Keep in mind of one thing. It may not be as simple as taking them out and putting new ones in. If your existing bolts are somewhat rusted, getting them out will not be easy. If they are rusted in, you are looking at hammering them out (do not hit a bunch, you will bend the bolt) or they could maybe be pressed out by a hand held press.
If they are really rusted, you are cutting the a-arms off with a sawzall and replacing them.
I see you are in Wisconsin, so you are exposed to salty roads in the winter. Depending on the age of your truck, you may have some rust build up. I also see that you are a 2005, so, good luck man. I am an 06 and my bolts were practically welded fast by rust.
If they are not rusted, piece of cake
Thanks,
