Try working for Ericsson - a bunch of Swedish engineers - we can't say sentence without at least 5 acronyms! Mix that with Swedish and every document looks like alphabet soup.

been there/done that/got the Vibration T-shirt (see my previous postings).

To all with front end vibration - LISTEN TO LARRY. I had a terrible time with front end vibration between 72-77 mph....had new tires, shocks, balancing, blah blah blah. Then I took it to a MB dealer and had them balance it on a 9700 - what a difference - new car feel with 252K miles! Smooth as silk at interstate speeds, all day long. Repeat after me - MB front tires MUST be properly balanced. MB front tires MUST be properly balanced....

Yesterday I replaced the center support bearing, rubber mount, rear driveshaft bushing, and front and rear flex discs. Drove 275 miles - no difference :)

The bearing was little loose and I heard the balls spin around inside. The mount was cracked, but not enough for light to shin thru. that mount is VERY tough. I have seen (yesterday on a 76 450SL) mounts where the middle was completely separate from the mount, though. Three washers were missing off my old flex discs.

This may not apply in all cases, but in mine, I think unless the rubber fails miserably, it may not need to be replaced....

On the test ride, shifting into 3rd gear makes the ride a bit smoother. But not at 77 MPH. At 77, in '3' or 'D' there is something not right. I am pretty sure its been there thru several sets of tires, a new set of front wheel bearings, etc etc.

I'll have my tires checked on a GSP 9700 anyway, just to be sure. could be that something is causing all my tires to be chewed up a certain way :confused: .

Thanks.
