4WD not locking. Help!!

Anyone have a problem locking their 4lo into gear? Mine popped out and won't stick nor will the light indicator work. I went under and popped the linkage into 4lo manually but then it slipped out once i started to ride.

Was the linkage still connected to the transfer case? You can disconnect the linkage and put it back into 4lo. If it pops out again then it's not a linkage problem, if it doesn't than it's time to make some adjustments.

Yes linkage was still connected to the transfer case. From the shifter to the spring loaded stop on the frame then the half moon coming from the transfer case then to the actual linkage inside the transfer case. If it's not the linkage what else would it be?

Have you done a body or suspension lift since the last time you used 4lo successfully? Even if you haven't I would still lean towards the linkage and not the transfer case. Honestly, I don't know what problem in the transfer case would cause your problems. Worst case you could pull the case and open it up.

Yes a 3" BDS lift and a transfer case drop but I've used 4lo successfully after I installed it. It was a pain to pop into gear but I was able to get it but now I don't know why it wasn't working. I haven't taken a hard blow wheeling that could've messed it up

If you were having a problem before than I would say it's your linkage. A lift and transfer case drop are a definite case for out-of-adjustment linkage. There are a few good write-ups on how to adjust your linkage on this and other forums.

If it will make you feel better, just disconnect your linkage and shift the transfer case by hand and it will prove where the problem is. After a lift, tummy-tuck, and manual to auto swap, I gave up adjusting the linkage and just went to a Novak cable shifter. No more problems with 4lo.
