My factory hubs lasted till 87000 before replacement. Took the time to go thru the whole drive train including new rear diff. Now I burn hubs in less the 10000 miles. After changing 3 sets of hubs in 2 1/2 years this is getting old. Tried Tenkin or what ever the cheap good part is. No good . Running raybestus now and the rears are getting loud again. Bought a new set of GM fronts and they made it 8000 miles. I am running hutchkis sport sways and fg2's on stock springs with standard aline in front an updaded alinement in the back. We're masters in the garage but this one has us stumped. Any smart input would be greatly appreciated. 04 CTS Sport
