Hi there,
I'm replacing my lower ball joints and I'm having trouble removing the Auto free hub cap. It seems to me that it's threaded on considering it's knurled on the outside diameter. I tried removing it with a pair of of pliers both ways in case it was a left hand thread but it's not budging, I didn't want to start applying excessive force on it because it's 25 year old plastic. Anyone run into the same problem?

Sorry guys. I just realized the cap was aluminum so i put a little bit of heat to it and I got it off.

Yup, they get stuck after a few years. An oil filter wrench with a strip of rubber to protect the chrome sometimes works too.

Greatn idea. Thank you.
