I have been having issues with my front end since I bought it and I can not seem to fix the issue. I have a 1998 e320 wagon with 160k+ on it, I have replaced all of the ball joints, the upper control arms, front shocks, as well as the sway bar bushings which were completely shot. The problem that I am having is that when going down the road I can feel the car pull hard with the worn in grooves on the road, it can pull both right and left. I took it to a local indie shop and he could not find anything. He said everything was tight. I found some hydraulic fluid in the boot of the rack, but have not lost any fluid since I found it. I am stumped as to what could be causing this issue, I am sure I am simply overlooking the obvious. Any help would be appreciated.
