I just made $100 with the help of this thread! Thanks!
My friend bought a 91 or 92 EB X, he picked it up for nearly nothing, one of the 'major' problems it had is the 4x4 hasn't worked in a few years....I told him I just 're-built' my 4x4 shift motor, and I could do the same for him. I removed his shift motor, pulled the red 'keeper' out of the plug using a nail and some needle nose pliers. pulled the brown center wire out, and took the motor to my house for disassembly. Sure enough, the nylon/plastic bushing was in 5 pieces in the housing. I replaced it with a small section (1/4" - 3/8" long) of rubber hose, cleaned up the motor contacts (they were VERY black with carbon deposits), lubed and re-assembled.
I installed the motor and it worked perfectly........
Thanks!
