Dog bone mount?

[StarLady]

I'm a bit confused with the variety of names used for the engine mounts. I know that my '92 SC has three mounts, and the only one I think I've figured out is the Torque Axis Mount (TAM), also referred to as Top Engine Mount, or just Top Mount. Do I have that right?

Anyway, my mechanic found that the dog bone mount is bad, and I plan to buy it from a Saturn store. He told me to just ask for a "dog bone" mount. I can't find anything called "dog bone mount" on SaturnParts.com...
So my question is: What is the actual name of this mount? I just want to make sure I buy the right part. A part number would also be helpful.

TIA.

Look for Torque Strut Mount. I found it at rockauto.com as this

And TAM (torque axis mount) has 4 components (or in your case 3 components). The top engine mount, the lower engine mount aka dogbone mount aka lower toque strut mount, and the transmission mounts (another dogbone for the top of the transmission and a square looking mount for the bottom of the tranny).

Hope that helps

So TAM (Torque Axis Mount) doesn't equal Top Engine Mount...? From your reply I gather that TAM means the group of 3 mounts (in my '92 SC)?

And "dog bone" mount = Lower Torque Strut Mount = Torque Strut Mount = Lower Engine Mount ?

But you say that there's another "dogbone" mount for the top of the transmission...
How do we know which "dogbone" mount we're talking about?

There are 3 different mounts. But there are 4 mounts total, transmission mount, engine top mount, lower engine dog bone or strut, upper transmission dog bone or strut. Both struts are identical.

In reviewing my service records, a "lower transaxle mount" was replaced four years ago.
Which one is that?

>a "lower transaxle mount"

On the passenger/engine side , the dogbone/strut is the lower mounting.

On the driver/transmission side , the dogbone/strut is the upper mount.

The lower transmission mount is a conventional {neither torque nor strut} mounting (not dogbone/strut).

Yes

See your quote above ^^^^ We know bc there is only one dogbone mount per component of the drivetrain. So when you say Lower dogbone mount or engine dogbone mount, we know it refers to the engine's lower mount since that is the only location where the mount is supporting the engine from the bottom

Now that youve read this far what do you think??

It does not refer to any Torque strut mount dogbone mount, nor does it refer to the Top Engine Mount, so it must be this guy that Richpin shows us how to replace :

Hmmm... Without having watched richpin's video yet, I'll take a wild guess: the Lower Transmission Mount...???

That video shows a Manual Transmission Mount I'm not sure if Automatic Tranny's are the same?...Richpin has some GREAT and helpfull Videos Thanks!

Anyone?

Its the same

[StarLady]

Okay. I watched richpin's video.
It's not a top engine mount, and it's not a dogbone mount. So it has to be a lower transmission mount.

So.... "Lower Transaxle Mount" = "Lower Transmission Mount" Right?

[rc1488]

Correct!!

Saturn has different part numbers for the lower engine mount and the transmission torque strut because the lower engine mount comes with not only the "dogbone" but the engine and frame brackets. The transmission strut comes with just the strut. Prices are appropriately different. It takes two-three times as long to replace just the lower engine strut (dogbone) as it does to R&R the strut AND the brackets, thus the dealer stocks the assembly. I pull the assembly, replace the torque strut on the bench and bolt the assembly back in place. 13mm bolts above the frame rail, 15mm from below.

Thank you, rc, for helping me understand better.

So what my mechanic was talking about when he said "dog bone mount" and sort of pointed to the passenger side of the car, is the "Engine Torque Strut Mount" aka "Lower Engine Mount"
This guy, right?:

actually, it has 4. 2 dogbones (one lower on the passenger side, one upper over the gearbox under the battery), a TAM and the lower gearbox mount. not too many people talk about the last one because it doesn't seem to fail as often as the others...
