First the specs on my rig:
3.6l 6-speed Sport-S
Stock 3.45 gears (SUCK)
Rear: D44 w/LSD
Front: D30
Current tires: 280/70/17
Planned tires: 35’s (most likely 315/70/17, maybe true 35x12.5 if I change wheels) — Note: Won’t go larger then 35’s as the jeep won’t fit in the garage.
Suspension: Currently running Rubicon take-offs. Planning on Mopar 2” later down the road
Usage: Mild city driving. 500 mile round trip to in-laws happens a few times a year. Local off-roading is former iron ore mines so lots of rocks. I avoid mud when possible. I also get out trail riding whenever possible. I enjoy the flexy stuff.
Question:
These 3.45 suck big time. They need to go and the wife is in agreement. There’s a local person selling a front D44 from a JL Rubicon. No brakes, no knuckles, but does have the stock 4.10 gears w/e-lockers.
1. Do I swap the front D30 for the D44 then regear the rear to 4.10?
2. Do I skip going D44 route and just regear to 4.56? (Original plan until a friend started talking about axle swaps)
3. If I go d44 would I have any issues knowing the front axle would be slightly wider then my rear? I’m assuming not outside of needing rubi tie rod. I’m thinking any issues with alignment, etc.
4. If I go d44 anyone know if the D30 knuckles will fit on the D44? I’m assuming so. It’s a bummer this axle for sale locally doesn’t have the rubi brakes as I know they are a lot better.
5. If I stick with the D30 would you recommend trusses and c gussets ?
Local person is asking $2k for that axle which seems a bit high, but I’ll let others chime in on that. Seems like on the board $2k/axle seems a bit on par but typically comes with brakes.
Any other advice people have or have experienced would be greatly appreciated. Photo for example of local trails.
Thanks in advance.
