Re: (ET) Skipping steering

     It depends on HOW rounded, and WHERE they are rounded . If the missing 
material  is at the very tips of the teeth, it is quite possible that 
judicious modification can result in another lifetime of use. In my case, I 
went the 'extra mile' and also installed a roller bearing to support the 
sector shaft. A hole was drilled through the support to accept a Zerk®, and 
a corresponding hole was ground into the bearing case to allow the grease 
in. The more looseness and lost motion you can eliminate, the longer the 
pinion and sector gears will last, even if worn.
  The next fly in the ointment is the sector gear working loose on the 
sector shaft. Short of trying to weld the gear to the shaft, I have yet to 
come up with a lasting fix for that issue.
