Bubble under motor mount (9th gen. Gorolla)
Hello all,
I'm lately having some engine vibration at idle. That started after the dealer shop replaced the belt tensioner, which involved lifting the engine a bit. I looked at the passenger side motor mount and underneath it I see a rubber "bubble" that seems to get larger as temperature rises. Is this rubber bulge normal for these mounts or it's an indication of internal failure? I know this motor mount is fluid filled and I don't want to wait till it starts spilling fluid. Thanks. |

The exterior of the mount shouldn't change. Sounds like the internal chamber failed. -- Steve W. |

Sounds like the internal > chamber failed. Life was simpler when they were just chunks of rubber. I couldn't take the metal part off after the rubber was completely gone, so I just slapped the new on on top. Whatever works. -- Cheers, Bev Teamwork: A bunch of people running around doing what I tell them. |

BUT they can be a PIA at times. -- Steve W. |
