021) for the same application.

Common Problems This Part Can Address

• Vibration from a worn or out-of-balance rear driveshaft
• Clunking or driveline noise from failed joints
• Excess play caused by worn yokes or shaft components
• Damage to the original shaft tube or driveline assembly
• Service needs on a 1990-1994 Lexus LS400 rear driveline

Installation Notes and Tips

Verify flange-to-flange and yoke-to-flange measurements before installation to confirm the 56.5 in collapsed length and 57.5 in overall drive shaft length match the vehicle. Inspect mounting surfaces, driveline alignment, and companion components before bolting the assembly in place. Because this is a rear application for the Lexus LS400, confirm the vehicle’s rear driveline configuration and compare the original shaft dimensions to the replacement part number 986-953.

Quality Assurance

Dorman supplies this assembly as a standard replacement driveline component with new major wear parts already installed and pre-balanced for service readiness. The design focuses on restoring driveline operation with a complete assembly rather than rebuilding the original shaft.
