hey,
my damn four wheel drive isn't engaging. I've followed all vacuum lines and cant find leaks or anything of that sort. could it be my transfer case switch? or should i just invest in the 200 dollar manual engager?

 

If yours is an 86 like your profile says i would look at the motor that engages it on the passenger side of your front axle they have a tendency to go its a ring that slides over and locks the axles in you can open it and slide the ring manually and leave locked all the time. Check this out this should helphttp://jeep.zerok.ru/index.php?page=142

 

pull the weak *** two piece shafts and get a set from a TJ along with a block off plate and call it a day. the VAC system is pointless and worthless with the NP231 or 242 cases.

 

Here's my two cents.....get a bigger hammer...Hahaha jk. Well I'm not sure what the prob could be. Check the fluids

 

I agree id invest in the manual locker

 

the vac lines were messed up from the guy owning it prior to me i too of the engagement motor that slides the gear over into 4x4 it worked and all until i went into the woods and then it just didnt work. said it was in 4 but wasnt. im gonna invest in manual locker. But now it wont start i turned it off in the woods and now it will turn over and rev up to 3000 rpms but then choke and die???? about to push it off a cliff.

 

(Off topic: Sounds like my 1980 vet...find one problem come up with an answer then u find 6 more problems) best of luck though never came across a problem like that so I have no idea

 

Did you check you vacuum line's in the pass side on the firewall there or like 3 or 4 color lines there maybe one pop off or something check on that. and the color are red yellow and idk what the other ones are haha.

 

no when i had the motor off the axle it engaged into and out of four like it would in the axle but once i put the motor back into the axle and bolted it down it didnt engage anything???? maybe gears arnt lining up?
