What is the cause of sloppy BMW wiper arms?

Plastics and rubbers do not age well, over time they dry out and crack through oxidation. If you have sloppy / floppy windshield wiper arms the cause is due to dried / cracked out damper bushings. This is a very simple fix that will make your life a lot less stressful by never having to readjust the arms by not returning them back to their normal resting spot on your windshield.

What is the replacement procedure?

The fix is simple. First, remove the wiper arm plastic cap. If your plastic wiper arm caps are cracked, faded or missing we sell replacements which can be purchased HERE. Next, remove the 13mm nut (on the E30). Remove the stack up of hardware until you can see the dried out and cracked rubber damper grommet, or what is left of it. The easiest way to remove is by using a set of pick tools and or small needle nose pliers. Once removed, obtain your new grommet. You may want to lube it up with dish soap or a little contact grease. This will allow the grommet to pop into place easier.

Simply press the grommet in the cutout so the sheet metal on sits in the groove of the grommet. Once in place, reassemble the arm in reverse order. Repeat for the other side and you are done. You can grab the arm and try to move it around to compar. You will likely notice a huge difference in slop. The biggest difference you will notice is never having to move the arms back up from drooping down after use.
