Detailed Description

Dorman 986-084 is a rear drive shaft assembly engineered for 2007-2012 Acura RDX models. It is built with steel construction, a 0.065 in wall thickness, and flange ends on both sides for a straightforward replacement in rear driveline service. The assembly is supplied pre-balanced and uses new yokes, tubes, CV joints, and universal joints to restore driveline function without rebuilding the original shaft. This part cross-references Honda/Acura OE number 40100STKA02 for the same application.

What It Helps Fix

• Driveline vibration from a worn or out-of-balance rear shaft
• Clunking or driveline noise from worn joints
• Excessive play caused by damaged yokes or tubes
• Service issues on a rear drive shaft with flange connections
• Replacement needs for a 2007-2012 Acura RDX rear driveshaft

Installation Notes and Tips

Verify flange-to-flange measurements, compressed length, and rear-position fitment before installation. Confirm the vehicle is a 2007-2012 Acura RDX and compare the original shaft dimensions and mounting style to Dorman 986-084. Because the assembly is not adjustable and does not use a slip yoke, proper alignment and correct flange engagement are important during installation.

Quality Assurance

Dorman supplies this as a complete replacement driveline assembly with new internal components and pre-balanced construction for consistent fit and function. Dorman 986-084 is intended to replace the original rear drive shaft on confirmed Acura RDX applications.
