So I got out on a trail for the first time today and was blown away with how well my S3 performed. It was a nice surprise. However, I pushed it a bit too hard on one rocky uphill section and now there is a nasty knock when the left front hub is locked. Unlocked and in two wheel drive it is just fine. What did I break?
Oh Jeff, you are such a downer! It could be that your FWH is not engaging all the way. Or what Jeff said Does it do it in 4x4 with the hubs unlocked? Hi and low? Then it's the axle issue, if only when the hub locked it's a FWH issue.
