I have a 1990 240 DL wagon with a very frustrating problem. The car will "float" intermittently at any speed. I replaced ball joints, tie rod ends, struts and control arm bushings on both sides and didn't notice this problem prior to the front end work. Ihad a front end alignment in an attempt to correct the drifting. I was told by the alignment shop that it might the steer valve bypassing? I want to see if anyone else has experienced this symptom.
thanks
