this happens rarely but becoming more often.. sometimes when i turn the key the starter will make a grinding noise, as if you where starting it while the engine was on. then i stop cranking and try again and its starts fine.

i recently changed the battery because the old one couldn't hold much of a charge and i was often stuck trying to starting with very low battery power and would rarely get it started.

Could this be why this is happening? or something else?
2004 5.4l f150

 

NOT SHURE ON THE TRUCK
but on the lawnmower when it was grinding half the teeth were gone off the starter

Tighten the top bolt, then the others - prolly to late

 

ouch if that's the case that sucks (is it under warranty??)

 

i have encountered the same problem on my 2000 F-150 5.4L have put 2 new starters and a flywheel in and have seen no longterm results
