Tire Re-Seat
You can re-seat a slipped tire bead by taking the weight of the vehicle off the tire and using an air compressor or air bottle to refill it. If the air pressure isn't enough to re-seat the bead you can wrap a ratchet strap around the circumference of the tire and continue to cinch it as air is added to the tire. Always wear safety glasses, gloves, and long sleeves, and keep hands and face away from the tire bead area. A loud pop will indicate that the tire is seated. You'll often hear more than one pop as the bead seats all the way around the wheel.
Channel The Power
Heavy-duty battery cables are a necessity when multiple electrical accessories are added to a vehicle. The light-duty factory battery cables can affect headlight brightness and even winch speed. If you have installed a winch or any other high load electric accessory, you should install heavy-duty battery cables to allow these accessories to function properly. A set of heavy-duty battery cables help channel power more effectively.
Poor Man's Welder
You can make an emergency welder using two vehicle batteries, two sets of jumper cables, and some welding rod. This will enable you to make small repairs to frame cracks, alternator brackets, spring or shocks mounts, etc., that may keep you from continuing your day on the trail. Two batteries can be attached in series and grounded to the vehicle or object being welded to create a stick welder. Make sure you carry a selection of welding rods to suit various metal thicknesses. To link the batteries, hook the positive terminal of one battery to the negative terminal of the other. The other positive terminal will be hooked to the battery cable holding the welding rod. The other negative terminal is hooked to the object being welded as a ground.
Stop Transmission Shift
The stock rubber mount can wear out pretty quickly when subjected to lots of water, mud, and heat. As this wears out, the transmission is left to react to power from the engine and leans rearward as you accelerate and leans forward when you stop. This puts extra stress on the driveshafts since the angle of the yoke shifts each time putting unnecessary strain on the driveshaft U-joints. To counteract such effects you can install a heavy-duty transmission mount that will keep the transmission more stable during acceleration and deceleration.
Tie Rod Sleeve
You can sleeve a bent tie rod using a Hi-Lift Jack handle. We never really thought this would work until we saw it done. This might not work if you have an extra-long Hi-Lift but the standard Hi-Lift handle is a perfect fit on the TJ, XJ, and YJ tie rod, and should work on a handful of others as well.
