Trigger is locking up and wont shoot. seems like lever in front of trigger is moving out of place . does lever go on top or under trigger ?

SOURCE: front end will not lock in 4x4

if you crawl under the vehicle, trace vacuum lines to transfer case they terinate in a group of 3 (vent, vacuum from engine, line to actuator diaphram under battery) . Mark lines (bundle should have a pin to prevent bad replacement, but be safe) pop 3 hose unit , unscrew switch (count the turns to return it to same position). Transfer case side has a ball that should detent fairly easily. If stuck, work it loose or replace the switch. This manual detented switchsimply routes vacuum to diaphram which pulls cable to front axle, or vents it to atmosphere when in 2wd.

You should be able to feel if diaphram is pulling in when in 4wd and is relaxed when in 2wd mode to troubleshoot. Direct vaccum to diaphram line to test. I have used aquarium airline tubing and airstone manifold to provide quick fix when a garage and/or access to parts was not available. You want to be able to direct vent to diaphram for 2wd and engine vacuum to diaphram for 4wd.

Hi, if your steering wheel does not lock into position when adjusted, then you have a disengaged Level which needs to be engaged back in place..
Remove the plastic housing from around the steering column and ignition area. It is held with screws from under the column area. There are two screws from the top that you may need a short screwdriver to reach. Some are phillips and some are hex head. Just take your time it will come.
Once open you will see interlocking teeth or "gears" on the top of the column. One in mounted to the column the other engages into the tilt release teeth. This is the tilt mechanism. The top lever is lifted up by the adjusting lever. When the teeth are disengaged the wheel can be moved up and down.
Look to see the linkage is intact from the lever to the top gear. Pull the adjusting lever to see it is working and trying to lift the top gear up.
Note that while working you should have the negative cable removed from the battery. You do not want to trigger the air bag or damage the electronics. With the negative cable removed you will not have a problem.
