This guy has some interesting parts on Etsy. I bought these after removing the rear lift gate panel on my 96 Jeep XJ. Not only did I break all the christmas tree retainers, but also quite a few of the plastic mounting clips that are located on the panel door...

If you can't find a local rebuild shop, look online and find a source of Nippendenso remanufactured alternators in the size appropriate for your jeep. Denso has a huge facility in Maryville, TN that makes new and remanufactured parts. I got mine from this site...

Rob, It is indeed a late model 1996 with the slip yoke completely outside the transfer case. In fact, I have encountered some 1997 parts on my vehicle. I had a Jeep service manager tell me that during the 1996 switchover, if they ran out of 96 parts on the assembly line, they would grab parts...

Thanks to all that posted to this thread. I wanted to give an update, as I always hate it when someone posts a problem and never gives a final resolution. Tom was right. It was the pinion bearings. I went back to the shop that did the ring and pinion install, and I convinced them to do a test...

It is a 1996 Jeep XJ, as stated in the first sentence of the posting. All stock. The 231J transfer case has a external slip yoke which does not extend into the transfer case. It has a output bearing in the rear external housing with a snap ring and rubber shaft seal. I will try to find a...

Hello, 1996 Jeep XJ, 231J transfer case, 8.25 rear axle, While testing various things in search of a whine noise, I noticed a little slop up and down in my transfer case rear output shaft. It feels like maybe 1/16", hard to tell exactly. I don't feel any slop while pushing the shaft in or out...

Okay, so I am narrowing this thing down. No change if I remove the front driveshaft. I bought a infrared thermometer reader from Amazon and tested the differential after an extended 55 mph drive. Temps are in the 130-140 range at the pinion snout, which I think is very good. The front is in the...

Thanks for the harmonic balancer tip. I looked at it after your post and did not see any in/out motion while running, so I thought that it was not the problem. However, last weekend while crawling around under the jeep to investigate the source of an very small oil leak, which I assumed was the...

Some new information Thanks for all the replies. I took out the front driveshaft and it made no difference. The rear driveshaft has new u-joints and was balanced about a year ago. While thinking of new tests to conduct, I changed the spark plugs to RC12LYC as recommended in this thread...

Hello, I have a 1996 Jeep XJ stock, 6 cyl/4.0 engine, 4WD, AW4 transmission, 231J transfer case and Chrysler 8.25 axle, with 245000 miles. I get a rumble sound (wa-wa-wa) sound as soon as I hit 38-45 (i.e. overdrive) accompanied by a whining noise. The rumble and whine seem to disappear when I...

Possible solution from OP: Neutral Safety Switch I replaced my neutral safety switch several months ago due to no backup lights and I have yet to experience any of these symptoms. I was going to clean my old one (original part), but after finding a new one on ebay for $42 shipped, I just...

Thanks to all that replied. I accidentally found this post by another forum member who had the same question: https://www.naxja.org/forum/showthread.php?t=1049571 It looks like even at stock everything, at least an inch of slip yoke threads are uncovered. Interesting. Thanks again for all...

Hello, I have a 1996 XJ wuth 8.25 axle and 231J transfer case. After putting in Dorman heavy duty springs, my rear has an unintended 2" lift. I had to have the rear axle shimmed to align the pinion angle and transfer case angles. The guy who did the work was concerned about the amount of...

No solution as of yet. I have been concentrating money and time on my rear differential. It has been occurring less frequently. I performed step 10 as recommended by cruiser54 since it is an easy maintenance item. The downshifting at highway speed has not occurred in several months, so I am...

I will have to give this a try. I too have been dealing with some mild floor vibrations that I have been attributing to tire wear. It is worth a shot. Thanks.
