Hello everyone. I've been driving my car around Seattle and I'm starting to notice something odd with my car when I'm on a hill. I have a 2005 Forester 5MT and I've noticed that when I'm on a steep slope of a hill, my back rear wheels seem to slip before gaining traction. I didn't give this too much of a concern in the beginning, but recently I'm starting to notice it happening even in a rather regular sloped hill or even on a flat surface when I'm trying to merge onto traffic. Does anyone have an explanation for this? I've read around and perhaps my alignment could be the culprit? Or maybe my AWD system not functioning correctly? Any insight would be very helpful. Thank you!

Welcome to the forum!

Sounds like the system is not functioning as it should; there should be bias to the front wheels not the rear. Alignment should not affect traction. Is the tire tread depth equal on all 4 wheels?

do you have matched tires?

are they the same tread depth.. can measure approximately with a penny if you dont have a depth gauge or caliper.


Edit: just saw you have a MT.

That should be a simple vicious coupling controlling the power....

you will probably have to investigate farther.. the actual vicious coupling is not serviceable.

Could be just the tires. I have rented a car before, every time and steep on the gas in wet road the tires will slip before getting traction even the tires are new.
