Upgrade Rear Drive Shaft or carry spare?
For some background, I'm heading to Moab in two weeks for a week of hitting the best trails (Fins n Things, Hellís Revenge, Top of the World, Elephant Hill, Poison Spider/Golden Spike/ Gold Bar Rim, Steel Bender, etc.).
I'm getting my FJ ready and have started to pile up my "spare parts", such as CV axle, inner/outer tie rods, fluids, etc. and it got me thinking, what about the rear drive shaft?
I have a full set of RCI steel skids, but the drive shaft is exposed. One hit from a rock could put it out (obviously I won't be aiming to hit a rock with my drive shaft). This leads me to question whether I should:
A) Upgrade the rear drive shaft before going
B) Carry a spare OEM drive shaft
C) Say F it and not worry about it
I called around and found a local driveline shop that said they'd build me a custom 3" drive shaft with reinforced tubing for $375 (that's balanced, too). I can get the OEM for this price as well. Unsure of how to go on this, just don't want to be left with FWD only on the trails, especially since I'm the only Toyota in a group of Jeep's that are all built and on 35's/37's.
