Fr axle Actuator solenoid has been replaced 2x (failed 18mo ago; ruptured diaphragm last wk). When pressure-testing vacuum lines, leak found n curator (ruptured diaphragm); hence 2nd replacement.
Upon shift n2 4wd, can sometimes feel fr tires trying 2 bite; but no 4wd light. Other times, fr tires & 4wd light don't engage @ all. After a few minutes r miles, 4wd light sometimes comes on & stays on. Sometimes it flickers back off. When shifting out of 4wd, sometimes light takes far 2 long 2 go out.
After shifting n2 4wd when going straight & slow, sometimes hear a low clunk and feel small pop thru gas pedal like fr axle trying to engage. Usually in this case, 4wd light isn't on. But sometimes, it flickers on/off.
After shifting n2 4wd when going straight & fast, may take 5-30 minutes for 4wd light to come on. Once it comes on, as long as I maintain speed (>45mph), 4wd light usually remains on; but will sometimes flicker off when slowing down (<35mph).
Bottom line, there seem 2b NO consistencies fr which to draw a solid conclusion. PLEASE HELP!
