I just replaced the upper Control Arms, on my 99 Ranger XL, rear wheel drive truck, and installed a Camber/Caster Adjustment kit.
I wanted a Front-end alignment, but every alignment facility seems to offer only a 4 wheel / front & rear wheel alignment .
Is it even possible to align the rear wheels on a 99 rear wheel drive truck?

 

There is no alignment for the rear. So only the front.

 

That's what I thought. I guess they charge for a 4 wheel alignment regardless.

 

I would not pay for service not done. Talk to them and question how they plan on aligning the rear. If they give you a song and dance about matching the rear tires to the front, tell them thats BS.
