Yep, I'm with Dirtman...
You "can" do your own alignment if only doing that, but it's kinda tedious and can be frustrating... if you have a flat driveway eyeball it at first and maybe take a tape measure and go for 1/8" toe in at the wheel under the steering linkage compared to a similar spot measured under the radius arms on the back side of the wheel. then roll it forward about 8' then check again, then back like 15' then forward like 8' again and recheck... I bought some harbor freight wheel dollies to skip some steps...
You can get really close with this method, I honestly haven't taken a TTB or TIB Ranger or Explorer to an alignment shop, my '90 wears tires but not horrible, it's just because the radius arms aren't at a good angle and the alignment migrates. My '90 was screwed when I got it (bent I beam) and I used this method and it doesn't have any tire wear issues... But then again I'm cheap and stubborn in some ways, an alignment shop will likely get it better than the ol calibrated eyeball and tape measure alignment
