At it again. F24D wont move. Couple years ago had same problem and had lost a bearing in rearend. Was plowing the garden and came to a dead stop. No movement out of any gears. Get a little grinding noise in rear end when clutch is let out. Pulled top of rearend of today and bearing I replaced looks good. Pulled side cover off rearend and found a spring abou 2” long laying in bottom. Can’t find it in parts book and have no clue what it is from. Any help?
