Subject: [Tigers] Steering Wheel Vibration

  Recently, while performing maintenance on the wheels of a trailer, it became apparent that a wheel hub had a heavy spot. Having made incremental improvements to the smooth running of my Tiger over the years, and having often wondered whether the hubs could be a source of vibration, that trailer hub made me determined to finally answer the question.


A front hub was removed from the Tiger and cleaned, hoping to use its own wheel bearings (clean and dry) to perform the test. That setup wasn't sensitive enough so I adapted a wheel balancer shaft with cones addressing the bearings on each side of the hub and riding on high quality, dry bearings. The result was that each of my hubs was out of balance on the order of 1/2 ounce. A hole was drilled on the heavy side near the outer perimeter of the backing plate and enlarged until the hub balanced. The final hole on each hub was 7/16".


As the hubs are relatively heavy and much smaller in diameter than tires and wheels, I expected that in the end, this would prove to be an exercise to eliminate the hubs as a source of vibration. On the contrary, the very first test drive revealed a much improved ride with noticeably reduced vibration, mostly in the 60+ mph range where an improvement was most appreciated.


If you would like to steady the steering wheel of your Tiger and improve its ride quality, experience with my car suggests that balancing the front hubs is well worth the effort.
