My understanding is that parts for the BA 10/5 are rare, and expensive. Despite my preference for manual transmissions, if you do off-roading with oversize tires (even 31s), you're really better off with the AW4.

If you heard air coming from the valve cover, your air line was not connected to the oil pressure sender, it was connected to something/somewhere else.

^^^ What is this photo supposed to be showing? Did you swap the threaded adapter from the old engine?

What year is your MJ? The BA 10/5 would be correct for an 87 or 88. Is your truck stock? My '87 MJ and my '88 XJ both have the original BA 10/5 in them, and they shift fine. The XJ (and the tranny) has 287,000+ miles on them. How do you drive? The BA 10/5 doesn't like to be treated like a drag race transmission. If you like to slam shifts, you'll probably kill it quickly. If you drive it like the [light duty] truck transmission it is, and allow the syncronizers time to line up and do their thing between gears, the tranny will likely last forever. 2nd gear, in particular, is "notchy." Mine don't like to go into 2nd when cold. On cold winter days, in fact, I run up a bit faster in first than I usually do, and skip 2nd until things have warmed up a bit. Also, I always double clutch downshifts -- in all gears. That's just habit. I was taught to double clutch by my grandfather, and my first several card didn't have synchromesh on all gears so double clutching was mandatory. It helps even if the tranny has synchros.

As Pete wrote, what's needed to remove a lift depends entirely on what was done to create the lift. In the case of my '88 MJ Chief, when I bought it there was a 4" TrailMaster lift on it. The lift consisted of taller front coils, front control arm drop brackets, rear add-a-leaves, and longer shocks. To correct the axle offset, I had added an adjustable track bar. Putting it back to stock involved installing stock front coils, removing the drop brackets, removing the rear AALs, and installing a set of OEM replacement shocks. Then I discovered that the adjustable track bar was an interference fit and was rubbing against the diff cover at stock height, so I had to get an OEM replacement track bar. FWIW, most of us regard "stock height" as measured from the axles to the body/chassis, so even on 31s my truck was returned to "stock" height, even though the tires raised the whole enchilada about an inch farther away from the ground.

If you want a front D44, get the axle out of a TJ Wrangler Rubicon. It's a D44 differential mated to the tubes and outers of a late-model XJ. Bolt in swap.

Well, that's just wonderful. The Verizon web site clearly shows that both the J3 3rd Generation and the J7 2nd Generation do NOT have a removable battery. But the chat agent (or bot) on the web site says "No worries, the battery is removable." I just read through 182 pages of the downloaded user manual for the J7, and it doesn't mention either the battery, or the internal sensors. The cell phone industry has obviously entered the commodity stage. It's no longer considered important to tell users anything useful. 'Take what we give you, peon, be happy with it and STFU."

Good to know. Thanks. [Edit to add] As a result of this comment, I just went to the Verizon Wireless web site. The prices I was given yesterday were the same as they were a year ago -- $7/month for the J3 and $10/month for the J7. On the web site, the prices are $0/month for the J3 and $5/month for the J7. But ... apparently not the most current versions suggested by DirtyComanche.

Speaking of GPS, I had an amusing interaction this afternoon. I'm still cruising along with my Samsung Galaxy S3 cell phone, which even I admit is getting a bit long in the tooth. But it still works. A year ago I tried upgrading to a newer Samsung through Verizon -- and I sent it back within 48 hours. I HATED it. My old Galaxy S3 defaults to a restful, black background with white text for most screens. The new one was black on white, which is both more difficult to read, and more tiring on the eyes. The only option Verizon could suggest was in the accessibility options, where there's a feature to reverse the display. That got me white on black -- but it also inverted the colors for all the screen icons. So I thought I'd try again. It's now a year later, but the two Samsung phones Verizon offers that are within my budget range are still the Galaxy J3 and Galaxy J7. Both and entry-level smart phones. Aside from the screen color issue, neither includes a built-in compass or gyroscope. In the year since my aborted upgrade, I've been playing with some compass and aircraft/sailboat navigation apps, and I've learned that compass apps do strange things when installed on a device that doesn't have a built-in compass. The apps (most of the ones I've tried, anyway) can use GPS to generate a compass heading as long as you're moving, but as soon as you stop the heading defaults to North (0 degrees). That's obviously not useful when hiking if you want to stop on top of a hill and take a sight to a landmark in the distance. Or sight along a known heading and pick a landmark on which to align. I tried to explain that to the Verizon sales drone, and he just couldn't get it. His "solution" was to just download a compass app. "You don't need a compass in the phone."

Yes, a 4-cylinder with the AX-4 4-speed transmission would have a 3.55 rear axle. The good news is that all 4.0L automatics came with 3.55 (or 3.54) axles, so you can pick up a front axle out of any 4.0L XJ or MJ with an automatic transmission. The best choices will be late 90s, because they'll have larger/stronger u-joints -- but they will also have the composite front rotors that are prone to self destructing in the rust belt areas. The 2000 and 2001 XJ front axles use different (and better) rotors, but they're low pinion. That's not an issue on pavement with stock size tires, but the low pinion axle is slight weaker so not the preferred choice if you'll want to run big tires off-road.

