Shhhhh: Dont let carma know, I have been very lucky and to date I have only un seated a coil on the trail.
Of course I did spend a week in Moab with 3wd and a leaking transmission seal
Oh and I ran over my sunglasses, does that count?
Dont get me wrong I have done some damage to the truck, mostly just needing maintenece when returning home, its not for lack of trying! I believe it is because I built my BII to take it, "overbuilt" if you will, at least for the drivetrain and I have only been running a locker and 33's for a year now, so that helps.
I attribute my trucks reliability to me knowing its limitations and being a ana* mother ###*#$ when it comes to maintenence
Here are the spares I carry on longer trips:
starter (automatic)
spindle, bearings, spindle nuts
D35 TTB inner and outer axle shaft assembly
Spare hub(s)
Full size inflated spare tire
lug nuts
transsmission cooler lines
spare 5 prong relay (fits ford dist box and ARB relay)
vacuum hose
Front axle U joint
front driveshaft u joint
rear driveshaft u joint
gloves
duct tape
zip ties
electrical wire
bailing wire
come-a-long
fully charged jumper box
on boar air
ATF
Coolant/water
oil
gear oil
bearing grease
Not to mantion the tools, tie straps, gloves, jack, first aid kit, etc...
THINGS I SHOULD HAVE AND NEED TO GET:
Hi lift jack
tire plug kit
flares
shovel
Most of this junk believe it or not fits into a medium sized rubbermaid with a locking lid. I have started to carry my tools in a bag, to compact them because I got sick of the noisy tool box. So far being prepared has helped a few trucks get off the trail......
