My starter started giving a dead click @ 100k and was able thru a very reliable parts house able to obtain a contact kit for under six bucks. Disconnect battery, remove wires from starter, use 10mm 12pt box (short due to swing room) and a lot of muscle as they have loctite on the three very hard case bolts to remove starter, lay a clean rag on tailgate and remove plate that houses contacts. Make sure you take note of how it comes apart. You will most likely find the Hot contact will be eaten down too a nubbin. I do about 30k per year with a lot of starts and I consider 100k very good for such a cheap fix. I put 250k on a 90 chevy p. u. and went thru 5 starters under same conditions but I guarantee you chevy starters and the one in your truck dont compare in price. Hope I have helped. PS. : I had my start problem for about two weeks before I got around to fixing problem.
