Motor mounts stock ls
 

Well I think it time to change my motor mount getting a vibration thur the steering wheel at a idol .. So what is a good stock motor mount to replace it? Cost wise ? Well my baby hit 200.000 miles and still starts on a dime .. It is a stock 2.2 engine:twothumbs:

You also have 2 tranny mounts. Shopping around can be useful.

Turbo tech racing has fancy poly mounts, Dorman and GM have the stock rubber mounts, check good EBay Prime Choice , A1Auto come to mind

The vibration you feel may or may not be from the mounts.
With that many miles you should also check the steering column components for wear.
