Thank you, sir. I was looking at that and thinking I would have had to use an adapter pipe between the flange and the cat. I just ordered a new one with the flange on it to save the headache. I've had several 1995 YJs and a 2000 XJ all without the flange. First time I've come across it. It looked to me like the part numbers with the flange only ran through 1992 for all compatible Jeep models, so I assumed Jeep made the change then.

That's exactly what I need. Thank you. Do you have the number handy for the rubber isolator for the AX-15 trans mount too? Might as well do both while I'm there. I just ordered a Magnaflow 23229 which has the flange on it. My research shows you either need a direct fit unit like what I ordered, or you need to extract and weld on the flange to a universal cat like the 91005. It looks like Jeep dropped the flange line-wide for the 1993 model year.

I removed the catalytic converter from the MJ. It's internals are toast. Looked good from the outside, but inside all the elements were cracked, apparently in many pieces inside, and it was belching dust and pieces upon removal. Shaking it just a bit after removal reproduced what I was hearing. I ran the MJ without it in the exhaust, just dumping right behind the downpipe, and the noise was gone. So I'm fairly sure this was the culprit, a catalytic converter with destroyed internals. So I'm going to replace it, but have run into a bit of an issue. The stock cat has a square flange on the input side that isn't on the new cat I have. The new cat I have, that I was going to use for my YJ, but maybe could use here, is a standard Magnaflow 91005, with a standard 2.25" input/output, without a flange. So I'm going to have to research that and figure out if I need to get a different/new cat specifically with an XJ/MJ input flange, or if I have to use a cat like I have here, and need to cut the flange off the old cat and weld it or clamp it to the new one. Any input would be great there. Also, there is excessive play in the bushing through which the exhaust mount passes (the other half of the square flange on the downpipe, part of the transmission mount). I think that at times the downpipe could contact the transmission crossmember with the amount of slop there. Does anybody have a part name or number for that bushing, or a new set for the transmission mount? 91 HO AX-15 transmission mount and exhaust mount bushings, I suppose. Again, any pointers are appreciated.

I've got a new one here for my YJ build that I can reappropiate. Might do it today and see what's what.

I'm getting noise but not noticing any power issues.

I've got a 91 HO 4WD MJ with the 4.0L and an AX-15. The truck has 231K miles on it. I've owned it for a little over a year, and every time I've ever started it, it starts making some pretty bad noises here and there for a bit. I think it's the catalytic converter being clogged up, but am not totally sure, as I've never had that issue. Basically when I start the truck, and for about 15-20 minutes, until the truck is sufficiently warmed up (and in my mind the exhaust is at temp), the truck makes an intermittent noise that sounds like it's coming from the catalytic converter area. This happens when parked, as well as in motion. The noise could be coming from the transmission or engine's bottom end, I can't track it, even with an automotive stethoscope. The noise comes and goes and the best way to explain it is it sounds like a shudder running through the whole system with some clanking and other commotion. Banging on the catalytic converter seems to effect the noise somewhat when it's happening. After a while it just goes away and the MJ will run/idle happily for hours. It looks to be the stock cat. So what are your thoughts? Would a clogged cat cause excessive noise? Would the sound dissipate as things got hot? Thanks.

You already know I'm in for a set of rollbar brackets. Thank you.

April 2018: New Emergency Brake Cable and Getting to Work Happy one year anniversary! I really needed to get the front emergency brake installed to continue work in the yard. The old cable snapped last summer and I really needed it repaired to park on some of the steeper grades. I was prepared for the emergency brake cable install to take a while after reading some horror stories in tech. A 13mm wrench and about 15 minutes was all it took. It was the front cable that runs to the pedal that got replaced. Guesssing I got lucky. The carpet was out but the bench was in. Then the MJ got put to work. The pines took a beating during the recent storms. Cypress tress didn't do much better, either. They'll be cut up and chopped later. Heavy wood hauled all over wet steep grades with no issues. I really love this truck, and I can't wait to get the build started. It sat six months, and started right up, and ran hard like a champ for half a day. Gas sender seal is leaking gas. Looks like I hosed up the install in the fall. Ordering a new one and doing that over this coming week.

I was talking to my brother-in-law a while back about his MJ. He's the original owner of a 1990 MJ pioneer. Somebody rear-ended him in 1991 and the dealer provided a Fey bumper (or a damn good match for one) as a replacement. Thought that was interesting.

I had the NSG370 in my 2008 and it had issues, same trans in the 2013 and no problems at all. Luck of the draw I guess. On the 3013 they added a hill start assist feature and gave the ability to turn that off, which I did. Only difference I can think of.

I had a 2008 JKU Sahara with the 3.8L geared at 3.73, and concur on all points, plus I'd add that I hated the trans popping out of gear randomly when starting off from a stop. Five years ago, I traded it in for a 2013 JKU Rubicon with the 3.6L geared at 4.10, and the difference is night and day. To my pleasant surprise, Jeep fixed every annoyance I had with the JK by the time 2013 rolled around. They even upgraded things I didn't realize bothered me (ref added notch in tailgate retainer to keep it open).

