This is what I used. One came off by rocking back and forth. The passenger one, I had a hard time getting off.

The wiper arms were quite stubborn on my car the first time I ever took them off, despite zero corrosion. The times I've removed them after that first time have been much easier.

I find that repeatedly lifting the arm into the upright position, due to the force of the spring in each arm coming unloaded, exerts a shock force to the base of the arm that really helps break the taper. As I recall, I just do this instead of messing around with applying any sort of direct force to the base.

This hasn't been removed in years and my car is filthy from sitting for over a year. I've watched people fight with these things and all it takes is a few seconds the right way.

+1. I've done wiper arms on many cars, including cars 30+ years old, and never had as much trouble as the ones on the M. Though I think mine had never been off before. The guy wrenching on the line in late '96 must have been a beast.

Mine's a late 96 as well, perhaps we had the same guy?

It is corrosion. Spray penetrant, wiggle, pry (on wood shim). Can be a real pain. Consider anti seize when reinstalling.

The wiper arms can be tough to pull because they are a splined fit to each external stud from the drive mechanism.

That splined fit is the same reason why it can be tough to break a steering shaft from a U-joint, or tough to break an axle free from a wheel bub, or why gears can be tough to pull when you're doing transmission work. Although, as a law, corrosion does make everything worse.

See the pivot point where the arm lifts up from the glass? Push down in the center there, pull up, push down, pull up. Only takes a few goes and it will always release for me. Leverage is key here and working smart will yield quick and easy results.


Brett, your method was so, so simple, I felt as if I just graduated from the kindergarten...thank you!
