November 4, 200619 yr The most interesting threads seem to be Subie all wheel drive discussions. Here's a question-observation. I put my 93 Legacy AWD automatic on 4 jackstands and ran it in low to try to diagnose a wheel noise. [turned out to be a rubbing e-brake pad] I noticed all wheels turning at slightly different speeds, the right rear turning the fastest. [with the rubbing pad] I could stop any wheel with my hand and the others kept turning, of course. Ideally, should all wheels turn at the same rate under no load conditions like this?---perhaps varying resistance like brake or wheel bearing drag would influence this. Comments??? Thanks.
November 4, 200619 yr They won't all turn at the same speed jacked up like that unless you have locking differentials all the way around. If you just have open diffs then it isn't going to happen like that.
November 4, 200619 yr turning at slightly different speeds "differential" is derived from "difference" seems logical. http://www.howstuffworks.com is sweet, might want to plug around on there about AWD systems and more specifically to this, differentials.
