[98ML320]

I have been trying to figure out this issue for the past year with no luck. Last year I had an issue with this strange vibration, almost like grinding, and I could feel it through the gas pedal and it would happen when I let off the gas at about 70 mph. This year I have that same issue, but this time it happens when I have my foot on the gas at a steady 70 mph. Though it had something to do with the transfer case, seeing as there were metal shavings in it, but installing a new one did not fix the problem. Any and all help is greatly appreciated!

So many variables invloved.

U-joints, cv axles, center support bearing, wheel bearings, possible the torque converter and other items.

Does it appear to be any particular side or or corner of the ML?

Check ALL the belt driven items first. Could be a bad bearing in one of item at that rpm.
