sorry just read your thread- are you still having issues?? We found a place in Tenn that fixes them very reasonably- ASI company Rogerville Tenn ph# 866 983 6688
good afternoon- you might contact ASI co. in Rogersville, Tenn ph# 1 866 9836688 we used them to repair our ABC on our 2001.don't know if they could help but worth a try & very inexpensive.
we are having a brake job done on our 2011 & we asked the mechanic to check the nuts.sure enough- one was almost off.............going to install 2 new ones!!
