SOURCE: 1993 Mercedes Benz 300E, right rear squeak

Common causes for High-pitched noise from rear wheels are:

The wheel bearing: this is not usually dangerous in the short term, but I recommend contacting a mechanic and having it fixed. To test the wheel bearing, you lock front wheels, and jack up the car rear and spin the wheel (handbrake unlocked). If bearing is worn you hear a drone. When is the bearing, often car starts vibration above 40 mph.
Noise from bearing can be continuous, intermittent, only when steering, only when hot.

The brake pads: when brake pads are worn out they start making a squealing noise, in this case the noise is only when you brake or continuous. When you jack up the car the wheel may be a little stiff, but not necessarily.When brake pads are completely gone you also hear a scratching noise when braking. Inspect your brakes immediately.

Other suspension problems: Jack up the car as suggested above, check if the wheel has a slight play on the sides. Check all of the suspension components, suspension mounting points, and steering linkage for damage. Also, check the frame rail for wrinkles. It is very important that these components be in good condition, if you notice any problem here, go immediately to a mechanic.

Try doing the simple test above, reinstalling the wheel and working the tire back and forth. This is a common test for bad ball joints and wheel bearings.

SOURCE: 1988 Mercedes Benz - 300E , want to replace window switch

Hello, To the rear of the wood grain where the switches are, you should have a small piece of carpet that you just pull up and get it out of the way. You should see 1 screw. Remove the screw and gently pull up on the back of the wood grain. Now you will be able to change the switch.
I hope this helps.

SOURCE: need to locate fuel filter on 1989 mercedes benz


The fuel filter is located on the right rear underside of the car, just ahead of the rear axel area. You need to remove the cover to find it. It is the large canister next to the electric fuel pump.

300e tranny reverese uses clutch disk for B3 and therefore no external fix. You will need to pull the tranny out and might as well rebuild the whole thing.

I have a 1990 300e mercedes that will start but will only run for a few seconds then die? Does anyone have any suggestions on what it might be?

I don't know much about Mercedes, but that is exactly what most other vehicles will do when the MAF(mass air flow sensor) is faulty. It's always a good idea to find one at an auto wrecker, and try it. Or the fuel filter clogged? Hope this helps.

In all of the other forums the mechanics talk about replacing or checking the fuses on the OVP which is the Over Voltage Protection Relay located on the right side of the engine compartment behind the battery. That might be a good place to start checking.
