Recently ford issued a TSB #18466 about rear axle whine on F150's. Ive got lots of whine and if anyone knows what this tsb says I would sure like to know.
thanks

 

I'm not sure about your TSB number, but there's been more than one TSB on that subject. They all say about the same thing, replace the ring and pinion. The latest message gives part numbers to kits that have the ring/pinion, bearings, seal, nut etc. for both the 8.8" and 9 3/4" rears.
