If you crawl just under the front of your truck there is a LARGE bar that connects your two front wheels and located toward end by drivers side front wheel are three items on the bar
1 large turnbuckle, 1 large nut on EACH end of turnbuckle. Make sure steering wheel is perfectly centered inside cab. If it isn’t perfect loosen nuts on each end and turn the turnbuckle to straighten steering wheel.
Once it’s perfect back the nuts off about 3 or 4 complete turns then put red Loc-tite on exposed threads, tighten nut back up and do the other side the same way. I just bought two small pipe wrenches from Walmart and a little short sledge hammer from them. On a scale of difficulty it was a 1 on 1 to 10. If you are not sure someone may have a pic, if not I will take one today and post this evening.
