Ranger pvh vacuum loss
1999 ranger , 150 000 kms... I have had problems with the PVH hubs disengaging... its been a long process but Ive narrowed it down to a vacuum loss to the hubs... I have steady vacuum supply to the solenoid thingy under the wheelwell and when I take the vacuum line off from the output of the solenoid thingy I have steady vacuum for about 15 seconds then....nothing.... My question is ... what tells the solenoid thingy to pulse...is there a module somewhere?... I know the PVH hubs are not the greatest but mine work great when they are engaged... they are just losing vacuum...and disengaging?...PLEASE HELP... if this is answered quickly I willl definitely donate :)

Not to say this is your silver bullet, but 3 times I had the same problem. The metal vacuum tubes at the wheels corrode. pull off the rubber vacuum tube from the metal one, clean it, and very lightly put a touch of silicone gasket maker thinly around the tube keeping at least 1/4" from the end of the metal tube and re-insert the rubber tube back on. Then try it.
