W116, BENZ AID - COMMON QUESTIONS AND ANSWERS

85 td can rear bearing cause thumping?

There is a small amount of play top to bottom and left to right in my right rear tire. Not much, but more than on the left. With the car supported and the transmission turning the thumping is clearly comming from the outer axle joint/hub bearing area. With the axle out of the hub it seems fine (no looseness). I did not remove it from the differential. I would be more inclined to do the axles myself than the bearing so I talked to my mechanic about having him do the bearing.

1974 Shortcoming: Dashboard Instruments?

We just bought a 1974 280C from the second owner.
Jack, reluctantly sold his "baby", because, now entering his late 70's, hip replacements have made entering and sitting painful for him. He broke the map pocket on the driver's side swinging his legs into the seat.
The speedometer's 76000 miles appear to be reasonably accurate... tires mounted in 2001 were recorded @ 71000mi (and there aren't that many miles to drive on a small island like this one), etc. He has kept the coupe immaculate.
Is the dashboard instrumentation a weaklink on the W114?
The VDO quartz clock is non-functioning. Jack velcro-attached a tiny digital clock to keep time.

300sd engine swap...parts replacement recommendations?

I am changing the engine in my 82 300sd (due to low compression on one of
the cylinders/poor starting in ontario winters). I want to be sure I do
everything that should be done while the engine is out of the car.
I have ordered the front main seal and a bunch of other stuff.........but
I see no mention or guides available for the rear main seal. I'm not sure
if the engine being transplanted should have a new rear main seal, or if it is an easy job....... or not.

Anyone with any experience or info on this?

1977 300D coolant leak

Last year my parents bought me a 1977 240d with a 300d engine. I love the car because of its old style and drove it for about 4 months before pools of coolant started to appear under my car. I am wanting to fix my car now that my dad recently passed away and i need to know if anyone could help me by finding out what the cause is. I have had people tell me its a freeze plug behind the engine. All can tell is that its leaking between the engine and transmission. if anyone could answer this for me i would appreciate it and i would know that i must purchase a freeze plug.
