Alignment Shop

Now that you mention the $$$ difference I can add this. Some chain tire outfits, and I will emphasize "some", will only check and adust the Toe because the Caster and Camber can be too complicated. The E350/E450 require either adjustable OR a selection of fixed Caster/Camber alignment sleeves in order to change the caster and camber. An example of the adjustable sleeves are the Ingall 59400s but they have a limitation. The limitation is you must rob from Peter to pay Paul. If a unit requires a lot of CAMBER then there may not be much CASTER adjustment available. It appears that a light front end results in a lot of CAMBER adjustment being required not leaving much for caster adjustment. For the purpose of handling stability more +caster is good. The Ford specified range for caster is about +1.5 to +7.5 degrees. You want to have at least +5.5 caster (or more for a lighter front end) IMO.

So, if the $300.00 gives you the full meal deal then it is worth it. If the $65.00 deal is a tweak of the TOE and the rest (CASTER and CAMBER) are "good to go" then it is not worth the $65.00 IMO.
