| Description of the problem | 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. |
