Detailed Description

This Dorman rear drive shaft, part number 936-258, is built for 1986-1991 Mazda RX-7 models with a rear driveline application. It is a steel replacement shaft with a 3-inch diameter, 38.125-inch length, and 0.065-inch wall thickness, making it a direct-fit service part for the specified vehicle range. The OE FIX design focuses on serviceability by replacing the original permanently staked U-joint arrangement with a setup that simplifies future maintenance. This part cross-references Monroe Shocks & Struts (e.g., P03925100A) for the same application.

What This Drive Shaft Helps Address

• Worn or damaged rear drive shaft assemblies
• Service difficulty caused by non-serviceable factory U-joints
• Driveline vibration related to shaft wear or imbalance
• Noise from deteriorated driveline components
• Maintenance delays when the original shaft cannot be serviced easily

Installation Notes and Tips

Verify fitment by year, make, model, and rear position before installation. Confirm driveline measurements and inspect related components such as U-joints, mounts, and companion hardware for wear before reassembly. Because this shaft is not adjustable, correct application matching is important for proper installation on the Mazda RX-7.
