Q: ball joints

Vibration felt through the steering wheel at high speeds is often due to tire imbalance/tire defects although worn suspension components can be a contributing factor. If ball joints have failed early, there are only a handful of possible explanations for early failure: 1) the ball joints were not in fact replaced; 2) they were replaced but failed due to lack of lubrication; 3) the rubber boot on the ball joint tore and the lubricant leaked out; 4) the replacement part was sub-standard (e.g., not a Toyota OEM part) or defective; or 5) the replacement part was not the correct part for your application. In your circumstance, the best thing to do is obtain a diagnostic that will pinpoint the reasons for the vehicle vibration. Once you have that pinpoint diagnostic in hand, only the relevant parts (or balancing services) will be replaced, helping to keep your repair bill to the minimum possible. I wouldn’t replace anything further until you have some assurance that the work will permanently resolve the vibration issue.
