I'm new here, first post. Purchased this '93 Fourtrax and have replaced CV Boot, new brakes on rear, hydraulic cylinder kits on front, general clean up, oil change & filter. Adjusted carb - runs good. 1. Downloaded Operator's Manual but no where in the manual does it tell me what lube for Front Differential and what level of lube. 2. When adjusting front brakes with wheels off floor I noticed the wheels won't turn - Full Time Locked 4 wheel drive? Thanks in advance to anyone who could give me this information.
