my starter just hasn't been right since the flooding last november. add to that it's a made-in-japan reman...
Was it under water, if it sat in the water or even got water logged that can ruin a starter do to rust quickly building with the repeated heat. The rust internily that shorts out the starter.
The DB starter is a gear starter, twice the size of the original but your truck being a 4x4 like mine will have no problem fitting , being a gear starter it uses half the voltage and spins at least 3 times as fast as the original. Great warranty as well although I've heard no problems with them or mine yet.
My guess is the starter is loose, the bendix on the starter is worn, (that's the little gear that makes contact with the teeth on the flywheel) or you have some teeth worn out on the flywheel. Those are my guesses.

Make sure the starter bolts are nice in tight as well. Lots of torque there.

good luck
maybe i got it backwards but wouldn't a worn bendix give me a more consistent no start? took me four tries this afternoon before she fired up, and i think everything is bolted tight enough (wanted to rule that out first)
i guess friday's paycheck is already spoken for... :/ either a new one from napa or that high torque one...gonna start a new thread for some more input
Ok, the grinding noise is the starter solenoid not forcing the bendix far enough to engage the flywheel.The solenoid is a big electromagnet.When activated it is supposed to engage the little starter gear with the flywheel.As mentioned in an earlier post the little wire that comes down to the starter activates it.As suggested running a new bigger wire would allow better current to better operate.That being said make sure your batteries and charging system is up to snuff.Weak batteries is less voltage to operate on. Mentioned before also was the arcing when bench testing,each time it does this it reduces voltage do to a dead short.Any voltage drop can shorten the strength needed to activate the starter.Remember each time you are starting the truck your glowplugs are also working,straining the system.I really think you need to change the starter,then charge your batteries on a long slow charge- overnight.
Your solenoid is failing(losing magnetic strength) this is what operates the bendix.The bendix is like a vertical teeter/tooter.The solenoid activates and PULLS on the top half and forces the Bottom half into the flywheel to starts the engine.
the solenoid is brand-new too...grrr...i'm starting to wish i had just replaced the entire starter in the first place. i guess i will have a spare solenoid now. was hoping to get this taken care of, but the weather went downhill and we're holed up inside! (see new thread!)
I had a problem burning up my starter on my 85 cause of bad luck with used injector pumps so I finally broke down and went to Oreilly's and got me a gear reduction starter with a lifetime warranty. Had to replace it two more times but those times were free. I look at it like this, I can spend $120 on ebay or go to Oreilly's and spend $150 with a lifetime warranty.
