My 4wd won't disengage on my 73 712M

Post by mopar »

My 4wd won't disengage on my 73 712M. The first lever is up and the light is lit. I tried to pull the lever down and it feels like it hits a mechanical block half way. When I open the bleeder I can get the lever to go al the way down when it goes back up it I get the same problem again. I have flushed the hydraulic line with over a qt of Dot 3 and it is pretty clean. I disconected the slave cylinder and went forward and back a few times still wouldn't disengage. The truck was like this when I bought it. I only drove it about 1/2 mile in 4wd.
Question #1 what can I do to get it out of 4WD.

Question #2 is will it harm anything to drive it on the road(blacktop) with 4wd engaged to try and get to disengage.(Thinking of changing the fluid in 4wd case with some new stalube GL4 and then driving with the slave out of the case to see if the 4wd will unlock)

#3 Can I disconnect the slave cylinder and the switch on the other side and unlock manually somehow or does the box need to come out and opened up.


Any help or suggestions will be greatly apreciated.

Thanks from a new pinz owner

Mopar,

No offense please, but this ought to have been posted in the "Drivetrain" section of the forum.

You might also try searching that forum, as others may have already had this problem, and you might solve your troubles w/o someone else helping. Perhaps you've already tried this, it can sometimes be difficult.

Lastly, by posting your problem in the appropriate forum section, it's more likely to be found by someone else in the future with this issue, and help them.

Try this one:

I searched for "won't unlock" and that was the first post listed. If this doesn't solve the trouble, post it in the other section please.

BTW, I would not recommend driving it on-road "locked".

I have searched and saw that thread and a few others that is where I got the ideas for what I have done already.

My diffs aren't locked its the transfer case for the 4wd.
