My wonderful CD manual has a W124 procedure for replacing motor mounts in the 300SE 88-91 sections. When I looked in the 300SD section, there was mention of removing one of the throttle control rods. Nothing similar mentioned in the W124 procedure.

What should I remove or loosen before lifting the engine? Re archived posts, do I have to remove the upper radiator hose? Should I *not* use a jack under the oil pan?

There is no mechanical throttle linkage between the M103 and the chassis. It is a cable. You should remove the fan shroud (if I were doing it, the fan blades as well. I believe you will have to release the tranny from the crossmember as well, but not 100% sure (It couldn't hurt) You will have to block under the engine and bellhousing to safely raise the engine/tranny assy high enough to get the mounts out. Great care on the sump of the M103. It is aluminum.Yes, do remove the upper radiator hose. If you don't, there is a remote possibility that you might crack the neck of the plastic radiator tank. Good luck. May the Force be with you..

No matter what you fix, there will always be something else to fix.. "Warranty" is just another way of posponing the inevitable.

I don't know if you got around to changing the mounts yet, but I changed mine ~2 weeks ago. I guess I'm dumb enough to "just do it" so with hex wrenches in hand went at it. It's a piece of cake. I didn't disconnect anything, just put car on stands, released the mounts on one side, jacked the engine (use a piece of 2x4 to span the oil pan)this rotated the engine more than raised it,changed the mount and the repeated on other side. Remember to position the engine shock prior to lowering the engine and reattaching the engine to the mount.
Don't know if this helps, but thought I'd pass it along.
