Help removing stuck rear wiper arm?

would a wheel puller work?

 

yes, they rent them at autocrats stores. all the best!

have you tried soaking some wd40 overnight?

 

Yup, been there, done that! (…got the T-shirt) I did it with brute force & ignorance, and just at the point where I thought the glass was going to crack , the arm popped off, and all was good! when I re-attatched the arm, I put some anti-seize on the splines to avoid the same thing happening again! To find out why I was removing the arm, you will need to look at the threads (use search) - here's a hint:





BTW "Croil" or "Plus-Gas" can be you friend too!

 

use the handle of screwdriver and tap it off

 

You've got that pic on speed dial .

We us Croil all the time at work for valves.

Croil is the miracle oil.

 

Plus-gas is what I used back in the UK, and when an old friend from Blighty visited a few (at least 20) years ago, she asked me what she could bring me (apart from herself ) which I couldn't get here on this side of ThePond, and I told her I could use some Plus-Gas. It must have been an interesting experience watching her bring it through U.S. Customs! This was long before I found Kroil, and to be honest, I think Kroil to be good, but not quite as good as Plus-Gas! (…but I'm bound to say that! (of course!))

 

There is a mechanic’s tool known as a “steering wheel puller” (or by similar names) which has claws that hook under the edges of whatever you’re trying to pull. The reaction force is directed inline with the central bolt, so no force is exerted on anything other than the stuck parts. Typically there are adjustable or interchangeable tool components to handle different sizes.
