Common Causes of Problems with the GMC Sierra 1500 HD Body Lift Kit

Nothing beats the feeling of driving a GMC Sierra 1500 HD with a great body lift kit. Aside from trimming up your vehicle when installing bigger tires, raising your body or suspension also gives your vehicle a higher profile and a rugged new look. However, getting your GMC Sierra 1500 HD to ride higher will also result in changes in your vehicle's behavior and drivability. That's why it's important to take note of the problems that you could encounter the possible causes behind them.

The vehicle's front tires are wobbling from side to side.

If your GMC Sierra 1500HD's front tires wobbles from side to side while driving, it is most likely experiencing wheel shimmy. Don't forget that a vehicle becomes less stable and more wobbly especially in sharp turns at high speeds when it has been raised higher. This problem is generally caused by misalignment of the steering linkage. However, this could also be the result of installing a new body lift kit, a heavy winch, or oversized wheels and tires. The geometry of your vehicle's suspension will be greatly affected by these kinds of alterations in your GMC Sierra 1500HD. Getting a good set of steering stabilizers will help in reducing wheel shimmy on your lifted rig.

The speedometer and odometer read slower than the vehicle's actual speed.

If you're experiencing errors in your speedometer and odometer's readings, this is mainly because there have been alterations made in your vehicle like the change in the size of the tires. These changes will cause your GMC Sierra 1500HD's speedometer and odometer to read slower than your vehicle's actual speed. It may also result to altered transmission shift points, traction control, and ABS functionality. Changing the gear located at the end of the speedometer cable usually solves is problem for older trucks. For the modern trucks, the Vehicle Speed Sensor (VSS) will do the trick.

The vehicle vibrates while being driven.

Some of the possible causes of drivability issues such as axle hop, loss of suspension damping, and vibrations are low-quality shocks and generic suspension tuning. However, this problem could also be caused by an incorrect vehicle trim height because the vehicle's body and frame is positioned away from the differentials. Adding spacers with stock axles should solve this problem.
