rear whine

2006 F450 4x4 crew cab 201"
the rear has had a small whine since new but just thought it was normal
then at 45,000 miles dealer said sounds bad and probably pinion wearing out
they said $5000 to fix with no guarantee on noise

now that I have 122,000 miles it is terrible
hurts your ears at certain speeds but drives fine
Dealer said last week that it will need to be replaced soon
Anybody have thoughts or insite
I live Outside of Baltimore near Bel Air, MD
anybody know a shop that can fix this?

Re: rear whine

IMHO, most Ford dealers don't have a clue how to properly set up a rear end. My advice is to find a ring and pinion shop. A reputable one.

Now be forewarned, I believe some center sections aren't machined 100% correctly. My race car has been set up by two different shops three times and twice by me. None have been quite. Either bad luck of the draw, or something isn't right to begin with. However, that said, that's a Mustang with a substantial amount of the interior and insulation gone. Any noise will be audible. In order to hear a rear end noise on a truck it has to be pretty darn loud.

Re: rear whine

Sounds like ring and pinion to me too. But $5000 to fix it??? What the h***? Don't EVEN pay that kind of money to have a R&P replaced. Look around for a local driveline shop or even an off road shop. I re-geared my '06 when it was new to compensate for the tires. I don't remember exactly what I paid to have the front AND rear done but I think it was a little over $1000...MAYBE.

Re: rear whine

Another stealership fail. $5k for that job is just robbery. Are they replacing the entire axle with one made of platinum or gold?

Re: rear whine

this truck has had every problem a 6.0 can have as well as other stupid issues
bleeding hundred dollar bills by the handful and sitting in the shop for 34 major mechanical issues since new
I will have to look around town as at this point the truck has turned into a "HUGE" investment just to use for work

Thanks for the replies

Re: rear whine

34 major issues? Either you bought the worst 6.0 ever, or you are hell on a vehicle....

Re: rear whine

Most likely just the pinion bearings I would think. Check the dif for abnormal gear wear to verify.
