Y’all keep talking about getting a good used rear axle, but that’s total oxymoron!
Mine started making noise at about 50k miles. With that said they’re all actually bad, so finding a “good used one” is out of the question. You can buy rebuilt ones so that means parts to rebuild are available, at least to select vendors. I want the option to rebuild my own.

Have you changed yours with a brand new one or rebuilt one?

What would you recommend?

Hi
yes i have the same problem with a 2016 CLA 250 . the dealer has just been dismissive but admits there is an international problem with the CLA
has anyone heard about a recall or any information about Mercedes admitting in righting there is a problem ??

Hello Everyone, I have the same problem with my CLA, just 31000 miles on it. Have you replaced it with a used or rebuilt or brand new?

I would really appreciate any suggestions and the cost involved. I don’t want to pay $5,000 for a brand new one.

Sorry I don’t. My car was covered under extended warranty when the issue arose. It’s been running like new ever since it was fixed. Knock on wood.

Hello Traxem, I thought you said in a previous message that it costed you about $2500 plus labor for a reman?

 

[Clanaim]

Just a reman diff is already 2500 ... sure hope you can source a good condition used unit ... seen some on ebay from wreck yards
Do you see any wiring harnesses? If not then you should be ok
Whats the existing one doing now?

Thanks for the info, do you know how I can get a good reman or rebuilt one?

I posted my repair invoice, which has part numbers and what labor involved. You can lookup the cost at your local dealer. As I recall, it does require programming.

@Clanaim - this issue can be a can of worms
A dealer repair will use a reman part sourced thru their parts network
I suppose you can buy one outright from a local or online benz parts house though as @traxem noted its a mechanical and software routine since its an electromechanical gadget

Oh okay, I looked at your invoice. There are no charges? So dealer repaired it for you with no fees?

Yes. I have extended warranty.

Did they unplug the actuator in the rear diff to see if the humming goes away? You’ll lose 4Matic, but the problem will go away until someone comes up with a fix. I find it difficult to believe that MB designed the rear diff to be a 100% throw away part.

Think they reman the dead ones at some centralized joint (?)
Rebuilding at dealer sites would hold up service bays and jack up labor costs

Disconnected the wire. Haven’t changed it yet. It’s quiet now. Thinking seriously about getting rid of it.

Why is yours not being covered under warranty?

So they could sell me the damn parts and let me rebuild myself! I’ll never own another MB. Customer service is crap and the cars are crap and just cost a fortune for R&M!

I’m over this car!

Guess you a bum sample
A buddy had a “reliable” lexus gs ... nice brand new zippy car when it was on the road ... though at least 25% time was at the dealer for something or another from loose trim to rattles to cels to bad gas cap to leaky shocks to dead trunk lock to bad fuel pump to ... you get the idea
Dumped it after 39 month lease and got a e550 and still has it and that one only at the shop for oil changes nothing else thus far in >3yrs still has same brakes tires etc lucky twit

Oh ... luck of the draw and you got a problematic vehicle

 

[Mach2burnout]

Nah, I think the MB 4-Matic vehicles are just problematic in general. On the earlier models they had bearing issues in the diffs. The CLA’s are following right along with the issues they are having. This thread pretty much shows that it is not a few of them, it is all of them. If you haven’t had a diff issue in your cla 250 4-matic then get expect to in the near future.

If thats the case wonder if someone in the design chain underspecd the line of rear diffs cuz then that would make sense for premature or unnecessary wear
But then they usually overengineer so thats odd
