So I started this today! Got the second battery mounted. Freed up quite a bit of room to mount the actuator for the front locker and to mount the auxiliary fuse box I posted about previously. Was very easy to mount... Just used a battery tray from a junkyard jeep.

I looked up your son's name and I don't know him or your nephew! But your son does appear to work on the flightline. So we do work in the same vicinity.

Front LED lights, rear LED lights, on board air, auxiliary cooling fans, and some other stuff. It gives me a really good platform to build off of long term. 5 relay circuits and 5 fused circuits
-
So I got my fuse box from a member over at cherokeeforum It is great!!! Super high quality and very impressed with how complete the kit is!
-
Also took my dog for his first ride in the back of the Jeep this weekend after we got the new speedo gear in! He did extremely well!! He's about a 7 month old, miniature Australian Shepherd. His name is Scout! He loved riding back there!
-
Just a little update, got the speedo gear installed this weekend, actually, my wife installed it for me! I just showed her what needed done and she did it! So now when I'm doing 50MPH the speedo actually says 50MPH and not 80 or so.. Lol
-
Thanks for the information guys! Got the gear installed yesterday! It works perfectly! I really appreciate the info on here, prolly would have not clocked it right had I not seen this thread!

We should go wheeling sometime! I'm stationed at McConnell as well! -
I am getting ready to install my gear in when it comes, any tricks or tips to make sure it's clocked right so I don't eat mine up?

Where in kansas are you located?? I'm in the wichita area! -
So, did final assembly today and ran into a couple of snags. Primarily installing the C-Clips. In order to install the C-Clips you have to remove a snap ring, conical thrust washer, spider gear, and center pin inside the OX locker. ... Not really sure if OX just didn't design their C8.25 locker for 4.88 gears or what. My guess is they designed it for 4.55 at Max. So any numerically higher gear (wich is thicker) won't work.. Due to the pin not being able to come out, it hits the ring gear. So with a little bit of creativity and persuasion I got the C-Clips installed. Will be a huge pain to do a trail repair if I ever break an axle shaft though... That's the downside. This is what was happening when trying to remove the center pin. But after getting that figured out I got it final installed and took it for a test drive! Final Specs: Pinion Preload - 12 inch pounds Pinion Nut Torque - 255 Foot Pounds I didn't write down my final shim thicknesses. Was able to torque the pinion nut to 255 Foot Pounds exactly because I used a crush washer eliminator kit, wich used a spacer and shims to set the Preload. Similar to the D30 up front.. Man!!! Such a drastic difference!! I have so much low end torque now it's not even funny!! My interstate driving is pretty much shot with these 33's though. But, the best upgrade has to be in how this jeep handles with an open differential compared to the Spartan lockers. No more popping in turns or it pulling to one side or the other. My front locker was completely trashed, the rear one looks practically brand new though! So with these 4.88 gears, at 50 miles an hour I'm at 2k RPM with my AX-15. But I'm cool with that, I plan on 35's or 36's later on. Wich will correct it to some degree.. My speedometer is very off now it said I was doing about 72mph when my GPS said 50mph! Lol so I need to address that... I put it it 4WD Low and with the Chevy HD planitary that's in the transfer I COULD NOT stall it!! I pressed the brakes to the floor and pulled the E-Brake and it barely slowed down the truck when I was in 1st gear just idling. No throttle input at all and I just couldn't get it to stall. This has been a hell of an experience learning how to do a gear install and a locker on top of that. But I'm very happy I did it myself. I feel like iv grown quite a bit as a mechanic. Wouldn't have been possible if it wasent for all of the knowledge on all of these forums! Next step is to mount and wire the electric actuators for the lockers.

So turns out... My C8.25 was a 27 spline.. Not really sure where the confusion happened. Previous owner and the Ad when I bought it said 29 spline... Needless to say, it wasent worth keeping the 27 splines. That.. And I have a 29 spline OX locker. So that problem was remedied today! Got some 29 spline axles from the junkyard! The Size difference is pretty significant! Definitely a lot sturdier axle! When I do my disk brake conversion I'll get some chromoly axles and keep these as spares... Also got the pattern set on the rear axle! Tomorrow is final assembly!

So you bedlined the floor, Dynamatted over the top of the bedliner, and threw down frost king, and then carpet? Any issues with the dynamat sticking to the bedliner? No sir, this stuff really sticks. Just make sure it is rolled and pressed hard enough to get rid of the diamond pattern in the material. This stuff made such a drastic difference inside the cab it's not even funny. And I still don't have my headliner installed. But frost king? I don't believe I mentioned frost king, what is that?
-
So I finally got the front done yesterday! Locker and gears are final installed and I just have to mount and wire the actuator for the cable. And hopefully will get the rear done this week!
-
And this is for comparisons sake. The last pattern where we agreed more depth and the new one where I added ten thou depth today. New on left, old on right
-
-
Whatcha think? This is after adding 10 thou to the pinion depth and 5 thou to the carrier shims. My backlash is .006, so it's right on the edge..
-
How much does pinion preload matter? What are the reprocutions if it's less than 10 inch pounds? Obviously, if it's tight it increases friction and therefore heat.
-
My current specs are: Pinion Nut - 250 ft lbs Pinion Preload - 15 in lbs RG Backlash - .008 How much should the preload increase with the carrier installed? about 5 - 10 in lbs? That is what i have read on a couple different places. To increase this load, simply increase the carrier preload by adding more shims right? Okay! That makes since about the factory shimming there. I planned on using Lucas gear oil.
-
Thanks!:] What specs do you have for a Dana 30? I have 12-15 in lbs on the pinion. Well, I have a setup race and have been removing it and adjusting the shims under the raise because that is where I believed it needed to be adjusted. I guess with a setup pinion bearing you would shim at the head of the pinion? Everything I have read online they shim under the race to adjust the pinion depth. I had my carrier shims in such a way that it was a snug fit, took some umpf to get it in by hand. When added 5 thou more it was darn near impossible to get it in, had to really hammer it in. Should that be my goal? I don't have any any shims less than 5 thou. Thanks for the info! I really appreciate it
-
Yep.. Was gonna add 5 thou. I am shimming under the race, are there advantages or disadvantages to one method or the other?
-
Have made some progress... Still don't like the pattern though... I need to adjust the pinion depth some more and I think I'll be okay. Been such a harsh wind here it's been hard to get much done and with the rain too. Sucks working out of the back of a box truck and in a parking lot! Lol I'm pretty excited to see what these 4.88 gears will do!! Big jump from 3.55 If anybody has some advice for these gears I am all ears! This is my first time doing a gear swap.
-
If you don't mind me asking, what's your cost gonna be to have them installed?

Added! Wichita KS

Also been getting some work done on the over head console!
