Yea I had a pretty good feeling thats what it was wrong. It has to be pressed exactly on the putter edge and can not touch the black ridged part or it will damage it. It's kind of like a sensor that spins with the wheel to tell the speed/abs sensor how fast that wheels is turning. If it is pressed wrong it can damage it and not spin on the wheel bearing which will give no reading to the sensor causing a failure to the abs Dsc 4x4 and brake module. They all work together. I had the same issue with mine and I found the info on alldata. The part should be no more the $100 (around $90) and about a hour and a half labor for the wheel bearing labor ( according to alldata): glad u fixed it. Alot smoother too now huh?
