Technical Storage Case Ford 9" used as a shipping container???

Sent it back and they said everything checks out OK. They did say the bearings showed excessive scoring with only 500 miles. They said it could be caused by Low Oil Level, Wrong Oil or Contaminated Housing. NOT....I bought oil they suggested, filled it to the bottom of the plug hole and wiped the housing clean with Brake Kleen before installation.

I think it was defective bearings installed or improperly installed. They offered to build me a new one or give me a full refund. I opted for a full refund. They put it through the same day.

It took 4 months from time of order to refund. Glad it's over!!!! I put my old 9" back in that only had a slight whine between 40-60mph. I can live with that after that terrible noisy new rebuild.
