Hmm, I'm referring to the lift points further inside. They are at places where you have to stick your head low to the ground to see them.

I bought a Torin version of this portable jack (see link below). My opinion of emergency jacks that come with cars is that they are almost one time use,throw aways.
This alternative fits under the car just like a normal jack. Just add a hockey puck inside the case. It probably weights at least ten pounds, and is is sturdy.

Wow, I didn't know the emergency jacks are that flimsy.

I got a Flat tire this morning on the front passenger side wheel. I will be using the jack and tools provided by Mercedes to change out the spare. Do I just place the jack under the posted pic above? Any tricks or tips out there for a noobie?


Thank you

For the factory sissor jack, you should use the side jack points.
That jack is only good to lift one wheel, not the whole front.
There are plastic pads just inside the side rockers.
Sometimes there is an arrow, on the side skirt, pointing out where they are.

Thanks for clearing that up, Are there any pictures or will it be apparent once I look under the car? I'm guessing it will be in the manual somewhere. Should I inflate the spare before putting it on and should the parking brake be on. Thanks guys

Right, definetly make sure your spare is fully inflated.
They tend to be low from being ignored for years.

Those side jack points will be a plastic rectangle with a rectangular depression in them.
The jack fits into that depression.

Definetly set the parking brake.
Also put some wood blocks (or similar) in front and back of the tire, that is diagonally opoosite the one you are lifting.

Don't lift any higher than needed, to just clear the tire from the pavement.
Overlifting can damage the jack and also make it wobbly.

For lugnuts,

Break loose with car lifted but tire barely touching ground (just enough so it wont spin). Dont fully loosen till tire is in air.

Tighten as much as you can with tire it in air, then just barely touch tire to ground to put final torque.

There is also a guide stud (in trunk) that might help you remove and install wheel without smacking it against the rotor.

Really helpful stuff , Thank you. Not sure if you know how the wheel locks work, but I'm pretty sure mine has them.

So any tips on jacking the back up to get both wheels off for tire change out?
or spots to put jack stands to support the rear?

I broke down and bought a QuickJack when Costco had them on sale because I could find a way to safely jack it and then place jack stands. That way I can jack all the wheels and not worry about how to jack the back and support it safely at the same time. It works well - just make sure you either get one of the longer models or the extension option.

I have a parking/service lift I just don't see any good spots under the rear to put jack stands. I usually park a car , raise up then lower it on stands until the tires are free then remove the wheels.

C130AMG

That was my issue. There is only one spot on each side in the back that seems safe to lift by and that’s the same place I need to put jack stand. Thus the QuickJack which functions as both.

I lift the back from the differential using a piece of wood to distribute the load.

BDC90

I thought about that but was afraid of breaking the cooling fins.

Cla1111

It didn't brake them. They scored the wood. I think it's iron.

On the other side, yesterday I have crushed the front jacking pad. It was very scary seeing the car moving down (one inch maybe) in that crashing noise! :-). It came out in 3 pieces. It's not rubber, it's just a piece of hard plastic. It's hollow, with some reinforcement inside. I have probably pushed a bit off center, applying weight to the bolt.
I need to find a replacement part number now.

Here's the MB part that snaps into the jack points:

Thanks, they look nice, but I think they are for the side jack points. Those jack points are made of rubber and they work fine for jack stands.
What I have destroyed is the plastic puck of the front central jack point, located under the subframe. I will have to find a new one, or make some piece of wood.
I think that the car was too inclined (I was lifting it to remove the jack stand after I replaced the transmission mount) and the jack applied pressure on just one side of the puck.

Valvestud

No, your lifting wasn't the issue per say. The part is junk and I destroyed mine as well. I was able to substitute a piece of aluminum rod that I had turned down one end to fit the hole left by the old part. I have purchased a new plastic one and will install at some point. Had no idea it was plastic until it blew apart.

If interested, the part is 0029976186. Less than $10.
