Eureka,we have found it. Thanks - you are both right on. The broken off corner is still there, between the propane tank and right rear tires. During our BC blizzard, that whole wheel well was packed full of ice, engulfing the propane tank. I'm hoping all that ice caused a wire to be pulled resulting in our ABS light to come on. I've driven the Alaska highway 21 times now, but you never know what weather you're going to hit, and that storm from Ft. St John north past Muncho Lake was a doozy (Apr 23-25). Road was closed for a day and a half while we waited in Ft. Nelson.
New to us '04 Journey 36 with 330 Cat will be towing a '14 Sonic 1.4 liter turbo 6 spd. '05 Dodge 3500 Cummins, '09 Subaru Outback, plus a few other toys that help us get around in Alaska.
