Off-road repair items for 3rd gens?

What are some common failures off-road for the 3rd gens? I recently took an off-road repair class (it was awesome, we got a ton of hands on training and we even got to practice extracting their company truck using a big log ratched to the rear control arm to skid an axle without a wheel on it) and am trying to set up a repair kit for when I go off-road. I know that the tie rod is one common failure in the IFS on the 3rd gen tacos, so tie tod splints and spare tie rod ends is a good add. The CV axles can also snap in certain conditions, so a spare CV isn't a terrible thing to have if you have the payload for it. Other than those, what are some common failure points in the 3rd gen tacos that I might want to bring spares for? (other than universal spares like spare tire valve stems, fuses, wiring and butt connectors, etc)

 

In 5 years with my 2020 OR, I haven’t broken anything except front and rear plastic bumpers, taillight, the plastic lettering highlights on my TRD skid, and the whole right side of the body.

Oh and I lost the rubber molding on the roof to a car wash.

 

• Spare wheel cylinder and a 10mm line wrench to change it.
• Drum brake hardware kit
• Fuel and coolant hoses of various diameters that you can cut to length, and hose clamps of various sizes.
• Spare brake hoses (one for front, one for rear).
• Spare ABS wheel speed cable for one corner, can be used to repair broken wires at other corners.
• Supplies for electrical repairs - crimp butt connectors and ring connectors, small spools of 14ga and 18ga wire, heat shrink, spare fuses, wire stripper/crimper.
• Spare air filter if you don't have a snorkel.

Plus common road trip repair items:

• Fan belt and tools to change it.
• Set of wiper blades.
• Headlight bulb if halogen.

 

Everyone has a different comfort level. Some prepare for nothing and some bring everything. Part of it depends on how hard you wheel. Going with others you can split the chore of repair items.

Here is an extreme example of all the tools required for a worst case scenario.

Not specifically 3rd gen, but tools/parts I've had to replace/use for me or buddies on trail that fit in a truck:

General Wheeling:
Tire plug kit
wheel lugs and nuts x 6
Serpentine belt
Hose clamps (hose and resi mount sizes)

For harder wheeling trips:
CV axle

 

Other failures seen with Tacomas in my off-road club:

Three cases of bent/broken rear driveshaft.

Disconnected rear shock bushing eyelet.

Front diff mount torn out from frame.

Sheared front diff intermediate shaft.

Broken power steering pressure line.

Cracked rim.

 

I carry fuel, front wheel bearing, CV shaft (two or three if I'm wheeling hard), UBJ, inner and outer tie rod ends, BJ press, impact, pulley puller, jump box, spare lug nuts for both the spacers and the wheels, torque wrench, breaker bar and pipe, hi-lift, BFH, MAP gas torch. I don't care too much about electrical repairs trailside...I can usually limp it to a parts house if needed.

 

Toilet paper and wipes.
Don't leave home without 'em....

Water, flashlight(s), blanket, first-aid kit, battery bank for recharging the phone.

 

If you don't want to carry a full spare cv, sacrifice a cheap aftermarket cv (or a broken one if you can find one) just for the outer spline shaft. That way if you break a cv (either side) you can simply pull the axle out of the tri-lobe cup on the diff side and swap the stub shaft in on the hub side, saving the bearing unit while you get home.

Outer tie rods, spare boots and hose clamps are s good idea, tie rod splints are good for a broken tie rod, but more likely just to bend one.

Split Cv boot kit, grease and hose clamps.

Fuses.

Flare kit and a length of hard line with some unions for the brakes. Extra unions, because you might, like me, forget to put one side of the union on before you flare the cut line (lol).

Extra fluids, coolant, diff gear oil, engine oil etc.

Something to pstch the fuel tank if you puncture it.

Air compressor and a plug kit.
