Hey I'm having a technical issue trying to get the knuckle joints fitted to the top arm. I have the arms out on the table, and I pressed in the cups. I understand that the cups act as a lip for the boot to catch on. 

 

But my issue is that I cannot get the joints pressed in, there is no space when the cup is in there. I tried a heat gun to soften the plastic, but that had no effect. Am I missing something obvious here?

 

I bought these knuckles

You’re trying with two cups …

Remove the cup from the joint or remove the one you have in the top arm.

As above take out the part that is already fitted.

 

maybe get a workshop manual as well.

it may not be immediately obvious, new knuckles come with one pre-fitted.  the replacement cups are if you want to keep the old knuckle

 

I'll be honest I nearly did exactly the same, ordered new knuckles and new cups, then realised when checking fitment

Well you are totally right, The kit came with spare cups, so I assumed incorrectly they were needed. Appreciate this thank you.
