Figured you turn up lol
Nothing is wrong with it. I actually thinks it's a good filter for the price...but as we know I'm a lazy *** and I look for the longest OCI I can't get away with. Mobil 1 says there's last the longest...so far my oil tests with mobil 1 (oil and filter) where good....same result for mobil 1 filter and T6. I had both the jeep and my wife's van tested. If I find the email I'll send the test results to ya, figured you might can use them in your salad dressing oil hair treatment research
So why the Mopar P/N? Or were you just fishing for other filter recommendations?
Technically yes Mobil 1s will "last long" (I don't know about "longest" or what "lasting" is...). A big reason is the media is synthetic/fiberglass. The issue with plain ol' cellulose is it breaks down over time... Oil just disintegrates it. Everyone knows this and WIX cautions that leaving a paper filter installed for a year or more risks serious engine damage. Cheaper construction like cardboard end caps carries a higher risk of blowing apart if run much beyond the intended interval. But for only 7500 miles (how many months?) a proper well built cellulose filter is totally fine. Don't need fancy shmancy stuff.

I was just curious lol. My end goal is to call mobil 1s 15k mile life on the filters and oil to see if it's really worth it. Soon as I get my stroker done and broke in I'll run it and send it off for testing. Once that's done I'll try T6 with the same OCI and compare results. Of course, 30k miles will take some time to hit. I figure 1.5-2 years, but hey...I got time lol

2WD front end
No idea what USA road standards are as I don't live there lol.
I don't see why the diff would be considered "hanging"... it's already there, you're not releasing anything from it. Removing the DS will not in ANY way create a hazard or change any geometry relating to the axle.
Anyway regarding cutting the diff housing out, I suppose what you could do is cut out the housing completely and replace it with some tubing. Real DOM, not pipe. The axle is cast iron so welding can be a challenge. At that point a safety inspector I'm sure would seriously question the integrity of the modification.

removing the DS creates a spinning hub at the bottom of the the front differential correct?
THAT is illegal under the nz regulations. all modifications MUST be checked by an engineer and stamped to proved that they are safe $$$$ out of my pocket. i want to avoid this.
i just want to see how the 2wd front end mounts so i dont have to make anything if i dont have to. what would be ideal and what i need to know is does the RHD steering mount in the same places as the LHD?
i do not need a debate of how to re-invent the front end. otherwise i would import a 2 door and hot rod it with mini tubs and a 360 v8 for noise.

2WD axle is identical to the 4WD model in mounting. Between LHD and RHD the axles are completely the same - just the steering is flipped.

Probably the U joints in the axle or drive shaft itself. Get the Jeep up on axle stands, crawl underneath and try turning moving parts by hands. Lateral movement or any slop in the U joints is bad, as is any grinding, binding, or jerkiness.
The wheel hubs are checked in a similar manner, you can grab the tire at 12:00 and 6:00 positions and try shaking it in and out. If it moves on any direction that is not the normal driving or steering axis then the hub is toast.
Grease dries up... Happens.

Alright thank you, that's a big help. Looks like I'll be crawling under and check all the u joints and the hub. Hopefully it's not all of it. Thanks again for the help.

A guy is claiming his 231 t-case doesn't have part time and i told him yes it does, you should have a light that says "part-time". Says he doesn't have one and i said that he should. I didn't know he had a 99 so i took picture of mine but mine is a 96. Just a little different lol

^^ Probably has the two transfer cases backwards. Most PART TIME lights don't work and the NP231 bezel just says 4H. Buddy probably assumes that "part-time" 4WD means it's only engaged sometimes and "full-time" 4WD means it's ALWAYS enaged. Pretty reasonable and I think a bad decision on Jeep's part when they labelled them backwards.