I just pinned this thread to keep it near the top of the index. We can un-pin it when Don gets home. Tell Donald to behave himself and follow the rehab regimen. If not, we'll have to send a recently-retired U.S. Marine NCO over to straighten him out. Yes, Donald will know who I'm talking about.

You don't have to change to auto. The AX-5 is physically the same as the AX-4, and there should be 4-banger XJs around with the 5-speed tranny. Jeep made the XJ with the 4-banger right up through 1999. Look for one with the external clutch slave cylinder.

I would guess it's not a big issue if both diffs are open. Since everything I own (except one '88 MJ that I haven't started working on yet) has a limited slip, I would expect issues if flat towing.

Yes. I'm after the warranty when I go with the Auto Zone "Gold" products.

Mean Green? Big $$$. Personally, I'd go with one from Auto Zone or Advanced with a lifetime warranty.

By "not a true neutral," I am referring to the fact that the earlier year 231 and 242 (and I guess the 207, as well) transfer cases have a neutral position that disengages the transfer case from the transmission, but leaves the front and rear outputs locked. The result is that, if flat towed, the engine doesn't turn but the front and rear axles are connected and act like they're in 4WD. https://www.jeepforum.com/forum/f12/true-neutral-plate-1076065/ https://www.youtube.com/watch?v=hHM2DzjLOvg

The resistor pack also has a thermal fuse in it. I've replaced multiples of them, all because the thermal fuse blew. In my case, the problem was always mice building a nest in the air box. The nest material gets wadded and packed around the resistors and fuse, causing the fuse to overheat and do what fuses are supposed to do. One of these days I'll try my hand at soldering in a replacement fuse.

Does the fan run if the control is set to the highest speed position? That position bypasses the resistors. If the fan runs on high speed, the problem is the resistor. If it doesn't run on high speed, the problem is somewhere else. I've never had to troubleshoot the control switch, so I can't help with that.

Did I understand that the truck was running before you did the tune-up? What year is the truck? The ballast resistor wasn't used in 1987 -- it was introduced in the 1988 model run. Also, please clarify the opening post. "Turning over" means the starter is turning the engine, but the engine is not running and won't start. "Firing" means it coughs and sputters while cranking (turning over), but the engine won't actually start. If the engine actually starts and runs for a few seconds, that's yet another condition. We need to know exactly what it's doing before we can be of much help.

The click could be the fuel pump relay, but there's a long circuit between the relay and the pump. When you first turn the key on, you should hear the fuel pump running. If not, you need to check the entire circuit. Cruiser's suggestion on the ballast resistor is a good starting point. Have you checked the fuel pressure in the injector rail?

??? What did you figure out? For the older XJs and MJs, flat towing meant removing the driveshafts because the transfer case doesn't have a true neutral. I don't remember when Jeep finally fixed that, but I think it was after the demise of the MJ.

The packet included a DD-215. I don't even have to request it. Feels weird being awarded a bunch of medals I never even heard of. Who'd a thunk it?

But I should have been. I just discovered that I'm some kind of flippin' war hero or something. Back story: Some time back, I read about somebody having been awarded an Army Good Conduct medal, and after a bit of research I realized that I probably should have received a GCM ... but I didn't. So I wrote to some address I found on-line, and got a reply telling me to submit my inquiry to some other office. So I submitted my inquiry there, and then forgot about it. It felt like a classic bait-and-switch, with each office telling me to talk to someone else. I thought that was going to be the end of it. Fast forward to this evening. I retrieved the mail from the mailbox, and found a thick envelope from the U.S. Army Human Resources Command, Awards and Decorations Branch. It includes a bunch of papers, a DD Form 215 (which corrects my DD 214), and a cover letter. According to the Army, I should have received (and now will receive) the following: Army Commendation Medal Army Good Conduct Medal Vietnam Service Medal with two Bronze service Stars Meritorious Unit Commendation Sharpshooter Badge with Rifle and Carbine Bars Republic of Vietnam Gallantry Cross Unit Citation with Palm Device Republic of Vietnam Civil Actions Honor Medal Unit Citation, First Class All I was expecting was confirmation that I earned a Good Conduct Medal. Instead, I found that I'm due five medals I knew nothing about. (I already received the Army Commendation Medal, but if they want to send me another one, I won't refuse.) It's a good thing I don't have a Class A uniform any more. I'd have to start working out to wear all that salad on my jacket.

Whatever you do, the interior should be one color. I think gray seats with a blue interior would look ... odd. My preference would be to go with an all-gray interior, but it's probably a lot easier to get the seats redone to match everything else.
