This bulletin provides instruction to update the hydraulic steering system by adding an external pressure relief valve. Field reports of failed steering pump seals led to testing that determined internal recirculation of hot oil was the cause of the seal failures.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
