carry a 2' to 3' of chain(small link) and a few 3" or 4" bolts that has threads all the way up and will fit through the links of the chain. Have 2 nuts for said bolts as well as different width washers. Loop the chain around whatever you are trying to keep in place put the bolt through the chain as close together as possible. use the washers and nut(s) to tighten the chain. It will take the slack out acting kinda like a turnicate. If there is enough chain left you can use it to wrap around something else and tighten it again. I used this a few times on an Isuzu Trooper II to hold the leafsprings in place. It should work to hold a control arm in place as long as you loop it in at least two different directions.

Also cardboard is good to make an emergency gasket.

You can use starting fluid and a flame to set a bead while the tire is still on the rig(just dont use too much!)

JB weld and a pop can work really well to fix a hole in an oil or transmission pan. Cut the pop can in sheets and layer it for best results. Start with a small circle and progressively get larger. Seal with JB every "layer". Another Isuzu Tip.

If the battery is dead, drive a stick so you can drift start it i HATE autos for this reason! Dam slip-0-matics!

I'll think of some more in a little bit.(Im burnt-out)

You can't push start a TJ with a dead battery, no matter what transmission it has...

When you have a dying or dead battery in a TJ, a whole bunch of stuff starts acting crazy. You really need 12V or close to it.

I think he means too dead to start over the engine but not dead enough to power the coil. Like the ticking you get from the starter.

I've done it.......a couple of times.

An Ajax and water paste on a tors bit helps not to strip the stubborn bolts while taking them out.

Nope.
No voltage to the PCM also means no fuel control...

I've drift started many vehicles with fuel injection. When the batteries were so low that they would only click-click the starter and not turn over the alt.
