Common Questions About Your Windscreen Wiper Arm Replacement
What Factors Determine Quality in Windscreen Wiper Arm Replacement?
The quality of a windscreen wiper arm replacement is fundamentally determined by three engineering factors: the precision of the mounting spline fit (preventing wobble), the material composition of the arm (resisting corrosion and stress), and, most critically, the calibration and fatigue rating of the internal tension spring. I always check that the spring delivers the specified pressure (measured in Newtons per square meter) required for the blade contact patch.
How Do I Measure for the Correct Wiper Arm Length?
You typically do not measure the arm itself, but rather confirm the length of the wiper blade that the arm supports, as well as checking the specific OE part number or the VIN compatibility. Since the arm’s geometry (the distance from the pivot point to the blade attachment) is fixed and unique to the vehicle model, verifying the make, model, and year against the manufacturer’s compatibility chart is the only reliable method for obtaining dimensional accuracy.
What is the Significance of Alloy Composition in Wiper Arm Durability?
The alloy composition dictates the material’s ability to resist metal fatigue from repeated cycling and corrosive degradation from weather exposure. Cheaper arms often use thin-gauge steel which quickly loses tension or develops stress cracks. I look for arms constructed from heavy-duty, often proprietary, corrosion-resistant aluminum or steel alloys that maintain their structural integrity and spring tension over a projected service life of 3–5 years.
Should I Replace Both Wiper Arms Simultaneously?
In most cases, yes, I recommend replacing both arms (the driver and passenger side) at the same time, especially if the original arms are the same age. Wiper arm failure is typically due to spring fatigue over time, and if one arm has failed, the other is likely close behind. Replacing them as a pair ensures symmetrical contact pressure and consistent wiping performance across the entire windshield surface.
How Do I Know If I Need a Wiper Arm Replacement or Just a New Blade?
If your wipers are chattering, streaking, or skipping, start by replacing the blade, as this is the primary wear component. However, if a new, high-quality blade still performs poorly, or if the arm itself is visibly bent, cracked, or if you can lift the arm away from the glass easily, then the tension spring has failed, indicating a full wiper arm replacement is necessary.
