"Steering wheel not straight" is easy to fix yourself, and it's usually caused by toe not being set correctly. You will need a 13mm open-end wrench and an adjustable wrench (or whatever size open-end wrench fits on the tie rod lock nuts).
Find an obstruction-free, level surface to park on. As you park, straighten the steering wheel. Try not to turn it after you've stopped.
Get out of the truck, squat down in front of the truck and look towards the back of the truck, visually lining up the front and back sidewalls of the front tire with the sidewall of the back tire. You are attempting to draw an imaginary line touching the front and back sidewalls of both the front and rear tires.
If the toe is in spec, the front and back sidewalls of the front tires should line up with the sidewalls of the rear tires. You should barely be able to see the rear tires while simultaneously seeing the front and back sidewalls of the front tires.
If you line up the front and back sidewalls of the front tire, and you can see the tread of the rear tire, then the front is toed out. If you can't see the rear tires, then the front is toed in.
To adjust toe, loosen the large nut on the tie rod. Using the 13mm wrench, rotate the tie rod until the front/rear sidewalls of the front tire line up with the rear tires. Repeat for both sides of the vehicle.
Tighten the tie rod lock nuts when done.
