An engine vibration may be felt after the engine mounts (Fig. 8) were replaced on some 2019-2021 Silverado 1500, Sierra 1500; 2022 Silverado 1500 LTD and Sierra 1500 Limited models. The vibration may be more noticeable at idle.
Fig. 8
The vibration condition may be due to not all necessary parts being replaced when the new engine mounts were installed.
A change was made to some engine mounts and additional parts need to be replaced with the new mounts. If these additional parts are not installed with the new engine mount, the mount will ground out and result in a vibration.
For new engine mounts that require additional parts, the electronic parts catalog will have a note that states “ORDER T/W” along with a list of the additional part numbers that must be replaced with the engine mount. (Fig. 9)

Be sure to review the electronic parts catalog to determine if additional parts are needed before replacing the engine mounts.
Refer to #PIT6036 for more information.

Refer to the EPC for any additional parts needed with a new engine mount. After looking up the engine mount in the EPC, look for the note that states “ORDER T/W” along with a list of the additional part numbers that must be replaced with the engine mount.
What exactly are the other additional parts and where exactly are they placed? There is no reference to this in PIT6036. Thank you in advance, Joe Rizzi.
