GM Tech (Cam) :

Hello, I'm Cam. Please include all the details about your issue so I can accurately advise you. I cannot see your vehicle so please be detailed.

GM Tech (Cam) :

When did you check the u-joints last?

GM Tech (Cam) :

Does it lack power?

Customer:

its been a year or so since I checked them and the truck has lost some power

GM Tech (Cam) :

Check the fuel filter, cap and rotor first. A misfire can be mistaken for a vibration.

Customer:

it does not vibrate if the truck is in neutral and rev the engine though.

GM Tech (Cam) :

Different load, it takes little to get the engine rpm up in neutral, but in drive pulling the vehicle, things change.
