I have a 1990 240 wagon with about 131,000 miles on it. I picked it up with about 122,000 and don't have a lot of maintenance information on it. I've got a list of things that should be done at the 100,000 mile mark if I want to keep the vehicle happy. One of the things that is listed is changing the rear shocks. Bentley makes it sound like the r&r is an easy procedure, but then Bentley makes everything sound easy. Anybody willing to give me the heads up on any tip, tricks or warnings regarding this procedure. I'm a determined amateur with tools and enough experience to make me really dangerous. Thanks.
