is a 4 wheel tire alignment required
when replacing tires is there such a thing as 4 wheel alignment or is this just a
scam by tire dealers. The rear is a solid fit unless you hit something hard
causing the banjo to move??
Yes, there is a 4-wheel alignment. Not all vehicles need it, usually the front wheels are adjusted to the rear (2-wheel alignments are 'thrust' alignments), but on vehicles that allow adjustment to the rear a 4-wheel alignment gives you more options for adjustments.
should have stated on my question that it was a 05 GMC Sierra 1500 4x4 where I dont believe there is any adjustment on the rear tires making it a scam by tire dealers saying the rear can be adjusted. If it were independent suspension that would make a difference. Thanks Ken
Most garages call it a 4 wheel alignment, because of the way KenF spelled it out. But should just call it an alignment. The rears would be adjusted if they could. You needn't worry as they will align the car to specs.
Upon further research I found that there were trucks made from 02 to 05 under the Denali pkg that had what was referred to as quadrasteer where the rear wheels turned along with the front wheels where as I could see a 4 wheel aligment being needed as they would have independent suspension so unless you have that the dealers are digging into your pockets if theyhit you with a 4 wheel alignment charge
