93 GC 4x4 shift lever issues, linkage
Just a couple days ago I bought a 1993 Grand Cherokee Laredo with the 5.2 V8. This is the first Jeep I've ever owned. Its got its share of irritating issues, but it runs and drives really nice.
The Jeep is full-time 4x4, but there is a 4x4 shifter lever that has 3 positions-- full-time 4x4 (shifter forward), neutral, and 4x4 low (shifter back). I was having issues with the 4x4 lever, it was stuck in the full-time (forward) position and would not move no matter what I tried. So, I jacked er' up to take a look at the linkage. I found that a cross-pin in the linkage had slipped out of its support on one end--- this cross-pin is supported on one end by a bracket on the frame, and on the other end by a small hole in the side of the trans case. The cross-pin had somehow come out of the hole in the trans and slipped down, locking up the linkage. I was able to get the pin back in the hole and pryed it over to seat it in the hole. Then I lubed up all the pivots and joints with grease. Now the shifter lever was working and I could shift it through all the positions just as slick as snot on a doorknob. I started the truck, put the trans in neutral, and pulled the 4x4 lever into the neutral position very easily. When I tried to drop it further back into 4x4 low, it gnashed the gears sumthin' gnarly....... so I gave the lever a sharp forceful snap and CLUNK, it dropped into low. I drove the truck around my backyard for a bit (I have an acre of property) and could easily tell it was in 4x4 low. So I stopped the truck to put it back into full-time, and again with the gear-gnashing unless I forced it in with a quick jab. Then I decided to give the whole process another go, just to make sure all is well........ but it wasn't. Again, the 4x4 lever was stuck just like before. A quick inspection of the linkage revealed that the cross-pin had slipped out of the hole again. I put it back just as I had done before, and now the lever rakes through the 3 positions like butter so long as the truck is off and I'm not actually engaging the 4x4 low.
So, whats the deal? I can sit and pull the 4x4 shifter lever in and out of all-time to neutral to 4x4 low all day long, as long as the engine is off. But as soon as I start the truck and actually try to engage the 4x4 low, that damn pin pops out. What the heck?
My other question: is the gear grinding when going in and out of 4x4 low normal? Are you supposed to force the lever into position past the gnashing?
Thanks for any help!!!
