How do I remove wiper arms?

[jims-terrano]

I have the normal water ingress from above heater assy on the NS. It's proven ingress and not matrix. So wiper arms need to come off but I can't seem to pull them off the spline. I've left them soaking in plus gas but they seem stuck solid. There doesn't seem to be anywhere to prize with a screw driver either. I'm sure others have done this fix so must have come across the same problem. I'm guessing some kind of small hub puller would do it but I don't have anything like that.

The way I do it, is to undo the nut until it is just above the thread, lift the arm up, taking up the slack, then a sharp tap or two with a hammer. Keeping the nut on, stops damage to the thread when you hit it.

I have found that some times when very bad, an open ended spanner, slipped under the arm, with a bit of cloth under it works.

Tapping with a hammer does that not risk damaging the wiper pivot tho?

Just been having ago with the hammer all be it small hammer. Tried top of the pivot, tried side of wiper arm and also on the side of the nut but it refuses to budge.

They come of easy undo the bolt pivot the wiper back sharp yank side to side will come off without any penetrating oil as they are on tapered spline

The actual spigot is tapered, so the downward force of the hammer blow is what breaks the adhesion. That is why you lift the arm part up, so you are not actually putting any load on the mechanism underneath. If hitting the nut is not shifting it, then you may need to get a puller, as it is on there hard.

Take the nut off, thoroughly soak the thread in penetrating spray, so it runs down the threaded shaft onto the taper, put the nut on loosely, and if it is raining where you are, switch the wipers on for a few mins, the movement will help it work in, or leave it over night to soak in..

It won't wiggle by hand, it doesn't seem to want to budge with more tapping. Squirted more plus gas on them and left them again. This is what happens when I touch cars and I lose interest :doh

Dont tap it it will break did you pivort the arm 90 degrees from the window it should stay there

When I did mine, I used a small pry bar, a towel and a small piece of wood. Lay the towel to protect the paint, then put the wood near the wiper spindle and gently pry and wiggle, as already stated, keep the nut on the end.

I you use my method to hammers or prybars required :thumb2

But I have a complete range of pry bars and just had to use one on something :lol

I made a puller, looks like a "G" clamp.
Fork on the bottom that goes under the arm, then a nut and bolt on the top that presses on the shaft.

Made from an off cut of galvanised strip, like used to hold roof trusses to the wall.

Works a treat, no strain on anything.:thumb2

Takes less than 10 minutes to knock up, if you have a vice to hammer right angles from the strip.

This is so easy, I have removed hundreds and never had a problem, remove the nut, swing arm out so it is pointing forward, now rock towards windscreen then to bonnet, two or three times at most to remove, you have the advantage of heaps of leverage, Rick

Haha got the arms off at last thanks to big bunny, cheers Craig and they were stuck on. They'll be getting a smear of grease when they go back on again.
