Torque multipliers are readily available tools. Just bring money. For the
most part 1/2-inch drive, (Standard) tools are meant for work up to 150 ft.
lbs. There are some 1/2" drive torque wrenches that go up to 250 ft. lbs.
but it is work to use them at that range with the short handles. For this
job you really need 3/4" stuff and even then a breaker bar sometimes is not
enough. Using cheater pipes and stuff is an abuse of tools and carries a
risk of things breaking with the falling off and stuff flying that goes with
it.
For the individual doing casual work a 2HP compressor with a 20 gallon tank
will run any tool you need even if briefly. Even a 3/4 impact wrench. If you
have alloy wheels the striker wrench won't work with the wheels on. Having a
set of impact wrenches and a 3/8" drive air wrench (non-impact) will take
hours off of so many repairs.

I've occasionally wondered why one of our Van'Fam' Fabricators
(Alistair or ?) hasn't come up with a
Torque Multiplier Tool, Or an A Mod to the Old one for the Bug, that will
work on a Vanagon ~
