Ok I have a few questions before I take the trip back to school in a few days.
I've done some research but please chime in with any info or things I have missed.

1.The transmission clunks pretty hard into drive, and there is a delay when I put it in Reverse. I'm not too concerned, its an old JEEP...just want to make sure it's not a sign or some bad transmission woes. From what i've read the most likely culprit is the rear U-joint or the tranmission bolts themselves?

Does that sound correct? or is there anything else I should check.

2. There is a little bit of rattling sorta sound coming from right below the shifter, especially heard at N and P, but also can be heard when taking off in Drive. If I jiggle around the handle for the 4WD i can make it stop (if i hold it in the right spot). I havent had a chance really to climb under this JEEP since I've had it...but what should I look for under there to fix this?

3. My Parttime 4WD does not show on the dashboard, as the fulltime does. Any relation to problem #2? hmmm. Also Its dark out now but tomorrow...I wanna check if its actually going into parttime and its just the light, or if its not at all. I know how to check for fulltime, but whats the best way to tell if im in parttime?

4. Oil pressure is right below 40 when I'm at idle (maybe close to 35), and in the higher 40's when I'm driving. Haven't noticed any leaks yet. Is this normal?

5. I also seafoamed today and did it through the BB (I took a video, it will be in my 'soon to be made" build thread). And there was a decent amount of smoke...but I heard going through the BB only gets the back two cylinders? Is this true?

If you guys can answer any of those questions or point me in the right direction It would be very much appreciated

1: Yes, check driveshaft for play. Of course you dont have a year listed so I cant say much, but the AW4 manual says a 1-2 second delay for shifts into d/r is normal.

2: Tcase handle Rattle is normal, it was fixed in later years (99?) Try adjusting the linkage

3: Pry just the switch, a 15$ part and a 20 min job. Jack it up (both ends) put it in 4wd/trans neutral, and turn the tires. All 4 (or at least one front, one back) should turn.

4: Yes

5: No idea...

6: Its not a "car", Its a JEEP.

OOdynamite

4. yes, that is normal

After driving this battle tank for over a year and calling it the jeep:

for number 2, theres a TSB out there on this, chrysler whent indepht on it. they fond out that the trans mount was the root cause problem... by puting a new would make it stop..

Fresh
