I have a 2005 Nissan Frontier Nismo with 70,000 miles on it.  A while ago my low pressure signal went off.  When I got home I tried to remove the metal valve caps and they were frozen on.. I had to use plier to remove them and basically 'tore' then off.  I checked the pressure and one tire was low and I put air in them.  I never replaced the caps. Today I went to have 4 new tires put on and the tire dealer said they could not remove the valve stems to let the air out of the tires because they were galded on (I think that was the word he used) and they had to let the air out of the tires manually (pushing in on the valve stem tip).  The question I have and I don't know if anyone has the answer, are these just normal valve stems or special ones.  I was thinking of spraying them with WD 40 and trying to remove them and replacing them with new ones.

Thanks,

Bruce
