You can apply a small amount of braking with your left foot to take out some of the back-end bounce.
Poor man's ATRAC
Good idea though - I think a lot of that is traction flip flopping between left & right on the open diff, so the brake will stop the wheels spinning up so much...
That's probably why locking the rear diff helps immensely.

Not so much for atrac but to reduce the bounce in the backend.

I was out last night and we were on a heavily corrugated road at one point with lots of "woops" (?).... and I tried a bit of left-foot braking to keep the suspension loaded up. Seemed to help a bit.... others in the group tried it as well with similar results.

Re: Driving FJs in sand

I've gone as low as 12 psi in the Oregon dunes. You just have to watch out and not cut too sharp going too fast or you can roll a tire off the bead. Normally, I air down to 15-18 psi on the sand. To one of the points that @Iconic made, it's a must to turn off traction control. That'll bog you down before you even get started. Another item that a lot of people forget about is disabling your side curtain airbags. Use the "RCSA OFF" button. That way if you get a bit sideways, your side airbags won't blow on you. I've heard that ATRAC is good for when you do get stuck but I haven't tried it myself. And when you do get stuck, get off the gas immediately. I've helped dig someone out on an uphill dune before that just kept it floored until he was sitting on the frame. That takes forever.

When I start, I'm in Park, hold the traction control button a few seconds until it lights solid on the dash. RCSA OFF button, 4-HI on the transfer case and go for it. Sand is a blast.

My wife and I made a run down PINS last month...aired down to 20, kept momentum where it was loose sand and was smooth running in 4HI.

We did see a guy with a Camry down around mile marker 25 or 30, but I assumed he knew the lines and tide times to stay on the more packed sand.

Re: Driving FJs in sand

When driving along the beach, I haven't yet had to air down at all, tyre pressure up to 32 psi. For the Namib sand dunes we usually deflate down to 13 psi. That is with Cooper S/T Maxx tyres.
Traction and stability control off and gear selection 4x4 low 3 (auto box) for the dunes, 4x4 HI for the beach.

Re: Driving FJs in sand

I get a kick out of reading some of the posters early in this thread saying to the OP from Dubai, basically the universe of sand, that they know all there is to know about driving in sand, though their experience was in one very narrow window of humidity, temperature and type of sand.

I am eager to see what Amaclatch adds to the placeholders in the near future.

The most sand my FJ sees is on icy roads in the winter. There's always more to learn.


PS: Found a recent photo of @amaclach going for a drive. Definitely knows his stuff!

Good thread. Good insight.

I just had the opportunity to test out my crawl control at Oceana Dunes and it worked like a champ. I took about 1/4 of my air out and found that 4H was good for relatively flat terrain, but that 4L keeps you from getting bogged down on steeper climbs in the first place.

On one occasion , I was in 4L and purposely stopped short of cresting a steep dune and tried to start again. I began spinning and sinking to the frame. I engaged the crawl and slowly but surely, I crested and was free.

My lesson for the day is that MOMENTUM can be your friend in the deep sand dunes as long as you are aware of the shifting sand drop-offs, rollover dangers, and other drivers that await unseen over the next ridge. My other lesson was that crawl control is noisy, but amazing.
