i sent my truck to the chevy mechanics about my 4 wheel drive not engaging and their diagnosis was that i need to replace my front diff vaccum pod and cable and vacuum hoses. would have got them to replace it but it would have costed my $700. so lookin to do it myself but i cant seem where to find them to buy on the internet. any ideas

 

You should be able to get it at any auto parts store like o'reillys, autozone, napa etc.

 

ive tried looking for the front differential vacuum pod in all auto parts online and cant find itt

 

google: jimmy vacuum 4wd actuator
