Is there any tricks or tips on why speedometer drives last such a short time? The one before last was in there for years then one day it failed, I replaced the gear end on the drive shaft and that one stripped within a few miles. Both were the brass type.
The rear hub is a fairly new genuine part and I can't see anything wrong with the drive gear. The cable and the speedometer both turn freely by hand.
Any ideas what's wrong? These drives ain't cheap so I want the next one to last more than a couple of miles!!
