Motor Mounts

#1

I recently replaced 2 motor mounts in my '98 Corolla. After I replaced the upper passenger side one (under the washer fluid reservoir), I can now feel the engine vibrating a lot. This mount was a delear mount, but the lower one was. Any suggestions?


#2

A new, stiff mount will transmit vibration to the car body.
Has basic tune up stuff been done so the engine idles and runs smoothly?
Have the valves been adjusted?


#3

Might you have over- or under-tightened any of the mounting bolts/nuts?
