They should be able to diagnose broken engine mounts by putting it drive or reverse, holding the brake, and revving the engine while observing if the engine lifts off the mount. And yes use the H3 mounts if they need replacing.Dropping off the Tahoe on Friday.
I'm going to have the shop look over everything...all the bushings, rear arms, panhard bar etc...
As for the engine mounts, are they able to diagnose if they are bad by just putting it on a lift? What's the best way to find out if they are done?
I've read that everyone is going with the Hummer Engine mounts instead of the OEM Tahoe ones. Is that route I should go if they are done?
Thanks guys in advance for all your help
