Technical Details of the Dorman 986-448 Drive Shaft

This drive shaft features a 58.5-inch compressed length and a 2.5-inch diameter steel shaft, providing a robust and reliable connection between the transmission and the differential. The shaft ends include a transmission yoke on one side and a flange on the other, ensuring compatibility with the driveline components of Scion 86, Subaru BRZ, and Toyota FR-S vehicles. Universal joints are included to accommodate angular movement and reduce drivetrain vibration, while the absence of CV joints and axle nuts means these components must be sourced separately if needed. The shaft wall thickness of 0.083 inches balances strength with weight, and the regular grade type is designed for everyday driving conditions without requiring grease maintenance.

Compatible Vehicles and Common Applications

• Replacement for worn or damaged drive shafts on Scion 86 models
• Restores driveline function in Subaru BRZ vehicles experiencing vibration or noise
• Used in Toyota FR-S to maintain smooth power delivery from transmission to rear axle
• Addresses issues such as driveline clunking, vibration, or shaft imbalance
• Suitable for vehicles requiring a drive shaft with transmission yoke and flange ends

Installation Notes and Tips

Ensure the drive shaft length and end types match your vehicle specifications before installation. The Dorman 986-448 does not include axle nuts or grease fittings, so verify if these components are needed separately. Proper alignment of the transmission yoke and flange ends is critical to avoid driveline vibration. Since the shaft length is fixed and non-adjustable, confirm the compressed length of 58.5 inches fits your application. Professional installation is recommended to maintain driveline balance and performance.
