2005 LGT Wagon with 185,000 miles. Rear alignment could not be done with the eccentric adjustment bolts frozen by rust.Substantial repair cost includes replacement of the rear arms and related parts at a price of just under $2000. Question: With this many miles and alignment records showing less than one degree out of spec during past alignments, I was told just watch tire wear and any squirrelly behavior before doing anything. Tires look good and I'll be swapping for winter tires (in the Fall) I have had for several years. Annual mileage about 6000 in the future. Any words of wisdom or projections of how long I can do without adjustments or scrapping the car? Engine, clutch and brakes solid. No body damage or accident history. Thanks all.
