97 Impreza outback -- flat tire -- no fuse.

[Josh Assing]

about 1.5 miles from home, the car got a flat, which; some nice folks
helped change the tire & the wife was on her way.. When she got home, I asked if
she put the fuse in.. I got the dreaded "what fuse?" response.

Question: How much damage was done? it's not making any weird noises or
anything...

Thanks

Oh yea -- it was the right rear tire.

I'd have to say it's no big deal. 1.5 miles is what, 3 minutes of the car
"thinking" there's a slight amount of slip. It's comparable to riding a
clutch slightly for 1/4 mile, since the clutch packs are in a viscous fluid.
I wouldn't worry about it.

BTW, you do have the 4EAT automatic transmission, right? Otherwise there's
no fuse anyway...

Well; she said it felt weird -- like it "pulled the car" to the left when she
got on the gas.... that made me think it had "broken out" of AWD.

Yes; there is a fuse, near the passenger side front strut tower.

Thanks

so at worse, it's just the clutches that are shot -- not any physical damage?

At worst, it's the clutch packs. It probably took some life out of them, but
no big deal for the distances you're talking about.

Getting on the gas with an "uneven" tire will make the car pull - I recently
experienced the misfortune of bending a rim on my STi, and with the spare,
the car would pull right under acceleration.

On the automatics, the center diff will perceive the rear to be going slower
than the front - as though the front were slipping. The clutch packs will
engage to move power to the rear and "force" the front and rear to spin at
the same rate.. I'm not sure about the 4EAT specifically, but I'll bet the
clutch pack solenoids only engage when you're accelerating or under power,
which further reduces the potential for damage unless she was blasting
around town from stop lights on the way home

Here's a follow up Q -- if we run it in "FWD" mode -- will gas millage be
improved?

It seems to me that if it shuts off the "AWD" mode; that it'd do better -- but
it might be that I'm not seeing the "big picture"


thanks

Still hauling the same weight and the extra differential is still turning
so I doubt that mileage improvement will be measured from0.0 to 0.1 mpg

Thanks -- I didn't think so; but "one never knows"
