What is the Rear Windshield Wiper Arm?
The rear windshield wiper arm is a metal or plastic arm that connects the wiper blade to the pivot mechanism inside the vehicle. The pivot allows the arm to swing back and forth, moving the wiper blade across the rear window glass to clear away rain, snow, dirt, and debris.
Without a functioning wiper arm, the wiper blade will not be able to contact the glass properly. This can greatly reduce visibility out of the back window while driving.
Some key components of the rear wiper arm include:
– Arm bracket – Connects the arm to the pivot mechanism. Usually made of durable plastic or metal.
– Hinge joints – Allow the arm to fold or pivot as needed.
– Attachment adapters – Connect the wiper blade to the arm, often using a hook or pin system.
– Linkages – Transfer force from the motor to move the arm.
– Springs – Help return the arm to the proper resting position.
Why Does the Rear Wiper Arm Need Replacement?
There are several common reasons the rear windshield wiper arm may need to be replaced:
– Normal wear and tear over time. The continual motion of the arm over many miles can cause joint wearing, stripped gears, bent components, etc. Most arms have a typical lifespan under normal use.
– Accident or collision damage. If the rear wiper mechanism gets smashed or impacted, the arm can bend or break entirely.
– Exposure to weather elements. Things like sun damage, rust, corrosion over many years outdoors can degrade parts.
– Stripped or broken pivot joints. Key hinge points on the arm can wear down or tear, preventing proper motion.
– Broken springs or linkages. The interior spring and linkage system is prone to fatigue cracks or snapping.
– Burned out wiper motor. A bad motor can sometimes damage the arm when it seizes up.
– Upgrading to a winter wiper blade. Some winter or all-season blades require a heavier duty arm.
– General lack of effectiveness. Over time the arm may lose pressure and ability to clear the window fully.
When the wiper arm is struggling to move smoothly across the rear glass, generates noise, leaves streaks or unwiped areas, or fails to return to the resting position, a replacement is required.
Cost to Replace Rear Windshield Wiper Arm
The total cost to replace a rear windshield wiper arm can range from $50 to $250 or more, with most vehicles costing between $75 and $150 for parts and labor.
Here are some of the factors that affect overall replacement costs:
– Vehicle make and model – Costs can vary significantly between vehicle brands and models. More complex wiper systems on luxury cars tend to cost more.
– Arm type – Basic plastic arms tend to be cheaper than heavier metal arms common on trucks and SUVs.
– Single arm vs pair – Sometimes only a single damaged arm needs replacement, other times both left and right arms should be swapped as a pair.
– Additional repairs – If surrounding parts like motors or linkages also need replacement, costs add up.
– Shop fees – Labor rates, trip fees, and shop supplies can vary between mechanics. Dealerships often charge more than local garages.
– Parts brand – OEM factory arms tend to be priciest. Aftermarket or used parts can sometimes save money.
– Location/region – Prices range across different areas due to labor costs, taxes, overhead, etc. Urban areas are generally more expensive.
To give an idea of price range:
– Basic plastic arms average $50-$100 for just the part.
– Complete replacement at a shop often ranges $100-$200 including about 1 hour labor.
– Higher-end cars with dual metal arms can be $200-$300+ in some cases.
Parts Cost
For the rear windshield wiper arm itself, prices typically range from about $50 on the low end, up to $150 or more for higher-end parts. Pricing depends on the specific vehicle’s arm type and materials. Some examples:
– Simple plastic arm for an economy sedan – $50-$75
– Hardened plastic arm for mid-size SUV – $60-$100
– Heavy duty metal arm for pickup truck – $90-$150
Many luxury and performance models have special adaptive arms with complex pivot joints that can exceed $200 in some cases just for a single arm.
Aftermarket or salvage yard arms tend to range from $50 to $100 less than OEM parts in most cases.
Labor Costs
The job of actually removing the old wiper arm and installing a new one has a labor time ranging from 0.5-1.5 hours in most cases, with 1 hour being typical for most vehicles.
At a shop rate of $100 per hour, this puts total labor costs in the $50 to $150 range, with $100 being average. Luxury or performance car shops may charge $150 per hour or more, raising labor prices.
DIY arm replacement can avoid the labor fees, but requires automotive tools and expertise.
Other Potential Costs
– Some mechanics will add on service fees like charging for shop supplies/materials or disposal fees for the old part. These typically add $10-$30.
– If the wiper motor or other components also need repair, expect added labor and parts costs.
– Trip fees may be charged for mobile mechanics or roadside assistance calls.
– Sales tax will need to be added onto parts and labor.
– If new wiper blades are needed, add on $10-$30 per blade.
– On rare occasions, a stuck or damaged wiper arm can scratch the rear glass when removed. Windshield replacement due to damage can cost over $500 in some cases. Avoid this by using a protective cloth when removing the arm.

When to Replace the Rear Wiper Arm
Here are some signs that indicate it is time to replace a worn-out or damaged rear windshield wiper arm:
– Streaks or unwiped areas remain on rear glass after use.
– Wiper arm is visibly cracked, warped, or broken.
– Wiper skips, bounces, or loses contact with window at times.
– Arm gets stuck mid-cycle and needs manual returning to rest position.
– Worn pivot joints causing sloppy or loose wiper motion.
– Rear wiper making grinding noises, squeaking, or chattering.
– Arm corrosion visible – rust eating away mounting points.
– No motion at all when the wiper switch is activated.
– Rear window washer spray missing glass or spraying errantly.
– Finding the proper resting park position is difficult.
– Wiper fluid leaking at joints – rusted out seams.
Waiting too long to replace a declining wiper arm can allow glass damage from poor cleaning. Catching the problem early provides the best visibility and safety. Most mechanics recommend inspecting and testing rear wiper operation at least yearly as maintenance.
How Long Does the Rear Wiper Arm Last?
The average lifespan of a rear windshield wiper arm is typically 3-5 years in most conditions. However, many factors affect longevity:
– Make and quality of the arm – cheaper arms tend to wear out faster
– Material – plastic arms degrade faster than metal in sun and winter
– Usage frequency – arms on vehicles in snowy areas wear faster
– Sun exposure and UV damage – causes cracking
– Grease and grime buildup – can restrict motion
– Driving conditions – frequent bumps and debris hits accelerate wear
– Number of articulating joints – complex arms break down sooner
Signs of aging like cracked housing, sloppy joints, or stripped gears indicate time for replacement before total failure happens at an inconvenient time. Periodically inspecting and operating the rear wipers helps spot problems.
For preventative maintenance, many vehicle owners plan to replace the rear wiper arm at least every 5 years or 50-75k miles as the effects of wear add up over time. This helps avoid being stuck with a non-functional wiper when driving in poor weather conditions. Catching problems early also prevents damage from arms that detach at speed. Following the vehicle manufacturer service schedule is recommended.
Conclusion
Having to replace a failed or aging rear windshield wiper arm is an annoying but unavoidable maintenance need for most vehicles eventually. Costs for a typical single arm replacement at a shop will run between $100-$200 in parts and labor. Several factors like vehicle make, arm type, and service location can alter the total bill.
Carefully inspecting the condition of rear wiper operation and watching for signs of a deteriorating arm allows owners to plan service in advance rather than be surprised by a sudden failure. With some price research and shopping around, drivers can find quality professional replacement service at affordable prices to keep that back window clear.
