Car Forum / Mercedes-Benz Cars / March 2008300D Power Antenna
I have recently replaced my power antenna mast and now cannot keep it working. The motor works fine, but the mast only intermittantly goes up and down. I suspect bad lubrication, but do not know what to use. Suggestions?

What I did do, though, was crack open the motor case and clean it out. It was full of plastic shavings, and I may well have lubed up a couple of the rollers in there. I certainly operated the friction mechanism so it'd move freely. You don't need to take it very far apart, basically just take the lid off and vacuum/blow the crap out. good luck, -tom! -- > > > I have recently replaced my power antenna mast and now cannot keep it > > > working.

I cleaned mine out and freed up the tension roller that keeps the plastic pushed against the pulley. Water, salt, etc runs down the mast and into the mechanism. I'ts very easy to remove the whole antenna from the car, remove cover and clean/lube. > > > I have recently replaced my power antenna mast and now cannot keep it > > > working.

Yeah, basically you spin the nut off the antenna where it "attaches" to the body on the outside, remove the bolts that hold it inside the trunk, and drop it out. Then there are three or four bolts that hold the lid on the motor unit (and you'll need to disconnect the power connector, since it's not got a lot of slack). -tom! -- > randallbrink wrote: > > > What I did do, though, was crack open the motor case and clean it out.
