- There are a few things I've used in the past, with varying degrees of
- success.
-
- 1) Jack up the vehicle and place material under the wheels, or push
- the vehicle off the jacks sideways/forward/backward. The idea here
- is to reposition the vehicle to free whatever portion of the frame
- is caught.
-
- 2) Play around with the brakes while attempting to drive out. If the
- emergency brakes can be used to isolate the spinning wheel, it
- will transfer power the to wheel with hopefully some traction.
- I've done this by using a rope attached to the emergency cable
- of one of the rear wheels and pulling on it while driving out.
-
- 3) If your going to pull on the vehicle, attach the a suspension
- member or the frame. One possibility here, assuming there are
- trees around, is to use a long cable between the vehicle and
- a tree. Then attach a garden variety come-along to another
- tree and the middle of the long cable, the come-along should
- be pulling perpendicular to the long cable. This will produce
- a large mechanical advantage in the pulling force. You may
- have to reset this a couple of times since you won't move
- the vehicle much each time. I've had good success with this
- appraoch with just two or three people instead of the comealong.
- They can rock the vehicle in time with a drivers application
- of power.
-
- 4) Oh yah, that prings up the single most overlooked procedure of
- all, mostly overlooked by non 4X4ers. If you have any traction
- at all, rock the vehicle by shifting between 1st and reverse.
- This either gets you out, or totaly stuck. My old scout II
- was good with this since reverse and 1st were in line with
- each other.
-
- One side note, I've been wondering if a fully independent ABS
- system would be usefull in such situations. If you hit your brake,
- the system should apply the brakes on the spinning wheels only and
- transfer some power to the wheels with traction.
