Corner jack points
Has anyone used wood to protect the corner jack points when lifting? The middle jacks points covered in the manual seem a little intimidating since it doesn't support jack stands along with comments about the material the under carriage is made of.

When I lifted mine to change out the wheels and verify the screw points on my side skirts, I used the "pucks" that you place on the jack. Those didn't damage the jack points on the side of the vehicle. Only thing though, is that it was quite difficult to find them, since my car is low and has the side skirts on them. Much easier to find when the entire vehicle is lifted. I wouldn't think that wood would damage the points, as long as they're not too large to contact other portions of the under carriage or the side of the vehicle.

I lift my car several times a year to swap wheels, clean the wheel wells, etc. - using a floor jack under the center, circular jack points. No damage whatsoever and it allows me to lift the entire front or rear of the car at one time. My aluminum floor jack has a rubber insert in the center of the lifting disk, which is nice. I also lower the vehicle onto jack stands at the side jack points for safety - especially if I'm gonna crawl under there for any reason. I haven't noticed any deformation of the side jack points from resting on jack stands. I've never actually lifted the car from the side jack points. I'm sure they're strong enough but I would feel more comfortable doing that using one of those slotted puck setups. I just don't like lifting and tilting my vehicles from those side jack points. I prefer to lift the car from the front or rear - evenly - from the center jack points.
I wouldn't trust wood. I've seen wood blocks split and break if the grain is going the wrong way. You've got a $100K car. Invest in a set of $50 jack stands.

Also on the back middle lift point. The diagram shows just forward to the differential? I'm unable to put my eyes on it. Mercedes is the same, but you can see a area for the jack to mate.

Many thanks. Are the rubber inlays (jack stands) something you can purchase from auto parts stores?

Yes, I struggled to locate the exact rear jack point myself. There's no easy way to see under there. Like most cars, it's just the differential itself.

Thanks for the replies. My Sunday project will have to wait until next weekend. Went to 3 auto part stores and no pucks for my jack stands or floor jack. I've ordered a couple different sizes for the floor jack that were close to the measurements I took. Once I get a puck that fits or close enough I'll zero in on jack stand pads. Wish I would have kept the puck from the Benz because I probably could have made that one work.

Bought a bunch from Amazon.
Hard rubber and has done a great job protecting the lift points.
I use a hydraulic floor jack and place the puck on the 5 inch diameter lifting saddle.
Good luck.

LOL - nope. Schwaben makes these specifically for their aluminum jack stands. Hockey pucks are too brittle. These have way more flex. I've seen pucks break while playing hockey (in cold weather)! Wouldn't trust a hockey puck to hold the weight of my car in any weather.

The tower is nice. I have 4 of these. All aluminum.

Agree. They are super nice. Much prefer the flat base over the tripod or 4-leg designs (easier on the garage floor). And they're lower than most jack stands (10.75") which is great for a low vehicle like the LC. These are the protectors I use: https://www.ecstuning.com/b-schwaben...ors/3107838kt/
Clean both surfaces with alcohol and attach with 2-sided tape - and you won't have to worry about them falling off and rolling away.
BTW - from what I've read from professional mechanics, and also the floor jack instructions - it's not advisable to rely on 4 jack stands to hold the car up. 2-at-a-time only with the wheels chocked. The concern isn't the strength of the stands. It's the potential of the vehicle falling off the stands if pushed. I personally always leave the floor jack in place for added safety.

I have two jacks that I use simultaneously with the towers as a backup.
I have heard of some many people that have had close calls with cars falling off the jacks or towers.
This includes my son. I got mad at him for being unsafe.
Also, thanks for sending the info on the protectors.
