Dogbone Mount - Question

Hey there folks. I'm new to the forum.

I drive a 2005 Ford Focus ZX3, manual trans, mark II. After reading some threads on this forum about vibration in the cabin, they led me to figuring out the dogbone mount on the rear of the engine was bad. I went to the nearest Ford dealership and purchased the mount. So thanks to the community here for helping me find that. I plan to change the it this weekend.

I've changed engine mounts on past cars I've owned, but never one that looked like this. Do you have to use a torque wrench to tighten down the bolts once replaced, and does any know the amount of pounds/force to use? Or will hand tightening with the just simply the ratchet suffice?

Much obliged!

Super easy just make sure u put the transmission bolt I'm first and then slide the other end into the subframe portion. If I remember right I torqued em down to 66 foot pounds.

66 foot pounds? That sounds like a lot. Are you sure it's not somewhere around 35 ft pounds for the roll restrictor?

Just get 'em tight, I've never used a torque wrench there. That doesn't mean tight like a girl (no insult there!) though.

I found a thread on the forum here that said torque the bolts to 35 lbs, so that's what I ended up doing. The bolt on the top of the mount bracket was really tough to tighten down, so I hope that one if ok. I tightened with the 13mm gearwrench with the hand, but it was really tough to get some leverage. I'm HOPING that bolt holds.

I was able to get the bolts off without any big issues. I really had to get some leverage on the one tied to the frame, and still ended with bruised knuckles.

Ford has redesigned the dogbone mount, so I had to drive to 2 different dealerships, neither of which were in town, to find the correct mounting bracket. The original parts dealer at Ford failed to tell me this would be needed.

In the end, a 45 minute project turned in to over 3 hours, due to all the running around.

Ive not heard of this one being that tough to remove before...i mean it wouldnt be surprising if you lived in the snow/rust belt but not on a southern car.

Do you now anyone with an impact wrench?

I think the shop that put my clutch in may have torqued this bolt down a little too much. I just don't want to strip the head

Could try heating the bolt with a torch as well as tapping it to knock lose some rust. If all else fails you could weld on a nut and try again if you strip it.
