YES folks, yet another D.I.Y. Video. I'll keep working on more of them (Brakes, Air filter, MAF sensor, and others). This was the easiest job ever but it was also the hardest job as far as holding the camera still. lol

Newbee here!

I enjoyed both of DETAIN's videos ( transfer case & diffs ). After reading all the posts on the transfer case oil-change procedure, I got the impression that this was something that had to be done when the truck had around 90K miles on it. Since the Frau's ML has only about 13K on the clock, I am probably WAY premature in worrying about changing the oil in any of the diffs yet, but I am always eager to be educated by the experts. I have a related question for all the DIY ML owners, regarding the ML running gear. Before I bought the ML, I researched the various types of all-wheel-drive arrangements, to get all the pros & cons of the various configurations. For example, H2 Hummers have a Torsyn center diff, and BMW AWD trucks have planetary bands & clutches for directing the power to the four wheels. The ML, on the other hand ( so I read! ) has an "open" center diff, so that power is directed to the "traction" wheels, by selectively braking the "slipping" wheels. SO --- is the open center-differential, the same component as the Transfer Case? Also, is Low Range accomplished in the T-case, or the tranny? My Wrangler is 4-Wheel drive, not AWD, so there is no center diff, and low-range is effected in the Xfer case.
I have not yet had the occasion to get under the ML, but DETAIN's video of the Xfer-case looks awful small to contain a medium-duty set of differential gears. Has anyone on this forum had on of those buggers apart??

TY for the video Detane! All of us on the board appreciate you taking your time to do this. I even vote for STICKY!

Those O-Rings dealer only items? I'm not having much luck at Autohaus.

I am not a fan of these DIY videos, unless they are factual, because they become impressionable to the viewer. Viewers tend to follow the instructions of the maker and use what products they see being used in the video.

Detane's video shows the use of Mobile 1 75W-90 gear oil which is considerably thinner than the 90W required by M/B. In fact the front differential requireS a straight 90W and the rear requires 85W-90, both having different part numbers at Mercedes.

More than half the members on this forum do not have an owners manual and those that do probably won't even check to see what weight is required. But the simple fact is that a thinner weight oil will cause more metal to metal contact in the gearing, thereby causing heat build-up and premature wear.

USE WHAT IS REQUIRED, NOT WHAT YOU SEE IN THE VIDEO.
