It's easy as hell, cept the bottom bolt... I suggest taking the two bolts out of the front part of the wheel well liner, folding it backwards across the front tires, and then reaching that last bolt... It's gonna be by feel on that last bolt
There are a ton of options out there, but OEM is best. As I have learned from customers and my kids trucks, the ones that work best are NOT the cheap **** on eBay. The las truck I built(shown many times) is my kids and the front and rear set were $450. They work great but stock was like 200.
