Wheel Alignment Parameters
1. Camber: Camber is the angle of the wheels when viewed from the front or rear of the vehicle. A wheel that is tilted inward has negative camber, while a wheel that is tilted outward has positive camber. Camber can affect tire wear, handling, and steering.
2. Caster: Caster is the angle of the steering axis when viewed from the side of the vehicle. A positive caster angle means that the steering axis tilts towards the rear of the vehicle, while a negative caster angle tilts towards the front. Caster can affect steering stability and the returnability of the steering wheel to center.
3. Toe: Toe refers to the angle at which the front or rear wheels are tilted inward or outward when viewed from above. If the wheels are tilted inward, this is called “toe in,” while if the wheels are tilted outward, this is called “toe out.” Toe can affect tire wear, handling, and steering.
4. Thrust Angle: The thrust angle is the angle between the vehicle’s centerline and the rear axle’s geometric centerline. It is measured by comparing the direction that the rear wheels are pointing to the centerline of the vehicle. The thrust angle can affect vehicle stability and how straight the vehicle drives. A thrust angle that is not perpendicular to the centerline of the vehicle can cause the vehicle to pull to one side.

It’s always best to consult a professional mechanic or alignment specialist for the most accurate recommendations for your vehicle.
Wheel Alignment Brief Information
Wheel alignment is the process of adjusting the angles of the wheels so that they are perpendicular to the ground and parallel to each other. Proper wheel alignment is important for several reasons, including:
1. Safety: Properly aligned wheels help ensure that a vehicle travels in a straight line and handles properly, reducing the risk of accidents.
2. Tire Wear: Misaligned wheels can cause uneven tire wear, reducing tire life and requiring more frequent replacements.
3. Fuel Efficiency: When wheels are misaligned, the vehicle may have to work harder to maintain speed, which can result in decreased fuel efficiency and increased costs.
4. Ride Comfort: Properly aligned wheels can result in a smoother ride and better handling, improving overall ride comfort.
About GMC Sierra HD
For the 2009 model year, the bumpers on all 1/2-ton Silverado and Sierra models were updated, and the front fascias were shortened. Additionally, the extended and crew cab versions that were equipped with the Vortec 5300 V8 received a new 6-speed automatic transmission that was designated as the 6L80. Both the LTZ and the SLT now have access to the Vortec 6200 V8 engine option. Bluetooth was added to the list of available features and became standard on the Denali, SLT, and LTZ trim levels. On the SLE and LT trim levels, Bluetooth was available as an option, as was a rear vision camera. The Silverado and Sierra HD trucks were the first to have a trailer brake controller that was built into the vehicle in 2007, and now that feature is offered as an option on 1500 series trucks. The XFE package was brand new for 2009, and it was only available on Silverado 1500 Crew Cab LT vehicles with two-wheel drive. It includes a soft tonneau cover, XFE badging, aluminum wheels, and low rolling resistance tires in addition to the 5.3L Vortec V8 engine. (Source: Wiki)
