A couple weeks ago my truck had a whistle/belt slip noise around 1700 rpm, and my dealer said it was the S/C and they put one on order for me.
Well I took it in for repair and they called by 10:00 am, didn’t take them long. I went to go pick the truck up and the bill said that the S/C shown gear wear, so I asked to see it. Well the two roots/veins for lack of better terms had a shinny spot on each edge about an 1 ½ inches long, I’m sure that’s not normal but what do you guy’s think it was rubbing on, the case? Anyway I just barely heard the whistle/belt slip noise on the way into work this morning, so I’m not so sure it’s fixed.
On the good side of this I talked to the service manager and he said they turn a blind eye to mods but he doesn’t make decisions on blown motors and such. Ford makes those decisions.

 

so what do you guy's think about the shinny spots on the roots? Think it was rubbing on the case?

 

TTT

 

I had a few when I took my stock EATON off at 24,000. It had been spun with a 6lber most of the time and made no noise though....

 

I'm not so sure that's what was making my noise either...
