Hi guys I am hoping someone can maybe help save face with my girlfriend, her Renault Clio had a broken rear wiper arm and she popped in to the local Renault Dealer who removed the broken plastic part and sold her a new arm.

They could not however remove the metal part that connected the old arm to the car from the rod that comes out from the motor.
They said it would be a workshop job and approx 100 pounds.
Obviously I told her "don't be silly,it's a two minute job, I will sort it for you".

However for the life of me I can't get it off, the final pic shows the new arm with a new version of the offending bolt ready to go on if I can get the old one off. It's not threaded so in theory should just slide off but a pair of pliers and a wrench have not moved it.

Any ideas on how to get it off so I don't lose face with my Girlfriend?
Thanks in advance

I've done this quite a few times. The above tool is no good for this job. It's only good for removing metal wiper blades.

You need to cut the aluminium part as close to the threads as possible with a hacksaw. One split in each side. If you have cut close enough it'll fall off or you will have at least loosened it enough to remove it with pliers.

Two ways IMHO.

A gear puller will work but it will be fiddly.

If it were me I'd get a Dremel tool and carefully carve in two slits as close as you dare go to the main shaft with the splines on.

Did you remove the wiper and be left with this or was it like this anyway?

The wiper cracked in the plastic surrounding the seized bolt so it was slipping up and down, The garage just spread the crack to remove the arm but left the metal bit. They said they can fix it but 100 seems a bit expensive, will try a hacksaw or dremel on thursday and see how I get on.
I did not want to be too heavy handed in case I broke the whole mechanism

I still think the little puller would get a hold of it (depending just how siezed on it is?) or maybe a nut splitter.


Dremel or hacksaw I'd put plenty of rag or whatever around in case you slip!

The problem with the puller is that it is just too weedy. The little feet bend. I've tried before. It's fine for removing unsiezed steel wiper blades but the aluminium bush will be galvanicly bonded to the steel shaft. I think that's the correct term.

Nut splitter looks a good bet, little bit concerned it would crush or damage the 'rod' that the nut is stuck on?

A junior hacksaw will do the trick cut carefully down the side of the shaft (cutting the spacer in two places) once you are near the bottom use a pair of mole grips or similar and it will pull off easily.
You could use a normal hacksaw but you'll have to be careful!

I can confirm that these little pressed steel pullers are no use when a wiper has properly seized onto the spindle, as said the feet just bend. They are fine when the wiper is just a bit tight.

Cutting a slit or two in the metal bushing is.the right way to remove it imo.

Have done this on my Clio - the puller didn't even come close to shifting it, 10 careful mins with a hacksaw and it was gone.

Hacksaw/dremmel/nut splitter, all will work, but as above be very careful & don't forget to cover any paintwork to protect it from hot-metal "sparks" or you will be fighting her when you show her the mess you made of the paint.

As said before a gear puller which albeit extreme is one thing that may work smile.

As E-BMW said I'd definitely shield the glass and bodywork unless you want rust stains. Then again I am told they are popular now biggrin.
