Freeing up Rear Adjusters
 

Just got back from the dealer after trying to get an alignment done.
They told me that they couldn't do the alignment because the rear
adjusters are frozen. This is the second time this has happened. These
adjusters were replaced 4 years ago. The question I have is, has anyone
had any luck freeing these up by use some kind of penetrating oil or by
heating them up?

Thanks
