[Off Road Driving] Bog Holes
When you encounter a BOG HOLE:-
always try to drive around it, as the depth of water and mud is unknown, however, if there is no alternative, check the various depths with a purpose built 'wading' stick (on which you have marked out feet or centimeter graduations) or alternately use a shovel, tree branch etc.
If you are not on your own, observe the vehicle in front of you and take your own corrective action as needed.
ENTERING THE BOG HOLE - Remember, every situation is different.
* Select an appropriate gear, usually 2nd or 3rd low range, and this depends on the depth of the bog hole. Engage Diff Lock and Lockers (if fitted).
* Depending on the situaton, it's sometimes a good idea to switch on your windscreen wipers just before entering the bog hole.
* Steady power and momentum must not be lost. If you begin to get stuck, swing the steering wheel from side to side.
* If the wheels spin, ease off the throttle.
* If you get stuck, try reversing immediately and stay in you own tyre ruts.
RECOVERY FROM A BOG HOLE
* When bogged, it is possible to lift the rear end (HiLift Jack, Air Bag Jack etc), and slew the vehicle sideways. This can result in a better position for grip. If forward movement looks unlikely, reverse out.
* If completely bogged with no help immediately available, lift the vehicle body and place under the bogged wheels, any dry coarse matter such as rocks, tree branches, and if you are carrying them, recovery mats. If you are carrying an Airbag Jack, place it under the vehicle near to the bogged wheels. Inflate it. This usually provides sufficient lift to allow some wheels to gain better traction. Leave it under the vehicle as you reverse as it will roll with the vehicle, however, if you have placed rocks or branches under the tyres, make sure these don't puncture the 'Airbag jack.'
* If a Snatch Recovery is required, remember to fasten your seat belt.
WHEN YOUR OUT OF THE BOG HOLE
* Wash off any heavily caked mud from inside of the wheel rims. Failure to do this could cause bad wheels balance problems. Check there is no mud on or in the radiator cooling fins, as this will cause the vehicle to quickly overheat. Clean out also any mud caked onto the driveshaft as it could cause them to get out of balance.
* If you happen to get water into the ECU computer, strip it down as much as possible and dry with compressed air (if carried) and spray with WD40 or a similar water repellant spray.
