My ZR6000 is in the shop for warrantee repair to replace the track drive shaft. This mechanical problem got me thinking about website forums and human behavior. If one searches on the TY and HC forum for spinning bearing on drive shaft (my issue) you get the impression this problem is very prevalent. I find this curious because there is no mention of this on the this forum. Responding to this perceived issue there exists a Driveshaft Saver product that expands the shaft to reduce the clearance between the shaft and bearing. It is sold to folks who want to be proactive to prevent potential failure. Now, after my driveshaft failure, I find myself wanting to buy this product. Is this just a emotionally based reaction? What say you?
