Getting new tires at Sams tonight and will follow that up with a wheel alignment. Wanted to see if there's a recommendation on the type of alignment I should get for this truck.
Is a front wheel alignment sufficient, or do I need a four wheel alignment? Suggestion on a place to get it done? (Sams doesn't do it). Approximate cost I should look for?
I have my Ex aligned at Firestone. I bought a Lifetime alignment contract. The cost of the contract does not include parts if parts are ever needed. I have the alignment checked about every 10K miles and rotate the tires every 5K miles. Wherever you have it aligned ask for a computer printout of the alignment parameters. I once carried my Ex in for an alignment and they told me it was out of alignment and needed parts. I thanked them and then went and researched the alignment process on the Ex and went back to Firestone and asked for a printout on the readings. Guess what, when they checked it this time it was within specifications. The technician said that he likes to put them "dead on". Well, I wasn't having any tire wear problems or steering problems so I opted to be content with "within specs".
. . . . . . You cannot really do 4 wheel alignment on a truck with a solid rear axle . . . . .. .
This whole thread has me confused. Not clear on how you can "align" a 4wd Excursion's rear OR front axles - they are both "solid".
Have you guys figured out a way to abuse your trucks badly enough to bend these axles? Is there some kind of "off-set" king-pin / ball joint thing-a-ma-bob that I dont know about ? I suppose it would be POSSIBLE to BEND a "solid" front or rear axle on a 4wd Excursion out of alignment, but would take some doing....!
Or are we just referring to "toe-in / toe out" checks.
My thoughts are - rotate your tires every 5,000 / 10,000 mi. and run your hand over the tread. If you dont feel or see any "feathering" , "cupping", or other signs of un-even wear, I would think you dont have "alignment" issues.
I know I have replaceable cam bushings on top that adjust the caster/camber. I cannot recall if 4WD trucks have them as well since I haven't owned my 4WD Excursion for a while.
Camber on a solid front axle is the bend of the beam itself. We actually bend front axles on big trucks all the time. Adjusting casting on a solid front axle requires putting shims under the front spring pads. Caster is adjusted on both sides to obtain a suitable cross caster.
