Subaru Forester in snow, get two wheels off the ground

Impossible to get out from the snow trap without external help when two wheels hang in the air .
By the way this "2001 Subaru Forester S 2.5" model has LSD, but seems it does not work properly.

у меня друг продал такой форестер. Там что то в коробке случилось и распределения не было. Один мост только тащил. А в ролике машина стоит практически на ровном месте. Мой бы вызез и не чихнул да же. За машиной следить надо.

[qxbutch]

да, повесь форика диагонально - и не выедешь. Распределение между осей в момент на ролике 50/50 (крутится и передняя и задняя ось с одинаковым моментов), но проблема что нету (или не работает должным образом) задний межколесный дифференциал.

[qxbutch]

В результате весь момент ушел на переднее правое и заднее левое колесо.

Если бы была система , которая притормозила одно из висящих колес - то момент бы передался на стоящее колесо и выехал бы.

Старые форики не выезжают

S type forester doesnt have Limited Slip Rear Diff(LSD), basically you have open Diff, that's why your wheels spin.

I have 2003 forester xs, with Rear LSD, this will never happend

[qxbutch]

You are not right

2001 S Forester adds over L model:

limited slip rear differential (package not available on L model)

[akpch]

This is Forester X, it has no rear LSD, just regular differential. XS and XT, auto or manual has LSD on the back. My wife has XS, I was not able to get stuck in sand or snow.

[qxbutch]

You are right about X and XS Foresters, but...

This is Forester S 2001MY. So it has LSD according to specification.

Forester S 2001MY has LSD

Forester L 2001MY does not.

Seems the problem is that LSD does not help in such offroad situations when two wheels completely do not have contact with the ground.

apply brakes gently to trick the diffs

[Zachard]

So in situation like this you have 3 options:

1) Apply extra light breaking manually (along with throttle) to slow down the 100% free spining wheel so the other will get some torgue and start moving

2) VDC will do the same job (new models)

3) Install a rear LSD with locking ability (Viscous, clutch or with other locker mechanism - type diff)

[luder5555]

@qxbutch I don't know what type of LSD the Forester S uses, but I would guess a torsen type. In which case, when one wheel on that axles is completely unloaded, it acts like an open diff.

[Infamouslyminded]

LSD isnt going to help anyway if you have two wheels with no traction, a major amount of torque escapes through wheels with no traction and doesnt leave the other two with enough traction to push the car out, happened to me this winter in deep mud ruts and snow

[warfl4g]

so, when you're in this situation, your choice of actions are to... give it more gas? :| redneck solution

He;s singing the open diffy blues!

[Zachard]

TO ALL PEOPLE THAT WONDER WHATS WRONG:

Nothing is wrong with this AWD system. There is a difference between an LSD diff (like the rear) and an LSD with locking ability (like the center).

Most preferable rear LSD diff is a TORSEN type one (TORque SENsitive). These diffs are acting like open when 1 wheel is in air (free spining = 0 torgue).

[Slurfs]

AWD is NOT 4WD. However Subaru Forester is one of the more reliable and capable AWD's around even if it sucks in some situations like this. As another guy pointed out he should jerk the handbrake (mean to the center diff but will increase the chances of getting out of this mess).

[pastormikeb68]

In Amerika we call these guys IDIOT!!

[ujayyy]

@thenixter97 not necessarily, as we like it free-style =)

[R1Wagon]

PULL THE HAND BRAKE!! Or just apply slowly the brakes with the left foot

In situation like this it helps regain traction of the right wheel... but dont hold it too long ;)
