Default Driving on beach/sand

Being a novice 4x4'er are there any problems/things one should do prior to driving a Challenger on sand/beaches (not directly in any salt water/spray). Reading the manual it seems Mitsubishi dont cover damage/failures caused by sand but there is usually sand in most gravel/mud anyway. Have studied the underneath of the Challenger and it seems extremely well sealed everywhere and a good hose off underneath afterwoods would that be all it needs? Anyone have failures of seals/bearings caused by sand or are all modern 4x4's protected from this?
Thanks

Drop your tyre pressure to about 20psi and turn off your traction control.

Then enjoy.

Put her in low range as well. Don't worry about sand. Just enjoy.

Lucky, on the Paj you can only turn off stability control via the ESC/ASC button

Wouldnt contantly be using 4LL

How fast you going? Mainly say use 4LL to give the autos an easy run

Chris,

On my Auto PB Challenger I find the following works for me in sand.

Firm Sand; 4wd High Locked and 18psi to 22psi in the tyres, switch "OFF" the ASC. The Traction Control can not be switched "OFF" and the ASC will automatically switch "ON" if you turn the engine off and restart it, so it is easy to forget to keep turning it off. You want the ASC "OFF" as the ASC ECU/Yaw Sensor will sense the sideways movement can you get when driving through sand and intervene by cutting power and applying the brakes to one or more wheels, this will lead to getting bogged.

Soft Deep Sand; 4wd Low Locked and 14psi to 16psi in the tyres. ASC is automatically switched "OFF" and stays off but the "ASC OFF" light does not come "ON". I use low range 2nd, 3rd & 4th in the semi manual gear selection 99% of the time when driving off road as I don't need to go fast, it gives better control and I am already in low range if the going gets tough. Auto will start moving in low 2nd (it is the same gear ratio as high 1st) but will not change into 5th in low range.

The standard underbody plates are very thin and soft so they easily mould around everything they are meant to protect, I reshaped mine in deep soft sand in the first hour of sand driving so an aftermarket set of underbody plates including an auto trans plate is a wise investment.

Have fun in the sand and remember to stay out of the water, it is a car not a boat!

cheers, old Jack.

If you're new to driving off road it would be worthwhile doing a course, either through a commercial operator or a 4WD club.

One thing that can't be stressed enough is to not panic!

A few times on sand I'll begin to bog down but the paj will just very slowly creep forward, all times I've done this the car has slowly driven out of trouble.

One common mistake that I'm sure we are all guilty of at some point is when you lose all momentum, STOP! your brain says "gun it" but this generally doesn't work.

Had this yesterday, got bogged in some very soft sand at a local 'playground' consisting of rock, sand, gravel and a shitload of rubbish! When I lost momentum, I quickly stopped accelerating (belly only just started touching the sand), took a deep breath, climbed out and let pressures down to 18psi, gently reversed and slowly accelerated forward, got out in one shot!

Previously I just gunned it and both times needed snatching.

I have self-taught everything however its taken a lot longer than that of what a course could teach.

Cheers

Marc

I'm a noob too, but I've found that 20psi in the soft rutted tracks is ok and let it torque it's way through in 4H 2nd gear rather than lots of revs in 4H 1st. Too easy to spin and dig in when you're doing lots of revs in first gear. In 2nd it tends to "float" better.
