Michael Gallini:
Hey guys, it’s Michael here at your auto shop in Plano, Texas. Today, we had a customer drop off a vehicle complaining about a vibration felt through the steering wheel while at a stoplight or a stop sign. And upon inspection, we found that the motor mounts were collapsed. I just kind of want to go over and I want to educate you guys on what we see and how we determine that it’s the motor mounts.

Michael Gallini:
As you can see here, we’ve got a new mount and we have an old mount. You can see the difference in the material that’s being shown here versus a difference in the material being shown here. If you flip it over, the way that our technicians are able to identify this is based off of the protrusion of the rubber on the back side of the engine mount. Inside of here is hydraulic fluid. These mounts are hydraulically filled and that’s what applies the dampening ability to the mount.

Michael Gallini:
Why don’t you come over here and let me show you exactly what is involved with having to do motor mounts? When doing motor mounts, the engine has to be supported and not only does the engine have to be supported, but the sub frame has to be lowered to be able to allow the technician the access to be able to remove the motor mounts and put them back in the vehicle.

Michael Gallini:
As you can see right here, there’s one motor mount that goes right here and there is another motor mount that goes over here. You also have a transmission mount. The transmission mounts aren’t necessarily prone to failing. It doesn’t mean that they don’t, but they aren’t as common as what the motor mounts are.
