Thumbs up

Hi,

What is involved with replacing the #3 engine mount (rear, dogbone)? Would i have to have the engine still elevated and if so would I even need that much push from the bottom? The rubber around the frame side of the mount is about rotted out. Thanks in advance.

No worries. They don't support the engine against gravity -- that's the role of the engine and transmission mounts underneath. The dogbone simply prevents rotation of the engine forward/backward when going into gear or hitting the gas.

Excellent, I was gonna go to autozone and pick one up for this afternoon. I'll keep monitoring any more answers until then. Thanks for the advice.

I just read your post again. If you mean the true dogbone on top of the engine, my earlier reply is right.

If you mean the mount at the base of the engine/transmission at the back, yes, you DO have to support the drivetrain.

The dogbone I've outlined in red below is the one that is not holding the engine up -- only keeping the top of the engine from rotating toward and away from you.

FWIW, they call that one the engine roll restrictor.

I have a tendancy to wear my mind on my sleeve. I have a history of losing my shirt.

Strange that it has so many terms. I've heard it be refered to as the "torque strut" as well.

I am working on a similar issue. But my car does not have the roll restrictor pictured above installed. is there an alternate location or a different configuration maybe?

Pretty sure that's where it is. I don't think it was standard until 2004, maybe 2003, which is a mystery, because Ford was heavily de-contenting the car at that point. Maybe they sprung for the expense to prevent warranty costs around the engine and tranny mounts, which take a real beating without the dogbone.

If you have the mounting holes in the strut tower, putting the dogbone on is no big deal. I think. Maybe. Get the bracket at a boneyard.
