First time posting...I am having a problem with my starter on a recently bought CJ7 (4.2L, T-5 tranny, towed to the house). When turned over it makes a awful grinding noise (almost like engine is started already but isn't), and it takes several times of this to start up if it even does. I changed out the starter because I thought it was bad but ended up being the battery. The old starter had metal shavings, when the new one was removed it also had metal shavings. When the flywheel was inspected, some teeth are worn on the engine side (teeth leading edges rounded, some are chipped) but nothing major. I had to retap and put a helicoil in the starters bottom hole on the tranny due to being stripped out so I replaced the bolts also. The replacement bolts are not fully threaded and I put lock washers on so the bolts won't back off. I can upload pictures tomorrow in the daylight. I am at my whits end and can't figure out what is wrong. I have replaced the cables, starter, battery and starter solenoid. I even sanded the plate where the starter mounts to try and give it a better ground...Please help me, and thanks ahead of time.
