Good looking truck. Congratulations on getting MJOTM

My nine year old is watching me scroll through your updates and says the fireplace is cool! I betcha I could climb it 😂.

Now that the carrier is set up, I can take care of the spindle bearings that fell apart. Here is what I started with -> All the roller bearings fell out of both sides. First step was to pull out the bearings-> As soon as that was done I packed the bearings with grease. Putting in the new bearings-> Used an aluminum bearing installation tooll but I know many other things would work -> Once it was flush, I used an impact socket the same size of the bearing to knock it in a little deeper into the spindle. TBC

That interior is mint

I have to go with the majority and say topper.

Spectacular pictures . Congratulations on MJOTM!

I ran into the same problem with my Cherokee. It would break down all the time and I had no back up car. It eventually got everything new, but by that time I was over it and wanted my reliable MJ back. I will have the Scrambler as a weekend toy. I don’t plan on any hard wheeling though. Until the CJ8 is up and running I can’t risk breaking down.

😁 I can't imagine a roll over! Glad you weren’t hurt or it stopped you from continuing to wheel. Looks like a lot of fun though.

Now that I have everything cleaned up and all the bearings and seals pulled - it’s time to start rebuilding. I now press on the inner pinion bearing and slinger on the new pinion -> Before pressing the new gear onto the new carrier I brake cleaned all the holes in the ring gear and ring gear bolts. Now on the press to seat the ring gear on. Very important to add red locktite to the bolts before torquing them to 60 foot pounds -> Now ready for the set up process-> The old carrier has shims behind the carrier bearings for proper backlash. The bearings need to be removed to get them out. They need to be kept together (left and right). This just gives you a starting point for the setup and not going at it from scratch. We have a special bearing puller for this, but on occasion they break when removing even with using this. We just use a Dremel to cut the bearings off if that happens -> The bearings off and the shims out (I use bailing wire to keep the right side separated -> We use slip fit bearings for setup. They will be taken off and on a lot during the set up, so we don’t want to damage the flight bearings during initial set up. After a bit of +/- shims we get an acceptable pattern -> We also have a slip fit race (bearing cup) to help getting the pinion depth correct. Now it’s on to setting up pinion preload. As I said earlier, this axle does not use a crush sleeve. It uses pinion preload shims to get the correct (15 inch pounds we set ours at) preload. After a slow process (we try not to use new shim kits because they are $$$) using unused shims until we get that magic number. When we are ready for the final pinion set you first need to drive in the inner flight bearing cup. Make sure all the shims behind the race do not fall out when doing this. Because of this inner baffle -> the pinion shims need to be put in before the bearing and pinion seal are installed. I use a tiny bit of grease to keep the shims together-> Then I place the shim pack inside on the baffle-> Pop the outer pinion bearing in and the oil slinger on top-> and install the pinion seal * don’t forget to oil the seal* -> TBC

Thank you. Your video made me wince when I thought he was going over 😳 . Had it as a daily driver until I found my Comanche

Yeah, it would’ve needed more than a bearing overhaul for sure. It didn’t stress me out knowing I was replacing everything but the caps on this. It does seem like a lot of work, but you get in a flow and you cruise right through the jobs. Thank you.

Rounded up everything I need to set up the axle -> Dana 30 open carrier Motive Gear 3.73 ratio R&P Pinion nut - 30185 Pinion washer - use the old one Pinion seal - 44895 Crush sleeve - none (pinion pre-load shims) * I forgot to remind you that all the bearings need to be oiled before being used* Outer pinion bearing set - 02820/02872 Inner pinion bearing set - HM88619/HM88649 Carrier bearing sets - LM501314/LM501349 Inner axle seals - 11899 Going to need - Hub bearings and seals # Spindle bearings # TBC - Rich