March 2018: Pennsylvania Personalized Plate Arrived Silver Star spent the winter parked. Over this past weekend I put the seat back in and put the MJ into service in the yard moving downed trees from the recent noreasters. Then this came today courtesy of the commonwealth...

Yes.

Yes, because upon logging out you become a guest, who doesn't have the same history as the account you just logged out of. Thanks for reverting the changes, Pete. As noted by other members, guest access is a necessity from a usability standpoint, and it's required to maintain search engine visibility. I'm glad the experiment was short-term, because if this had gotten picked up by Google, there would have been detrimental long-term effects from a search engine / traffic perspective. Believe it or not, even though guest traffic looks high, it's mostly accurate. Software like this forum uses routinely doesn't log traffic from known bots, as doing so would give an inflated/pointless representation of user traffic. The only bots that would show as guests are unknown (not listed yet) or malicious in nature (trolling a target site for exploits). So I hope that clears that up.

BMP files generally are viewable on the web, but the forum software doesn't appear to be equipped to handle them in the same fashion as JPEGs and GIFs. Complicating matters is that you're trying to pull them from facebook, which uses a permissions structure and image references that would make that very difficult for the forum software to achieve what you want (ie: not worth it). So, you may have luck doing this with some JPEGs.

The new 4WD offroad adventures catalog/mag features a really cool Comando body on JK drivetrain project.

Read this. It has all the info you need.

I swapped turbines onto my 91 and have a set of four of these rims taking up space with new 235 radials on them if anybody is interested.

Very excited to see progress on this.

I have a set I can sell you for $80 shipped from York, PA to you. PM me if interested.

Thank you for the report. I've noticed this too, and it's annoying. I've just adjusted the forum settings so that by default these types of notifications are not sent/presented.

I'm in the middle of this myself. Same thing happened. It routes under the carpet and seat, so be prepared to remove those, then through the back of the cab in the middle.

I did alot of research before buying my first welder. Dirty Comanche hits all the same points I'd mention. Except the welder choice. A decent Hobart, Lincoln or Miller 110V 135-140 amp Mig welder is all you need for your Jeep. You won't touch the power on a 220V model when doing anything on the MJ. Eastwood makes a very good Lincoln clone. Stay away from Harbor Freight and choose to use gas instead of flux wire unless you've got to weld outdoors in wind. Plan on spending $500 on the machine, $200 on gas and welding wire and another $200 on safety equipment including a fire extinguisher. Toss in more cash for clamps and brushes and a welding cart. A 4.5" angle grinder with cutoff wheels will get the rot out quickly. You don't need torches but they're nice to have. You've got to practice on other stuff first. Then start with your frame. Save the floorpans until later, they require thin wire and way more finesse.

"Cloud" is basically a generic term referencing the Internet. When we use a term like "Cloud Storage" we are talking about storing something in an Internet-accessible location. Any type of data, any location that's Internet-accessible. Think photos on an image hosting service, your personal documents on Google Drive, your desktop computer backup being sent to a service like Carbonite, your phone data and it's contacts being sent to Samsung/Apple, etc. It's not like you're sending your stuff into the atmosphere for anybody to grab. Concerning security, would be easier for an individual to steal your data from your personal computer, or from a service provider? The service provider would have your data backed up in multiple locations, in multiple formats protected multiple firewalls managed by teams of people who live and breath data protection. The security for your home network is probably managed by a box provided to you by your cable company, and hopefully has the right security options set. The cloud is secure, and any part of it that has a problem ends up on the six o'clock news. Concerning backing up your desktop computer, look into Carbonite. I have used them for years. I think there's a yearly subscription of $60 or $70. You install Carbonite software on your desktop, and when it first runs it does a full backup to their cloud servers. Then it intermittently sends just changes. Bandwidth consumption after the first huge backup is next to nothing as it only sends changes up. If you ever lose a file, you can grab it. If you change a file and want a copy of it before the change, you can grab it. If your computer blows up and you need to load all your files on a new one, you can do that. Or, you can restore a corrupted drive. Whatever. You turn it on and forget about it until you need it, if you ever need it.

I believe what Windows is doing is creating a ghost image of your hard drive and saving that to the external drive. Or it's creating a proprietary image it can use in a restore process. Either way, it will be a point-in-time backup file which contains everything on the source source drive as of the backup time. Jeep Driver is point on, though. Consider the cloud as a viable option. Nothing he said was wrong or off base at all. Devices today are quite disposable, and the need for data sharing between them is increasing. On the cloud your data is backed up by mission critical redundant systems run by experts. Backing up to redundant drives is what we had to do a decade or more ago because a cloud wasn't available.
