Re: Periodic starter grind
The last time that happened to me it turned out that one of the starter bolts loosened up a bit. I figured that the torque of the starter would throw off the alignment and some times it would catch properly and some times it wouldn't. Also check the new bolts that came with the starter. Cheep bolts may not be sized correctly. The knurl is supposed to keep the bolt shaft snug in the starter bolt holes so the torque of the starter does not have that little movement that throws off the alignment.
