AWD in the snow

1994 LSi
in the snow only the front tires spin when i give it lots of juice. Is that normal or should all spin?

The front wheels are a bit biased. They should only spin for a second, while the car is trying to figure out what wheels are supposed to be not spinning and whatnot. This seems normal. Unless, of course, your front wheels are spinning constantly and the rear wheels dont seem to move at all...then your in trouble

Mine does this sometimes.. usually I'll have to floor it for the rear wheels to "kick in"
Gotta love our 70/30 power bias

That is not normal, and you're wrong about the torque split. The split can be anywhere from 90/10 to (I believe) 50/50. It's not commonly the latter, but can be.

If your front wheels slip significantly before the rear 'kicks in,' I suspect your transfer clutch is badly worn. My wife had a 1990 Legacy that did the same thing. None of our other AWD automatic Subarus, when they were working correctly, did that.

What He said!
But check your TPS and make sure it is correctly adjusted to 0.50 volts at the white wire at the TPS.

I was under the understanding it was a 60/40 split.

I wish i could get my car out in the snow. It iced once this winter and my car ended up coated in 1/4 to 1/2 inch of ice with no ice on the roads! Now the freaking leaves are starting to pop so i guess winter is over. Now i have to drive this damn car yet another year just to try it out in the snow! Damn.

The car can go to 50/50 when working properly.
If you want snow, just drive north.

and I'm ready for spring by december 22nd!

After I replaced the transfer clutch on my Teal one years ago, I never noticed any front wheels spun at all. Even when I floored it on the thick snow, the power light just came on, and, 4 wheels were spinning instantly. While my yellow is still in the process of making her better...

PS: I have noticed my yellow 4.44 tends to slide on the snow when you're trying to accelerate...? I read one member saying the LGT 2.5 likes to do this. Is it because of the more torque transferred to the rear?

Hey, cool username dude
Make sure your engine fusebox does not have the FWD fuse in the slot...it should be empty..thus engaging AWD

Then you were wrong. Torque split on the SVX is variable, again from 90(front)/10(rear) to 50/50.

I have heard of people spending $900, but I think it should be well under $500. The parts are not terribly expensive and, if you know what you're doing, it's not that time-consuming of a task.

The dealer will likely try to talk you into replacing the transfer solenoid while they're in there. I'd let 'em. The labor is identical, so don't let them add any on for it. Swapping out that solenoid is a five-minute job once the thing's open.

oh, well then that's cool. But under normal conditions what is it? (normal meaning not on a hill or curve and at constant speed)

It was until I saw it. Now he can try it again and keep it a little more family friendly. This will not be allowed.

As I understand it, while traveling at a constant speed the car only diverts 10% of the torque to the rear wheels. As soon as any number of variables change, though, the TCU starts putting pressure on the transfer clutch and diverting more pwoer to the rear. My point was that is should do this instantaneously without the front wheels slipping first. The 'RealTime 4WD' set up on the CR-V does work like that, though. I hate it, but find it funny that Honda's AWD works like Subaru's when it's broken.
