AWD .. stuck?

antonRS · 02-10-2001, 12:19 AM

i was in an empty parking lot but the snow+ice surface was too high and my car was stucked (99RS 4eat). I tried rolling the car back and forth trying to push the car out... while doing this, i looked out at my front and rear wheel. The front is moving, BUT the back is - n o t -

is my RS a FF? emm.... ???

anyways, as I was rocking the car back n forth, it finally got out, however, the (ABS) light came on.

I recall that we discussed about the 90/10, and 50/50 power distribtution b/w stick & slush... but if my front tires lose traction, it *should* transfer power to the back right? Or is it because the snow+ice is so high that my car is lift up? ...

Pls help me out...

As people mentioned before, for AT, gear one is 50/50

Anytime youre stuck, put the shifter into 2nd gear. That on the autos, bypasses 1st, so its much easier to get out. Its in the owners manual. Also, don't worry about the ABS light, it will go away. Some snow/ice must of gotten stuck by the sensor on the rotor. It has happened to me before.... Dont worry

should've gone out and dig. your car was prolly "lifted" off the ground. Anyways glad u're ok.

Yes AWD works in reverse, too.

Trust me, I know.

antonRS · 02-10-2001, 02:29 PM

emm... thats what i thought too!

however, while i was stuck last nite, my friend was standing beside my car, and he said that all 4 wheels were moving when I am goin forward, but when going backward, only the front wheel is moving

even if my car is lift up by the snow - all 4 wheels loose traction, they will still spin right?

antonRS · 02-11-2001, 12:12 AM

thanks guys!... how about in reverse? AWD suppose to work in "R" too right?

Hello,

Unless you have modified your car so it has three locking diffs, all four tires will not spin under low traction conditions, open diffs lead to spinning and stationary tires.. Next time it happens, have your friend check the other side of the car, the passenger tire was probably spinning. In sever conditions while spinning tires fiersly, you will have essentially 2 wheels driven with open diffs (and the stock "locking" diff). Put a locking diff in the rear (as in the newer RS's and people wo have upgraded theirs) you get a worst case of three wheel drive.

Just a little clarification. On an AWD car with open front and rear differentials and a "locking" center differential, the car is really two wheel drive unless traction is equal on all four tires. One front wheel and one rear wheel will have most of the torque. On the 2000 model year RS the rear differential is limited slip (viscous coupling) so this car is actually three wheel drive unless the traction is equal on all four tires. If you install a limited slip front differential on a 2000 RS then the car will be true four wheel drive requardless of the traction difference between any tires. Open differentials send power to the path of least resistance.

I had this exact same problem on my '90 legacy (4eat). I was trying to get out of an icy parking spot in reverse, but only the fron wheels were spinning. I know this because I got out of the car and saw that the rear wheels were both dry while the fronts were wet from spinning in the ice. THis was both in forward and reverse (i tried all gears).

I checked the Tranny codes and found a 'Previous' problem with the 2 VSSs, but not 'Existing' problem. (if you know about the procedure for checking tranny codes you'll know what i mean). Do a search in the SVX forum and you'll find the method for checking this (although I don't know if it applies to Imprezas, it's easy enough to try out)

When I got stuck in the snow last weekend, and was high centered on a snow bank, all four wheels spun in 1, 2, and R gears.

Would have been nice if I was on the ground. 0WD was what I got...

Thanks guys for ur explainations! Do u guys agree that the AWD system on a 5-spd is better than an auto since it's 50/50?

and also, what are the differences b/w the 4EAT on a 99RS and on a WRX?

Thanks!

edit-> got the answer from the other post: 45/55
