if you get up under the truck is the shift rod from the 4WD shifter loose at all or is there excessive play in the shifter itself ?
what size truck is this ?
ok and this just has one rod from the floor shifter to the case correct ? and one end is threaded for adjustment ?
ok what you need to do is pop off the rod and manually by hand shift the case solid into 2WD then put the shifter into 2WD and adjust the rod to match those rod holes and it should be perfectly into 2WD and when shifted into 4HI should fully lock into 4HI
once that is adjusted it should be fine
if by chance after that is done it still jumps out there is an internal transfer case issue causing this problem and would need to be removed and rebuilt and or repaired
if you have any questions please ask as i do not get credit for my work until you rate us here at Justanswer
you can not get the case by hand to lock into 2WD with the rod popped off ?
if you pop the rod off and its shifted into 2WD leaving the rod off the case will still jump out of 2WD ?
if the rod is off and it will NOT be in 2WD in any gates you select by hand there is something internally wrong in that transfer case
one of them should be 2WD
up in the air shift the case and two detents should allow the front drive shaft to free wheel
in 2WD it should unlock the front axle with the actuator in the front diff
or is this a full time front axle i n the truck ?
jack up the front and 2 positions on the case the front axle from the case to the front axle should spin by hand
ok sounds good let me know
