Do you guys do a 4 wheel alignment on your ARR's?
or would just the fronts be ok....

 

Are there 2 wheel alignments out there?

shops will supposedly perform a "two-wheel" alignment, but that's not the proper way to do an alignment. To properly align the car (set the toe) you have to align the rear wheels first, and then the fronts are aligned off the rears. If you watch a car being aligned with the sensors attached to the wheels, when the rear wheels are adjusted, the readings for the front wheels will actually change. So always have a 4-wheel alignment done.

 

i do alignments for the shop that i work for and we only do 4wheel alignments. like the other guy said the front is based off of the rear tires. that angle is called the thrust angle or thrust line and basically is the direction that the rear points. if the rear is not pointed in the proper direction your car can dog track which means that the rear will be slightly off from the front and will look like the car is going sideways down the road.
hope that helped
