hey i just hit a problem with my 4wd. i recently noticed that i was getting stuck and my 4wd light wasn't coming on so i took the vaccume acctuator off and cleaned it. i put a vaccum tester on it and it started moving but it was stiff. i put it back on and the light came on. when i went to test it out it didn't take long to notice that only the back tires were receving power. the light was on and the drive shaft was spinning but the front tires wernt moving.
any advice would be helpful and i hope i don't have to replace the spyder gears but what has to be done has to be done.

 

sometimes the check ball gets stuck,will not let vaccum to front diff. replace the actuator, check for vaccum at front diff. this should lock in the front diff. bubb

 

yeah i got vaccume at the diff. but in order for the light to come on the actuator has to engage. but for starters ill probs replace the actuator.

 

get a pos-e-loc never have trouble again

 

thats the cable actuator right? how much are they?

 

about $150-200 worth every pennie

 

just took the old one off and cleaned it and it works like a charm. ill look into that cable actuator if this one quits again.

 

Give national4wd a call (I know they have it) chk their website for the toll free number.

 

alright. i do know of a jeep store in langley that sells them for $150 ill probs wait till this one acts up again but ill definatly get the cable type next.

 

swap out the axle shaft for one with a solid shaft
