Hello does anyone know how to remove the rear wiper arm?

Hi I have a 2009 SLT2 (I guess is two its fully equipped)..


anyway I just noticed a few weeks after taking her in for an oil change that my rear wiper arm has broken off at the a hinge.

So I ordered the arm and wiper.. I then removed the nut from in front of the arm but for the life of my cannot remove the old arm..!!

it seems as if its fused to the actual bolt..-when I move he arm the bolt is on moves.

I've applied Wd-40 to try and loosen it up, and looking at the replacement part, the slot where the arm attached to the bolt is just a smooth metal cylinder.

I'll probably have to take it back to the dealership to remove the old one and put the new one on.. but I would like to do it myself

any ideas?

Bite the bullet and take it to someone with the proper tools! If you're not real careful, you could risk breaking the back glass. It'll be worth the $ to have it done.

Re: Hello does anyone know how to remove the rear wiper arm?

If you bought new, take it back to the dealer and ask your sales person for some help in working with the service mgr to see how can be done under warranty if you are under 36,000. Maybe can write up as faulty hinge pin from factory? Anythings worth a try. If sales person has been with the dealer any length of time, they sometimes can do wonders, or have it done at cost. Worked for me in past with Ford 3-1/2 years ago. Don't ask, you won't ever know.

Re: Hello does anyone know how to remove the rear wiper arm?

The same problem was experienced with my SLT2. The wiper arm hinge broke when it was lifted about half an inch to clean the window. It was very cold and the hinge snapped.
I called the dealer who did not have the part in stock but receved it overnite and it was replaced on warranty the next day. I was on vacation in Maine and had no connection with this dealer, a very pleasant experience. I watched the repair and they simply used a "gear puller" to remove the arm from the shaft, a two second operation.

Take it to the Dealer. We had the dealer replace our back wiper and they BROKE it themselves. At least they repaired it. I could not figure out how to remove it myself. At least when they break it, they fix it at no additional cost to you.

[size=10pt]I tried pulling back on the wiper arm when I was wiping the glass after a wash and It felt like it would not bend at the hinge more than an inch.

Is this the case...the arm is not designed to move but far enough to wipe between the arm and the glass ??

Thanks, [/color]

Yes this is the case. The wiper blade arm does not lift more than about one inch before breaking, especially if it is cold.
The blade arm can be removed easily with a small gear puller.

Re: Hello does anyone know how to remove the rear wiper arm?

Yes. I had a problem with my 2009 rear wiper arm getting broken and had to remove it. This is how you fix it -

Use a gear puller and it will pull the old wiper arm base off of the stud bolt easily. A gear puller has two adjustable arms and a center threaded screw. Remove the nut from the stud that holds the wiper arm on using a 1/2" end wrench. Once that is done, get the gear puller. You cannot pry the wiper blad base off of the stud bolt without a gear puller or without breaking something else. Put the gear puller arms on the plastic hub around the stud bolt, tighten the screw on center of the gear puller until the old wiper base pulls free. It will pop right off. Once that is done, undo the rubber hose from the grommet (pull it out of the rubber grommet that it's in) and remove the old base.

Put the new rubber wiper blade on the new arm before you try to reinstall the new arm. The new wiper blade (that must be purchase separately) snaps in to place on the new wiper arm. Use Channel Locks to snap it in to place as it takes a lot of force. Once you snap it in to place, it will stay there permanently. Now place the new wiper arm base on the threaded wiper stud, set the level of the wiper parallel with the bottom of the window, and screw the nut back in to place using the 1/2" end wrench and tighten until snug. Route the hose around the bottom of the assembly and push it firmly in to the grommet to seal it up. Snap the wiper arm base cover back in to place over the nut making sure not to pinch the hose, and you're done. This whole replacement with the correct tools will take less than 15 minutes.
