Re: Front Axle Shifting
 
Hi Nick,

The fork is clipped to a shaft the protrudes from the right side of the
cover. Weld a bolt onto the fork shaft, perpendicular to it. Drill a
hole across the bolt, parallel with the shaft. The cable (thick wire
really) runs through the hole and is held firmly in place by a nut above
and a nut below.

The cable housing is braced above the cover by a hose clamp held between
two nuts welded to an arched brace plate that is attached by two of the
cover bolts.

I used a scrounged bracket to bolt the knob-end of the cable to the
metal strip that runs along the underside of the dash. This works okay
but it has some flex so I'll probably cross brace it to the fire wall.

Push the knob home to push the shaft, which in turn pulls the fork and
collar off of the inner axle splines. Pull the cable to engage. Pretty
simple.

One word of advice: the original shift fork is aluminum. It may be worn
and have too much play on the shaft to be 100% effective. I used a spare
from a parts truck that fit tighter than my original. I've heard that
there is a steel Mopar replacement fork available.

You might also try the junk yard - my 88 MJ shift fork is one piece
steel. Might be a replacement for all I know, but what's in there is
all steel.
