W124 Jacking Point Pads
 

I went to jack up my 300D and put it on stands, and found that two of the wedge-shaped rubber pads under the jacking points were gone. Anybody know the part number for these? Is there some kind of hardware that holds them on that came loose, or do they just snap into the holes I can feel on the underside of the edge of the body?

They just snap in abd they are only a couple of bucks at the dealer.

Put a little water proof wheel bearing grease on the new pads, they will go in better and the grease will prevent rust. I think I payed $9 each for mine.

I would not recommend using a petroleum based grease. It could attack the rubber. Just use some silicone spray lube, then push and twist and they will pop right in.

I was missing one and bought it at the MB dealer for $6. Went in with no problem but the lube suggestions probably will make it go in without any problem

I thought silicone was bad for rubber also... or is it only bad for plastic, hence why many people warn against using interior protectant containing silicone?

:confused:

I didn't use anything when installing a missing one on my W124. I just placed the pad on top of a floor jack's saddle and raised the jack until the pad was firmly seated.

I didn't use grease to lube the rubber, I used it to prevent rust underneath the pad. They have a lip and water and crap sits inside causing rust. Grease is an excellent rust proofer, I don't care if it eats the pad their cheap I'll replace them every few years.

Alex, the jack pads have a center pin that slides out. Press the jack pad into its slot and lightly tap the center pin with a hammer until it's fully inserted.

Use dielectric grease. It is also called silicone grease, or bulb grease. Auto stores mostly only sell it in .25oz tubes. HomeDepot shows a 6oz can for about $10 but I can not find it in the stores (order online?); or a serious electrical supply place should carry it. Will accomodate your rubber lubrication needs, as well as protect the surrounding metal from rust. I am guessing that this is the main ingredient in the Mercedes whiz-bang subframe bushing lubricant. If you go to the local parts place, just ask for bulb grease or you will get the 'deer in the headlights' look.

For you purists, the spray silicone contains petroleum distillates as propellant (probably insignificant but this is for the purists). The diaelectric grease does not contain these, and its original purpose is to seal electrical connections from moisture with zero conductivity.

Pep Boys sells CRC dielectric grease in a 3 or 4 ounce can. You squirt it out through a tube

I used rubber lubricant out of the jug that I use for lubricating tire beads when sealing tires. It is designed for the purpose of lubricating rubber with no ill effects.

Have a great day,
