Terry,
AW S#!T
I just helped Scott Nutter replace his steering gear box and we couldn't get the Pittman arm nut to loosen even with a 2 foot
breaker bar so I handed him my Harbor Freight 3/4" impact wrench (puts out 1000 ft lb) and he hit the trigger and it was off in a
heartbeat. He noted he didn't even feel the impact wrench torque at all. It is a very heavy tool so its mass is probably why it
didn't torque.
The good news is that along with the box we replaced the lower steering shaft as well.
Regards,
Rob M.

Northern tool has the large wrenches for a decent price. If you get a combination (open-end and box)wrench you can increase your
leverage with another large combo wrench as long as you can get the box end on the pitman nut. It will also help your steering wheel
lock and your resultant torque if you have someone hold the steering wheel while you twist that nut.
I do not recommend using the impact anywhere on the steering shaft when the system is connected to the steering wheel and those
CV-type joints and especially the slip joints. They(steering shaft assemblies and steering gears)will withstand all the torque you
can put on them by hand, but the hammering of the impact can get absorbed by those joints and internal parts which can be
detrimental to their continued functionality.
