Hello everyone, I'm newer to the forum but have used many of your threads as some solid guides to help out with my comanches. I have seen many threads about this topic before, but none of them cover exactly what I need or want. With that being said, as the title states, my 4WD is not engaging.. Took it to the dunes the other day and noticed that the T-Case would engage but not the front axle. I narrowed it down to the shift fork not locking the axle into 4wd. I have seen many videos and tutorials/guides on how to do a CAD delete and just manually lock it in so it never fails again, but I have been told this also engages the running gear and will cause more friction and wear down the road (not to mention take my MPG down a notch or two). So, I'm guessing its the vacuum lines that aren't working, but I'm having a hard time finding where the lines go from the front axle. Anyone have any ideas where I might be having a leak/where the lines are going to? Also, the jeep overheats when I put into 4 Low and drive it for a bit... And before I forget, I have three 1988 jeep comanches, all 5 speed manuals, all 4.0 inline 6's, all relatively stock (bought them all used). The one I'm working on is a 1988 jeep comanche base model, 4.0, 5spd, AC/Heat, NP231 Command Trac transfer case, 153k miles. Thanks guys.

My clutch master cylinder was at one point leaking on to my fuse pannel. I took it apart does not look bad some corrosion not much. The question is can it be cleaned or do I need a new fuse pannel? If it can be cleaned whats the best way?

After installing cd player the gauge cluster lights quit working. The p.o. had cut the harness out so i had to straight wire it in. the cd player does not have constant power. They were working fine before but quit after wards. Nothing else quit working. Did i connect the wrong wire?! The cd player doesnt have memory so it starts over everytime and no presets. What the heck did i do wrong?! I checked the fuses and all were fine. my fuse box is a little messed up (which i need to get around to doing) but nothing else quit
