There are no grease fittings that I can think of. Grease fittings have been almost non existence on MB's and most other cars for about 30 years. Modern components are sealed and seem to last longer than the units that they replaced that were greasable.

I'm not sure about your car, but the 123 cars of that era had flush type grease fittings on the door hinges and I can't think of ANY other grease fittings on the entire vehicle.

Don't fight it. Sealed components are here to stay. In my experience, greasable components have to be greased until they wear out and then you replace them. Sealed components on the other hand, seem to last just as long or longer and when they wear out you replace them the same way. The difference is that you don't have to worry about keeping up with a messy grease gun.

If your old enough to have ever greased many fittings, this probably seems all backwards to you, but it works out fine in almost all cases.

Good luck,
