Applicable Models:

Mercedes-Benz R170 (1998-04)

Like most plastic parts that move, door handles eventually crack or break. The R170 SLK offered body-colored handles. New replacement handles are available for some colors. Right side handles are fairly affordable, because they don't have lock cylinders. Cost for the driver's side varies depending on lock style (transponder, etc.).

The exterior handles can be removed with the door panel still in place. (Our project car's right-side panel was already off; we used it for demonstration purposes.) The only tools required are a 4mm hex/Allen wrench or bit and a Phillips screwdriver.

Peel the weather stripping out of the door channel until the screw hole (purple arrow) is accessible.

Use a 4mm hex/Allen wrench or bit to loosen the screw.
Figure 2

Use a 4mm hex/Allen wrench or bit to loosen the screw. The right side door is reverse-threaded (turn right to loosen). Pull the handle out and tighten the screw lightly.

The handle will stick in this position.

The door panel was off for other projects, so the outer window weather stripping was easy to peel back for better access to the lock/guide screw.
Figure 4

The door panel was off for other projects, so the outer window weather stripping was easy to peel back for better access to the lock/guide screw. Otherwise, the cover plate can be removed by taking out two Torx-headed screws (one screw hole indicated by arrow; please see the door panel article for further details).

A 4mm hex/Allen wrench/bit is used again to unscrew the lock (driver's side) or guide (passenger's side).
Figure 5

A 4mm hex/Allen wrench/bit is used again to unscrew the lock (driver's side) or guide (passenger's side). This screw is threaded normally (counterclockwise to undo).

The guide or lock is now free.
Figure 6

The guide or lock is now free. The hex screw (purple arrow) is captive in the hinge strap so it won't fall into the door panel.

Remove the screw, which secures the handle to the hinge strap inside the door.
Figure 7

Remove the screw, which secures the handle to the hinge strap inside the door. For installation, use thread locking compound on this screw.

Slide the handle toward the rear of the car.

The handle comes free from the door.

The handle can now be cleaned, painted, or replaced.

The handle can now be cleaned, painted, or replaced. Installation is the reverse of removal.

Comments and Suggestions:
Dave Comments: This is not the same process for the driver door : I can't find any how to articles for it.

  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.
