Recently replaced a failed outer tie rod end with a $17.99, lifetime warranty, non-grease fitting, MasterPro tie rod end from O'Reilly. I had four tie rod ends from O'Reilly's to choose from. Prices started at $17.99 for the MasterPro part I bought, up to $71.99 for a Rare Parts tie rod end. Both the cheapest tie rod and the most expensive had lifetime warranties. Seems like a no-brainer to go with the cheapest since it still carried the lifetime warranty and is only a 10 minute job should it fail prematurely. O'Reilly tends to stand by the parts they sell, so I'm not overly concerned regarding quality. Anyone else experience such drastic prices in parts from the same retailer? If so, did you find quality was directly proportional to cost?
