Can anyone tell me if I can put a solid flex disc like the one at the diff on the front end of the drive shaft and what the ramifications might be if I did so.
I am tired to putting in the so called soft disc's, they just pound out in 20K miles.
I notice that the Diesel cars have a solid one in the front.
Also is there a way of checking the front engine mounts for condition?

I believe the disc at the front is that way for a reason. Most of the torque that comes from the transmission is absorbed by the cushioning and bending of the disc. If something solid and more stiff were in there then you might have issues and wear on major components from the torque force and rattling of the transmission.

Check, typically there are only one set of engine mounts on that engine. You would have to check the height of a new engine mount compared to your existing engine mounts to see if they have collapsed, and need replacement. Buy a name brand or genuine MB engine mounts. Stay away from any Uro parts.
