Thanks Mike

serial number of first failure was
A 232 R 01712 Y purchased in mid 2001. We have 5 other trucks all showing similar signs of wear with hours varying from 13000 - 23000, but mostly around 18000. The initial failure is in the truck doing most turning working in the warmest area of plant. Ambient varies from around 22 - 34 degrees C. The 23000hr truck travels mostly in straight lines.

thanks
