I need to replace my vacuum actuater on my '97 blazer 4x4 (the one that switches from 2wd to 4wd). Anyone have pics, or give me a walk through fr replacing it?


TIA

and they quit working after a year or so. he put in one of those posi lock deals instead and hasnt had any problems since. its about $150
