Project Upsize: Axle Swap

I am starting the process of swapping the axles in my YJ.

I am swapping my open Dana 30 HP 3.07 front axle to another Dana 30 HP already geared at 4.10 plus I will be installing a Lock-Right.

I am swapping my open Dana 35 3.07 rear axle to an open Ford 8.8 geared at 4.10.

While I am addressing various aspects of my JY axles like brake rotors and pads I am also pricing my various drive shaft options. I will consolidate my final decision here, but for now I am tracking the various options here.

HP Dana 30 ($267):
Solid axle shafts from a TJ or XJ ($100)
Brake rotors ($27×2 = $54)
Check pads (good)
Rebuild calipers if necessary (good)
Extended brake lines ($85)
TRE flip
Sway bar bushings and disconnects
XJ drive shaft 1j4ff68s3xl590831 ($35)
Lock-Right locker w/ hardened pin ($296)
YAW39147-KIT Warn Vacuum disconnect block off ($40)

Ford 8.8 1fmyu24e0xub73816 w/ flange adapter ($214):
SYE ($175)
XJ drive shaft 1j4ff48s5yl174236 ($35+$93 = $128)
Replace brake pads ($27)
Check e-brake shoes (good)
Brake rotors ($31×2 = $62)
Hard brake lines ($8)
Extended brake line (Included above)
Weld Tubes ($25)
E-brake connection
Mounting kit ($118)
MORE Shock Mount Extensions ($103)

33″ Trailcutter MT ($661)

Drive Shaft Options

This will detail the various options I have for both the front and rear drive shafts during my axle swap. Hopefully this will control costs while allowing me the most reliable options.

All prices are Midwest prices.

Decided on the standard SYE kit and a modified front XJ drive shaft.
