Tranny cross member all painted up and ready to install. Got all the tabs built and tacked in. Taking a break. I will post finished pics in a little bit, resting my neck for a few minutes. It is a pain laying on your back and welding.
All finished up...well almost. Still have to figure out how to get my front ds to occupy the same space as the tranny mount. Will have to determine if I am going to clock the t- case or not before I can finalize that. Has anyone clocked theirs? Thoughts?

Got all the accessories back on the engine tonight and started running wires. There are a lot of wires on that Grand Cherokee harness. Nothing picture worthy today. More wiring tomorrow, should get into some more complicated stuff. Oh goody.
I have been researching and preparing for my wiring for about two weeks. Tonight I started tracing and labeling wires. This is going to take some time. I will try to post as much technical information as possible during this stage of the build. I am learning and will do what I can to relay the things I learn so others can use it later. As always, any advice is welcome.
Been busy with other stuff this week and did not get much done. It warmed up in PA today so I thought I would take advantage and finish painting the frame and the exhaust manifolds. Hopefully will be able to get back after the wiring some tomorrow.'
Don't tell the wife I had my manifolds in the oven. I know some of you guys understand.
shot of the manifold on the engine and the newly painted frame. I love the texture of the Duplicolor Bed Armor for the frame.
I pulled the diff cover on the front D44 because it was leaking after I had the jack under it. Yes, the PO of the axles did not use a proper gasket. There was a fair amount of waterand a lot of sludge in there so I am glad I did it. Good news is that I found out that there is a Detroit True Trac up front and 4.10 gears. I would rather have at least 5.46, but with the V8 and auto tranny they should work pretty good. Anyone know what gear oil I should with the True Trac.
OK...so I have been researching my gears and according to the stampings I have a 4.56 ratio. The PG stamp is for Precision Gear. According to their web site the part number for a Dana 44 with 4.56 ratio is 44D/456R. As you can see from the pic, those numbers are stamped on the ring gear. When I count the teeth on my ring gear I get 41 on the ring gear, not 50. So...either I can't count or the numbers stamped on the ring gear are wrong or I am confused. Does anyone have any input here?
I don't care much how it does on the highway. I am running an auto with overdrive so that might help anywho. I currently have the brand new 35's, but am trying to decide if I want to go bigger. I can fit 40's. Thanks for the info.
Still somewhat confused on my gears. I recounted the teeth and was not completely wrong. I marked each tooth with a sharpie this time so I was absolutely sure. 41 teeth on the ring gear and 9 on the pinion, which equals 4.56. Seems all cut and dry...right? Well, not so much. The gears are clearly marked with the precision gear logo. According to their web site the 4.56 gears for a D44 have 50-11 teeth and the 4.56 gears for the D30 have 41-9. Can a D30 Gear set be installed in a D44? What other explanation could there be?
So I measured the ring gear diameter and it measure right around 8.5", or the best I could tell while still in the axle. So they are definately D44 gears. Not sure why the tooth count does not match the precision gear web site, but I am moving on and just be happy that I found a LSD and 4.56 gears in my axles. Not what I was expecting when buying axles off of a scrapped vehicle.
Did some more wiring tonight. Got a bunch of un-needed wires out of there. All ABS stuff is gone and the head light stuff. I will be running the lights off of the YJ harness. Made a lot of progress tonight. Hopefully some time in the near future we can hear this beast roar.
AWESOME BUILD!! Interesting with the gears/markings. I may have missed something but did you check the rear to make sure its not 4.10 like you thought the front was? That would suck to get it on the trail and have it hand grenade on you cause of mismatched gears.
Have not pulled the rear third member yet but I will. There is too much play in the pinion so it will definitely need to be addressed. Both axles came out of the same vehicle so you would think they would have matching gears, but you never know. I know tha rear has a mechanical locker of some kind so I need to identify exactly what I have back there too. Not a priority yet. I'm trying to stay focused on one task at a time. I only pulled the front diff cover because it was leaking on my floor.
Started sorting wires on the Yj side tonight and got the PCM mounted to the fire wall. Also figured out where I am mounting the PDC. I am going to mount it to the battery tray. I know, All of this is useless without pics. I will get some up tomorrow.
Pics as promised. I have read mixed opinions about mounting the PCM on the fire wall above the Distributor, but it just makes sense there. I think the PDC works well on the battery tray. I will weld or maybe bolt it permanently in place once all of the wiring is buttoned up.
Finally got back at the Jeep tonight. I think the Grand Cherokee side of the wiring was easier because there are better schematics. I can't find a really good schematic that identifies the circuits and ties them into the bulkhead pin out. I have three red wires from the bulkhead labeled battery. I am not sure where to tie them into the GC wiring. Any insight would be appreciated.
