Common Problems This Part Can Address

• Vibration from a bent, worn, or out-of-balance driveshaft
• Clunking or driveline noise from worn joints or yokes
• Loss of driveline smoothness during acceleration or cruising
• Damage from corrosion, impact, or failed original shaft components
• Service issues caused by a shaft that no longer matches OE dimensions

Installation Notes and Tips

Verify rear-position fitment before installation and confirm the compressed length of 59.625 in matches the original driveline specification. Inspect mating surfaces, flange condition, and related driveline components before mounting the replacement shaft. Because this assembly is pre-balanced, avoid adding weights or altering the shaft after installation. Confirm the vehicle build date for 2011 Ford F-150 applications, since coverage begins on 9/19/11.