Alrighty - it’s rebuild time. I first needed to get the axle disassembled. Took off everything holding the axle themselves in. Reminder, You can’t remove the carrier with the axles in (don’t ask 😁)-> Find a spot to lay out the parts while making sure they were separated left from right. During disassembly the spindle bearings fell apart -> I will have to get these ordered along with all the needed bearings. Now on to pulling out the carrier. The caps need to go back the way they came off (left and right sides). The caps usually need to be marked to tell which side they match up to. I use a punch and put one stamp for right and two for the left. This being a Dana axle, the axle caps come from the factory punched with a letter. This axle used the letter T. One stamp was upright and the other on its side. Used my crow bar on the ring gear bolts to free the carrier once both caps are off -> And here is the carrier - not looking good, but not using it anyways -> Now it’s time to pull out the pinion. Pretty nasty in there -> Instead of a crush sleeve to get the pinion preload set up, this axle uses pinion preload shims. Make sure to get all of them out, because they tend to stick to the outer pinion bearing or fall off inside the housing. You don’t know exactly how many of these shims are used, so don’t be too concerned if there are a few. -> You can see what they should look like above ^. The circular steel slinger needs to be used on the new pinion gear. Now over to the press and remove the bearing to get to it -> And it should look like this -> Now I use the race punch to knock out the outer and inner races. The inner pinion race has a baffle and pinion depth shims behind it that need to be reused -> Usually the baffle gets a bit damaged during removal but they can easily reshaped-> There are two inner axle seals that need to be removed too -> Just need to clean the housing up in the parts washer. It needs to be spotless inside. The smallest particles can damage the bearings, so this is an important step. Don’t forget about the axle tubes also -> I forgot to get a picture of the inside of the cleaned axle, but I’ll add that later. TBC

I will do that for sure. Atlanta is 4:49 minute from the new place so that wouldn’t be a trip I could make every week like now

That is horrible. Sorry to hear that.

I don’t know what I’m gonna do when I head upstate? I have 3 really good junk yards within driving distance from me. Any idea how far this is from Tallahassee?

The axle was a Lot heavier than I thought. I couldn’t load it on to the trailer by myself, so I’m amazed I got the axle over the leaf springs and out of the Jeep alone. I had to have a friend load it up with me last night. Got it to the shop this morning and three of us unloaded it from the trailer. We set it on a free stand and I prepared to take the diff cover off and drain out the fluid -> Get the cover off and I was not happy with what I saw-> The rust is everywhere , but I’ve seen worse. Now that the cover is off, I flipped it over to drain out the fluid. I would say if I was lucky I got a cup of “fluid” to drip out -> Not sure how I lost what should have been a couple quarts of conventional lube . The Jeep has been garage kept for over 20 years and I’ve never seen anything draining on the floor? The rust I get, but no lube has me shaking my head. Until I started working on axles, I never really considered that axles may need inspection too. Positive news is that I have a new carrier, gears and bearings going in. I will be inspecting everything else that may need to be replaced while I’m in there. TBC -Rich

It’s a no go on the lunch box locker. I would have to buy the whole locker. I am running out of time to get this together before the move next month. I am just going with the open carrier and new gears. I took this Jeep to Tellico with stock gears and nothing else and I had no problem with anything we tackled. I don’t plan using it for anything more than Florida trails - I will be fine. I managed to get the axle out on my own this evening -> Picking the trailer up tomorrow after work and then bringing the axle in Thursday. I should have it all set up no later than Monday night.

Well this did not go as planned. Got the carrier unpacked and the locker ready to install only to find that the two internal spacers are missing Calling about getting the parts in the morning. Hopefully they will work work with me on getting those pieces

Kick a$$ MJ. Congrats on MJOTM

😆

He is mine - looks horrible but I got fed up with trying to get it to work

Just got the gear in for the Scrambler. Now I have the Motive 3.73 gears, the correct gear break carrier and the lunch box locker ready to go in. Pulling the bearings when I get the axle into the shop -> I will pull all the bearings when I go to set up the axle hopefully next week

Oh no. This is very sad news. My condolences to his family.
