There are two main types of 4-wheel alignments. In each case, the technician will place an instrument on all four wheels. In the first type, the rear toe and tracking are checked, but all adjustments are made at the front wheels. This is done on vehicles that do not have adjustments on the rear. The second type is a full 4-wheel alignment where the rear is checked and found out of alignment adjustments are first made to true up the rear alignment because the front is aligned to the rear, then the front is adjusted. A full 4-wheel alignment will cost more than the other type because there is more work involved.

Misaligned rear wheels make it harder to steer incorrect direction. When the rear is misaligned, it can track and look the way a dog trots or a crab walks, sometimes a little bit sideways. Rear alignment critical as the rear wheels are used as the start point for a proper wheel alignment. If there are no rear adjustments and rear is misaligned, it will require the installation of aftermarket shims, adjustment bolts with eccentric cams if available. If aftermarket adjustment components are not available for applicable model or vehicle is so far out of alignment that available components do not have enough range to get back into manufacture specifications, then components likely bent will need to be replaced such as control arms, tie-rods, spindle/knuckles, struts. The same is true for the front. In worst cases, sub-frames or cradles may need to be replaced or vehicles require to be put on a frame machine and repaired at the body shop. Aftermarket adjustment components require additional cost that can vary, but normally nowhere near as much cost if steering/suspension components require replacement or frame repairs required.

Over 50 million vehicles on the road today require a reset/recalibration of the steering angle sensor (SAS) following a wheel alignment, as instructed by the vehicles manufacturer, on certain vehicles equipped with Electronic Stability Control (ESC). Calibration of SAS is also an additional cost that can vary by manufacturer, which can be as low as $20 in combination with alignment and must be done whenever SAS is replaced.

The steering angle sensor (SAS) determines the position of the steering wheel, where the driver wants to steer. Located within the steering column, the steering angle sensor normally has more than one sensor often packaged together in a single unit for redundancy, accuracy, and diagnostics. SAS initially used on conventional mechanical steering systems to assist, but now with many vehicles that no longer have a mechanical power-assisted system and now use completely electronic power steering (EPS), sensor calibration and function required for any operational steering.

ADAS stands for Advanced Driver Assistance Systems – the active controls built into vehicles, vans, and trucks. Some manufacturers started to offer Advanced Driver Assistance System (ADAS) options as early as 2005, with some active systems that could affect steering, braking and cruise control in 2013.

On most vehicles equipped with ADAS features, calibrations will need to be performed after that alignment. ADAS calibration can be as low as $20, and for a few models as much as $800. Currently, some dealers and most independent repair shops have limited or no ADAS calibration capability especially when specialty targets and as much as 58 feet of clear shop space required. Carmasters has invested in our ability to properly service our customer's vehicles and can calibrate most ADAS systems.

BMW and other manufacture alignment specs may require a specific weight in each front seat and the trunk as well as a full fuel tank. The exact amount varies depending on the model. There would be if required additional cost to fill fuel tank and place weights in vehicles.
