mopower......you could be very right........it's been along time since I used surge. But once this guy showed me the new pin....I tried it and it stopped the clunking in my situation

:D :D :D :D

I have a triple axle with Ausco electric over hydraulic discs.
You can stop on a dime and they are fully adjustable from inside the truck. No clunking when taking off either which really used to drive me crazy.:mad: :mad:

Anybody have a link to the Ausco product? I checked out their web site and couldn't find it.
