1) in front axle
2)Placed them about 6" in front of the axle
3) I didn't use a TQ wrench, just till I had them tight and the assist spring under load 4) Shocks - Standard/Stock Shocks
5) 4wd
6) Cab style and bed length- Extended Cab/ Standard Bed 7) empty bed 8) The springs seem to have definitely helped, truck seems soother at all MPH but it did not completely remove the vibration i had at 60-75mph. I'd say it was about a 80% reduction. 100% WORTH IT and a lot better than it was 9) I did not try in rear of the axle but my truck does have the Max Trailering Package so idk if i have different shocks or rear leafs in the back compared to a standard truck
