| Description of the problem | I began experiencing a stiffness in my power steering on 12-15-08. I checked the power steering fluid level and it appeared to be low. I added a few ounces. Two days of driving later and there was no change. I took the van to the toyota dealership today, 12-18-08, and they identified the problem as corrosion to the flex joint of the intermediate shaft of the power steering rack and pinion. They did tell me that the situation could degrade to the point where power steering could fail. Cost of repair was quoted as $500 plus $70 for related/required front-end alignment. The root cause was said to likely be water entering the seal of the joint, causing rust to form on/around the bearings. Other reports of road salt being the cause, seem to suggest that under-carriage cleaning would, in fact, prevent the corrosion. This dealers position is that the high-pressure spraying of the under-carriage was, itself, causing the corrosion to begin. |
