The wiper arm is connected to the wiper linkage and holds the blade. Why do you need to replace windscreen wiper arms? Over time, the arm can be bent and damaged, especially in winter when it moves heavy snow and ice.
If the windscreen wiper arm runs poorly, you know it right away, because the windscreen wiper leaves streaks, rattles over the windshield or does not move at all. This presents a problem even if it is just leaving streaks, because it reduces your visibility when you are driving in rain. Our guide shows how to replace windscreen wiper arms in 5 steps.

Step 1: Remove the cover of the swivel nut. Use a small flat-head screwdriver and pry off the cover of the swivel nut to remove it.
Step 2: Remove the arm retaining nut. Use a ratchet, extension, and socket of the appropriate size to remove the arm retaining nut.
Step 3: Remove the wiper arm. Remove the arm by pulling it up and pulling it off the boom.
Note: On some vehicles, the wiper arm is pressed down and requires a special puller to remove.
Step 4: Mount the arm on the linkage. Mount the arm back on the linkage bolt.
Step 5: Install the arm retaining nut. Attach the arm retainer to the rod and tighten with a ratchet, extension, and socket of the appropriate size.
