I did the rear shocks in my 94' F150 4x4, I only did the rear so far because they did have a nother front shock at Auto Zone.
You need for tools-
Hammer(Rubber Dead blow, but a framer works too
Do not cut the wire on the shock yet!!!! Its there to keep it compressed until you put it in!!!
Don't use an impact gun! Only do one side at a time, incase the jack slips on something happens you can lower the truck.
1. Put the parking brake on and jack of the rear of the truck, I did it at the bumper. Jack it enough to were the tires are not off the ground but most of the pressure is off the shocks.
2. Loosen the lower shock bolt and remove it, the shock will stretch out more after you remove it. Then loosen the nut at the top and slide the shock off.
3. Take you new shock and slide the top on first and put the nut back on finger tite.
4. Then line the bottom of the shock up with the lower mount, have the bolt in one hand and snips in the other. Then cut the wire, drop the snips and grab the shock and guide it in place and put the bolt in quickly!
If you don't get the bolt in and the shocks extends all the way, I dont know what to do except go back and get a fresh shock saying something was wrong with it
5. Put the nut on the bolt and tighten it up, then tourque the lower first to 65 ft/lbs (This is what my service manual said, you may what to check and see what yours says), the go to the upper and tourque to 55 ft/lbs. (This is for the F150 only, the 250's and up I think are like 200+Ft/lbs)
6. Repeat on the other side and lower the truck and your done!
I will add how to do the fronts once I get my front shocks in. I did'nt take any pictures because I did'nt think of this till I was done doing it. If you guys have any question ask!
