Enjoy this...jack up truck, remove tire, remove plastic cowling and expose front right wheel well.you may want to wash this side of engine at this point. Remove battery cables, remove the 13 mm nut and 8mm nuts on the solenoid. take a 15mm socket and remove the upper aand lower holding bolts. Use an extra long extension for the lower bolt. Ratchet out in front of the A-arm. Dislocate the starter from the fly wheel side of starter. wiggle,jiggle and point the starter gear at a 45 down and PULL starter out and down.
