Loud vibrating when cold

A lot easier said than done. No buddy, no tools, no time = money to be spent.

that sucks. just make sure if you take it to the dealer, that you ask will this fix my problem before you agree to work. that puts you in the clear if they change the mount and the problem is still there.

on the passenger side mount, you should have about 1/8-1/4 inch of clearance between the rubber mount and the metal bracket on the fender well right beneath the dogbone mount.

It sounds like you have no clearance left, as if it has sunk in, and only when the fluid inside the mount is warmer it dampens the movement. Ericthecarguy on youtube diagnosed a bump noise in the FR of an acura as a broken FR engine mount that caused the engine to literally slam up and down on its mounting.

This isn't a slamming noise. And if it was a blown mount, I would think it would do it all of the time, not just in cold weather when the car is cold, and then not do it when the car is warm or the weather is warm.

But cold can affect a hydraulic mount. The fluid becomes thick in the cold temps, and thus does not have the compliance that it does when it heats up.

But wouldn't it do it all the time, and not just when the clutch is engaged?

What did it end up costing you to fix it? If you don't mind me asking... I just want to be prepared.

How much did it cost to get replaced?

This sounds like the problem my inlaw's 2008 is having.... Any confirmation that the low, loud rumbling sound is a bad engine mount?

Nothing definite yet. Also from what I'm getting, this tends to have only affected 07's and 08's. I can't find anyone anywhere with a 09 or newer that has had this problem.

My car does the samething it sounds like a rattle in my front right fender! I always think somethig is loose or my s2 springs?

09 onwards i think they changed the mount design.

So, I got down and dirty yesterday and determined that it was in fact the main hydraulic mount (right side). I'm gonna switch it out with a new one in the coming week or two and perform an autopsy on the old one to see if I can narrow down a specific failure.

My car started having the same issue this week. I have an 08 Coupe with AT. This was the first week of cold temperatures here for the year, and the noise only happens when the car is first started in the morning and put into reverse (though it actually made noise in park for the first time today). I'm taking it in Monday morning and will make sure they look at the mounts. Hopefully it can be fixed under the powertrain warranty, as I'm at 48k miles and 4.5 years.

So? Did switching the hydraulic mount work?? I'm dying to know... Mine sounds like crap still!!

I'm tempted to simply replace the mount, but I can't see anything physically wrong with it. I hate the vibration and rattle, but I hate wasting money even more...

i changed the mount and all abnormal vibrations and sounds gone - failed hydraulic mount can also be inspected physically through naked eye. you can check its GAP if the gap is low then that shows that your mount is either bad of about to go bad.
