Driving on the freeway last night and the front end starts howling like an air raid siren. Turns out the front differential is toast after just 5300 miles! Anyone else had this problem on a GL?

WOW...sorry to hear that! ![bow](https://mbworld.org/forums/images/smilies/bowdown.gif)
mine only has about 3k miles on it so far and no problems, knock on wood!![Big Grin](https://mbworld.org/forums/images/smilies/biggrin.gif)
...I would be starting a war with MBUSA on that...I dont think that should happen on a brand new GL with only 5k miles!!![smash](https://mbworld.org/forums/images/smilies/smashfreak.gif)

Hmm seems odd. Have you changed wheels or anything? I haven't had any problems with both our 550's. I am sure your dealer will replace the diff under warranty. Do keep us up to date please as this is the first case I have heard of.

Yes, I needed snows for winter. Mounted 265/60 R18 Dunlop M3's on all new rims. Rotation is almost identical to the factory 21" set-up. The big tires would be sleds in the deep snow and ice.

Do you think it could be related? How many miles did you do on your new snow tire/wheel set up before differential went? I have been thinking of going 18" wheels with snow tires like you, but now am concerned....

It really can't be related as long as all four tires are the same size.
Good idea, however, to have the Mercedes dealer mount the wheels.

Less than 1,000 miles on the snows. I doubt it is related. The difference in rotations per mile is so slight, it is not enough to make a difference. And, yes, all 4 wheels are the same size.

The dealer found metal shavings in the differential fluid. Not sure what caused them, but they led to the noise issue. Maybe a flaw in a ring or pinion.
The service I got from MB was 5-star.
They overnighted a complete axle and replaced the entire assembly. I had the car back the next day. It drives great with no other problems. We're getting hammered with snow, and this truck is absolutely fantastic!

Apparently, it's easier to build a quality customer-oriented business from scratch than to convert one that isn't customer-oriented.

Is there a common issue here? Which diff is having the problem. I have a MY09 450 and seem to have a growing whining sound from the passenger front side. Let me know if that's the same place you had the problems, anyone who has had it.
BTW, the noise started a week before I put the 22s on so it didn't start the problem.
Thanks.
