4x4 issues

I have a 95 yj 2.5 5 speed. I Have read a few posts on here about the vacuum issue with the YJ's 4 wheel system. Checked all my hoses look good no rot the lever is extremely hard to move from 2wheel to 4hi or 4 low but when I do the jeep doesn't move like in neutral but will grind a little when try to move. Please help

if shifting into 4lo, you should always be in N, but shifting into 4hi shouldnt be a problem, spray some lubricant on the linkage and work it in and out of the gears, it will loosen up some.

they have a tendency to get stiff..as suggested above,lube it good..many times you will have to push the lever pretty hard to the side before you shift it..shift it back and forth a bunch of times to help loosen it up after you lube it good

So tried to shift into 4h and it went in but not sure it engaged. The light does not come on. But my dash light do not work except the seat belt and turn signal lights. Need a new rheostat for them to work. I know 4L works shifted into it and jeep would crawl in snow. Any advice? I'm going to put on jack stands this weekend and see what's going on underneath.

The linkage has some adjustment. The bolt may have came loose resulting In it acting whacky. Get some WD-40 on the joints and check the tightness of the bolts. One more thing to check is the transfer case fluid. It could be dirty or low- it takes ATF.

EDIT: Maybe the problem could be in the transfer case vacuum switch- where the vacuum lines plug in. I had one of the 4 male ends break off in the past

I will check that out and the transfer case fluid is brand new I drained and replaced it when first bought it. The PO didn't know if any was in it

I know mine did the same thing and I took the cover off inside the jeep and I had to use PB blaster we were all the bolts were for the shift handle got that working nice and smooth while not connected to the TCase lever on the side of the tea case then I had to mess with the adjustment on the TCase rod to get for hi to engage thoroughly I did notice that moving that adjustment on the TCase rod a little bit is a long way as far as getting it right for Forlow and for high and I have a enV2 31 Tcase hope maybe that will help you

I would bet if you lubed the hell out of it, it will work. I can pull my lever back into 4HI or all the way to 4LO for that matter with 1 finger. Just takes a little TLC. And sometimes a BFH.

That's my plan for the weekend and a BFH fixes everything
