    Default Do I have a bad engine mount on my C1500

    I have a 1995 Chevy C1500 with a 4.3L engine and a manual 5spd. transmission. Recently I noticed one day that when I was in either 1st or 2nd gear and I really got on the gas or did a fast start my shift lever would kinda rock a bit to the right with the RPMs. Sometimes I can hear a small like knocking sound when I do a fast or hard start in 1st gear when I left off the gas to make a shift. I checked the rear transmission mount and its good and tight. I didn't really check the engine mounts because they are hidden behind the exhaust manifolds. From what I can see the engine is sitting correctly and not sagging to one side. When I hear the knocking sound it seems to be coming from the driver side so it seems like mabye the driver side engine mount is bad.Any ideas? Also if it is bad how hard would it be to replace.Thanks for your help all!

    I kinda doubt it is the engine mount, since the motor would rock alot harder and some torque to the right is normal. If it is bad, they arent that bad you will want an engine lift.
    I would actually look at the U-joints but i dont know exactly what kind of knocking you are talking about since i cant hear it sadly.

    Seems if you had a bad mount would be on passenger side.. due to torque of engine.
    Only way to see it have someone to set parking brake ..hold main brake put in gear .
    Crank truck ..put in gear ..give it some gas see if engine lifts up off of mount.
    While standing beside truck.. not in front might get run over if brakes messed up .
