07 E350 4Matic REAR DIFFERENTIAL HEADACHE!!!

Hello Mercedes fans! I am new to this site but I have recently had bad news for my E class and could use any possible suggestions. As stated in the topic I have a 2007 Mercedes E350 4Matic sedan with 75,000 miles on it. It has been babied all of it's life but recently i have been hearing loud humming noises from the rear which i thought was from the new tires the car has had recently put on it. As the noises got worse my concerns grew. Today i took it to the dealership in Paramus NJ and they threw it up on the lift and determined there was a bad bearing in the rear diff. I didn't know that Mercedes had a worse warranty than Hyundai, being that Mercedes has a 5 year 100,000 mile warranty and Hyundai has a 10 year 100,000 mile warranty. They told me the repairs would cost a projected $5,900.I am extremely disappointed as my warranty has expired about 9 months ago. I thought Mercedes was a high end car so could someone please tell me why the differential would go so early as i said this car has been babied and driven by my 54 year old mother all it's life! Is there anything i can do to get Mercedes to cover the repair?! Any advice or other similar stories would be greatly appreciated!

Bad bearings in diffs do happen but not often.
Were the fluids ever changed in the rear diff?
It will cost you about $3700 from parts.com for a new one, the dealer probably quoted you a rebuilt diff.
I don't know how many hours are allocated to a rear diff swap, my guess is 5 to 8 .
If you do confirm that the rear diff is bad, I suggest you find a good indy, buy the part from parts.com and save yourself about $1000.

Reman from MB is part # 211350981488. List is $2125 (Internet pricing is odd with a core of $570, but parts.com is selling it for $2040.)
I need to check a dealer that wholesales and if the core charge knocks the price down to the mid $1500 price range. That would make the shipping worth dealing with parts.com.
If not then if your dealer has no other damage and the drive axles are intact then I just do not see how there can be almost $4000 in labor if they use a reman diff.

Please get a breakdown of parts and labor so we can help you get the best price.

Just a note the part listed by Roadking for $3720 is the same part 2113509814, just an OEM MB factory rebuild with the same warranty as the one that is $3720.
by add 88 to the end of the number designates it as a rebuild part that MB is selling.
So I really hope the dealer would go that route as it is saving $1600.

I did a rough calculation of parts and labor and if just the bearing is the only damage then the price is high. So they may be trying to sell you a new one. The most book time for labor I could find was 15.2 hours.

i had my rear diff replaced a month ago at the dealer on my 06 E500 4matic. parts from the invoice :luckly covere under CPO warranty.

211-350-23-62-88 axle housing
170-990-00-10 bolt and washer
120-142-00-72 hexagon nut
126-997-00-41 ring general
211-350-23-62-88 core return
001-989-33-03-12 transmission

doesnt say price on the invoice just WARRANTY. But guessing $3400-3500?? I've been trying to get as much fixed before my warranty runs out in May 2013

My local indie replaced my failing pinion bearing for less than $1000 last year. Find a shop that has the jigs to rebuild your diff and save a lot of coin...
