I recently started noticing a slight humming sound coming from the front of my SUV. I took it to the service center and was told the front differential needs to be replace at a cost of $3668. 00. I was told they just go bad and also they just replaced two more here lately.

I bought a 2006 mercedes 3 years ago thinking I would have a car for a lifetime boy did I go wrong. In the past 3 months I have had major problems and mercedes doesn't care. The first issue I had to replace the crank shaft $6000 plus for repair I almost went crazy so I started researching on the internet and found out there was a class action law suit for this issue so I phoned mercedes and they agree to pick up half of the repair. One month later car starts making winding noise take it back to them and now they say it is the front differential $5500 to repair I start to research that on the internet and there are so many complaints for my same issue on the same year and model so I go back to mercedes however this time not willing to help. How many complaints is it going to take for something to be done to such a powerful company like mercedes. I truly do not think this is fair and us the consumers are being ripped off.

At approximately 70k miles, I began to notice a low-frequency whining noise in the front end of my ml-350 at speeds above 40 mph. The noise became more prevalent when I took my foot off of the accelerator at higher speeds. First, replaced all four tires with michelin "latitude tour hp" - $1,300 (including alignment). The noise still occurred. Next, took to mb specialist, who recommended both wheel bearing be replaced - cost $425/side. The bearings were replaced and noise still occurred. Mb specialist recommended checking differential oil for metal - found lots of metal fragments in differential oil. Installation of new differential was ~$3,500. Mb specialist stated that his parts distributor said that they sell at least one-to-two late model ml-350 front end differentials per month. In my opinion, it seems as though there is a flaw in the differential's design or manufacturing process, as I seen several reports of the same differential issues with [relatively]-low-mileage/late-model mb ml-350 suvs. I would like to see mb research this issue, and possibly instate a recall or reimburse mb owners who've already affected costly repairs on their low-mileage ml-350's front end differentials.

2006 mercedes Ml350, front differential worn at ~75000 mileage, that could lead to lockup at any time if not fixed. From talking with the three mercedes dealerships in my local area, it seems there is a very high incidence of front differential problems on 2006 ml's.

Front differential for my mercedes ml 350 year 2006 needs to be replaced after only 52000 miles.

Grinding noise in front diagnosed as failed front differential.

Took car to mb dealership in north olmsted ohio because front end of car and steering wheel started shaking and vibrating excessively when the car was driven in excess of 60 mph. Car drove fine under that speed. I almost was caused to drive off of road at multiple points because of excessive vibration and lack of steering control. Condition did not occur at lower speeds. Car was 1 week outside of mfr warranty. Was told by mb dealership that car needed new front differential. I called mb national to complain about an alleged luxury car's front differential failing only after 40k miles. They told me it was not their problem. Car continues to have problem to this day (1 year later). I was told that the car was safe to drive. I have since been looking for a used differntial because a new one w/install is over $3k. It seems as if I am not the only ml owner experiencing these problems. Mb went with a new 7 speed transmission that year which may lead to problems.
