How are your u-joints, carrier bearing, and driveshafts? I found a bad injector on my truck over at Haggai's doing the bubble test with the key first then by hand. When I was barring the engine I could get it to turn but then it would get really hard to turn like almost you're gonna break something tight and note where it got tight pulled out said injector sure enough it was dripping quite abit from the tip when held upright after holding it 90° from the ground when removing the injector..
