i changed out the shaft bearing assemble and when it put the 1 1/4" nut back on the bottom i put abit of beef on that small thin nut, so it would not loosen up, the shaft still turns but is it possible i got it to tight? it is getting f52 and f 72 codes. if so i will  take the rotor and stator off and loosen that nut and put a drop of red Loctite on the thread and retighten it just past finger tight and let the Loctite dry some and put it back together and test it again
