Front wiper arm

Ok the end piece of the wiper arm has come loose and is very noisy when wiping my question is can it be fixed or does the whole arm need replacing as I can only see these for sale pic included

 

Morning

You can buy an arm and blade for little money, it's hardly worth trying to fix such a thing, unless it's just the wiper blade that's broken. Pictures speak a thousand words

Just realised that's an image of a rear wiper!

Hi lol yes just used that to illustrate the part that’s broke
I will take a pic and upload later

 

This is a pic of the actual wiper

 

Is the wiper noisy in only one working direction?

 

Yes it pops back in but doesn’t stay and is quite noisy

 

In this case the wiper arm must be twisted to place the wiper upright on glass.

 

Ok will give that a go
