The front and rear bushings always wear out and are hard to detect. You can not just slide the armature into the bushing and rock it. The fit needs to be perfect. Very common problem in the "won't crank when hot". If it does not have new bushings then it is not rebuilt. NOS rear plates with bushing installed are available. Front bushings are easier to replace as they are not blind like the rears.
Ditto. A fresh starter always makes a big difference. The larger gauged 6 volt battery cables are necessary too.
