Is there a ''special'' way to remove the rear wiper arm. I've tried to remove it today so i can take the motor off to try and fix it but the arm will not budge off the shaft?

Visit a safari park and let the monkeys take care of it for you? 

New ones are less than £10, you could sacrifice it....

Yeah Thats what i was thinking, Cutting it off..

Try a claw hammer, or pry bar if you have either.

 

A claw hammer has a nice round to the top, allowing a gentle and progressive force, like pulling a nail. Should work.

 

Take the nut off first though,

Thought of the claw hammer idea but nothing to push against under the arm except the rear screen, More chance of the glass going before the wiper arm budges.

Have you tried soaking the shaft with WD40 and leaving it overnight?

Ideally a small puller is required, you screw up some tension and give it a knock to break the hold.

Perhaps you could improvise with some large pipe grips behind the wiper arm and on the end of the shaft, keep the nut on loosely to prevent thread damage.

I wouldn't recommend the leverage ideas, a broken rear window is a problem you don't need.

Good soaking with WD40 and wiper removal tool which pulls wiper body off the shaft without damaging anything. Ive tried other ways in past and invariably something has been damaged as a result. Proper tool and itll be fairly easy. Just remember to give good soak before trying.

I think when I did mine I used a spanner underneath it and kept banging it up and down.

Thanks for replies.going to have another go at it today..

Get a wiper arm removal tool. They cost buttons.

It just screws tight, but you'll hear a bang/pop as the rust gives up and the arm releases. (Obviously make sure you take the nut off first )

Just a quick update, It would not budge so got a wiper arm removal tool from Machine mart.  Took some effort to get it off but yes cheezemonkhai when it did move it came off with a hell of a bang..Stripped the motor down, Cleaned everything, regreased it put it back on the car and it's still not working properly, New motor time i think..

I don't suppose you tried the motor when you had it in bits...

Unlikely to be burned out brushes/windings, the fuse would go first.

Most likely just seized due to rust, if you're keen you could get it moving again or just buy another.

Test the motor works separately and ensure the wiper arm shaft is free to rotate in the housing.

When i had it bits there was no signs of rust or corrosion, Just cleaned everything and put it back together..
