One of the most common things we do to our car is to jack up and safely support your vehicle. By now we should have all heard the story of the inexperience mechanic who went to jack up the BMW 318i E30 chassis and ended up jack up the vehicle by the gas tank (damaging the gas tank). German vehicles have a proper way for doing everything. To prevent damage to body-effects, such as a valance panel or rocker panel cover, you need to jack up and support your vehicle with jack stands at the correct locations. In this tech article we will go over safely jacking up and supporting your vehicle.

This photo illustrates the left side rocker panel below the door.

This photo illustrates the left side rocker panel below the door. Look at the two plastic covers clipped into the rocker panel (green arrows). Look under the car at these locations.

Under the car you will see a chassis pad (green arrow).

Under the car you will see a chassis pad (green arrow). This is where you can check the vehicle off from safely. This photo illustrates the left side front pad.

This photo illustrates the left side rear pad (green arrow) at the rear of the rocker panel in front of the driver side rear tire.

This photo illustrates the left side rear pad (green arrow) at the rear of the rocker panel in front of the driver side rear tire.

This photo illustrates the right side rear pad (green arrow) at the rear of the rocker panel in front of the passenger side rear tire.

Finally this photo illustrates the right side front pad (green arrow) at the front of the rocker panel behind the front tire.

Finally this photo illustrates the right side front pad (green arrow) at the front of the rocker panel behind the front tire. These are all safe places to jack the car up from.

If you have a long enough jack you can slide it under the middle of the engine compartment and jack up the car from the sub-frame jack pad (green arrow).
Figure 6

If you have a long enough jack you can slide it under the middle of the engine compartment and jack up the car from the sub-frame jack pad (green arrow). If your jack is not low profile it may hit the sway bar first. We do not recommend you jack up the entire front of the vehicle from the sway bar or any suspension component. In the old days these lower control arms were made of steel. Now they are made of aluminum that can bend and break.

This photo illustrates the underside of the front of the vehicle.
Figure 7

This photo illustrates the underside of the front of the vehicle. If your jack is low profile you can lift the car from the center of the sub-frame (green arrow). Make sure the vehicle is in park and the parking brake is applied.

If you need to jack up the entire rear axle you can jack it up from the jack pads (green arrows) mounted at the bottom of the rear sub-frame.
Figure 8

If you need to jack up the entire rear axle you can jack it up from the jack pads (green arrows) mounted at the bottom of the rear sub-frame.

Place the jack under the jack pad of the corner of the vehicle you want to work on and jack up the vehicle.
Figure 9

Place the jack under the jack pad of the corner of the vehicle you want to work on and jack up the vehicle. This photo illustrates the right front of the car being jacked up.

This photo illustrates under the right side of the car by the front of the rocker panel with the car fully jacked up.
Figure 10

This photo illustrates under the right side of the car by the front of the rocker panel with the car fully jacked up. Place the jack stand underneath where the frame rail meets the body. Our 129 chassis uses a unit body design. This means there is a front and rear sub-frame that bolts to the body and the body is used part of the frame. You do not want to put the jack stand under a thin metal panel that cannot support the weight of the car. You will damage the car. Place the jack under a strong piece of the frame. You can also jack the car up from the frame where the jack stand isPictured here and place the jack stand under the jack pad.

Lower the jack until the frame is resting on the jack stand.
Figure 11

Lower the jack until the frame is resting on the jack stand.

This photo illustrates that we are now under the left side of the car at the front of the rocker panel.
Figure 12

This photo illustrates that we are now under the left side of the car at the front of the rocker panel. We have jacked up the left front of the core and place the jack stand under the body of the car by a frame rail. Placing the jack stand under the frame allows the suspension to hang so parts can be removed. Follow this same procedure for the rear of the vehicle. Place the jack stands under the sub-frame away from suspension arms so you can remove them if you need to. To remove the jack stands simply jack up the vehicle again, pull the jack stands out of the way and slowly lower the jack until the wheels are on the ground again.

Comments and Suggestions:
Frostie Comments: Thanks for the comments and suggestions, but it's not a SL600 nor a R129!
It is something real special from 1960:
A Mercedes-Benz 300SL with a tubular frame!
That makes it so difficult just don't think of the price to damage something!.

  Followup from the Pelican Staff: Yes, I understand. Not a vehicle many get to work on. - Nick at Pelican Parts  
Frostie Comments: Do you have a nice jacking up instruction like this for the Mercedes-Benz 300SL 1960 ?
It has no unibody and I don't dare to lift it up for working underneath.

  Followup from the Pelican Staff: We don't currently have that tech article. If we get a chance to perform the procedure, we will be sure to document it.

I would grab a repair manual. It will have the procedure, special tools and torque specs.

Give our parts specialists a call at 1-888-280-7799. - Nick at Pelican Parts
 
TAB Comments: Don't jack up a sl600 with the leveling system unless you know what your doing. I did and half the fluid dumped out
