Part Description
This rear drive shaft was removed from a 2011 GM Trucks Silverado 2500 4×2 Extended Cab with 8-foot box, equipped with a 6.0L engine and automatic transmission (MYD option). The driveshaft has been thoroughly inspected for straightness, joint condition, and overall integrity. It is currently on our shelf and ready to ship immediately.
The rear drive shaft transfers power from the transmission to the rear differential in your truck. Common reasons for replacement include worn universal joints causing vibration or clunking noises, damaged yokes, bent shaft from impact damage, or complete failure leaving you stranded. A failing driveshaft often produces symptoms like vibration during acceleration, clicking sounds when turning, or difficulty moving the vehicle.

Frequently Asked Questions
Will this rear drive shaft fit my 2012 Silverado 2500HD?
This driveshaft fits 2011-2014 Silverado 2500HD 4×2 Extended Cab models with 8-foot box and 6.0L automatic transmission. Contact us with your VIN to verify exact fitment for your specific configuration.
What are signs that I need to replace my rear driveshaft?
Common symptoms include vibration during acceleration, clunking or clicking noises especially when turning, squeaking sounds from worn U-joints, or complete loss of power to the rear wheels. Any of these symptoms warrant immediate inspection.
How much does it cost to install a rear drive shaft?
Installation typically takes 1-2 hours at most repair shops. Labor costs vary by location but expect $150-300 for installation, making this used OEM part a cost-effective repair solution.
Is this driveshaft balanced and ready to install?
Yes, this is a complete OEM driveshaft that was factory balanced. It has been inspected to ensure straightness and proper balance weight retention, so it is ready for direct installation.
What’s the difference between 4×2 and 4×4 driveshafts?
4×2 (two-wheel drive) trucks have a longer rear driveshaft since power only goes to the rear axle. 4×4 driveshafts are shorter due to the transfer case location. This part is specifically for 4×2 applications only.
Do you ship driveshafts and how are they packaged?
Yes, we ship driveshafts nationwide via FedEx Freight. They are carefully packaged in protective materials to prevent damage during transit and typically arrive within 3-5 business days.

- Support the transmission with a jack when removing the driveshaft to prevent damage
- Apply thread locker to U-bolt nuts and torque to GM specifications (typically 15-18 ft-lbs)
- Check transmission fluid level after installation as some fluid may leak during the process
- Test drive at various speeds to ensure no vibration – any vibration indicates improper installation or damaged components
