Default Motor mount question...

Hi guys,
I was just out working on my 06 touring, preparing to replace the fan and I noticed something that, in my experience with other cars seems odd. When I lean on the front of the car, rocking it back while in park, there is probably 2 to 3 inches of "roll" motion with the entire engine. Then when I tried pushing (front to back) on the front of the intake manifold, I got the same degree of motion with very little effort. Does this sound normal? In any other car I've owned, this would have screamed busted motor mount. I can try to get this on video if it turns out not to be an easy answer.

firmly grasp the engine by the intake manifold and try and move it forwards and reverse. if the entire engine assembly rocks more than 1/4 inch your engine mounts are shot and they should all be replaced including the center mount. dont forget to relieve load off the engine by jacking with a block of wood from the oil pan while removing the mounts. remove and inspect all your mounts before ordering replacements. refer to the alldata for correct technical procedures of installation as it has to be done properly. best to remove the front end grille, right wheel, right fender liner, and right headlight for ease of access. also should disconnect A/C lines to access the center mount and loosen the left transmission mount when jacking the engine up. it has to be jacked up enough to get room to replace the center mount. you don't want to be driving on broken mounts as the engine can fall down and hit the CV axles blowing out your rubber seals and then you can't drive it. ask how i know !

Definitely check the upper and especially the lower engine torque struts.

This is what a worn lower torque strut mount looks like:



The good news is that each mount costs only about $10 and takes 20-30 minutes to replace (please be sure to adjust the spacing as shown in the service manual).

The center motor mount is lots of fun to remove (NOT), but you can remove the plug in the wheel well to do a cursory inspection of the mount. This is how mine looked after 8-1/2 years and 100k+ miles. Not bad but since I was replacing the timing belt anyway replacing the center motor mount was only $10 more.

Unhappy Re: Motor mount question...

Just had two motor mounts changed by a shop and they charged me 70 dollars for one and about 80 for the other one. Where do you get them for 10 dollars? PTpreacher

That's your shop providing the parts, and they have to cover their warranty period, that's why you'll almost always pay more for the parts through the shop than what you can get them for yourself.

What brand of torque struts did they install?

I really don't know but, after about a week, I started having a clunking noise from the
right side of the engine. So I took the car back and they said that one of the new mounts
failed and they put another one in for free. ???

The parts should be itemized on your receipt, there is probably a part number or brand name. If just a part number, many times you can Google that and it will come up with the part.

Are there any part numbers on your receipt? If they had to replace one of them after just 1 week, did they install and adjust them per the Service Manual? There is a specific procedure that must followed.

PTPreacher,
Upper

The lower strut is listed just below this. This is for the 09 so make sure you pick the right model year for your car.

$8.48 and $10.49 plus shipping.

As rckstein says, shops charge more because if the part goes bad, they don't get reimbursed by the manufacturer for the additional labor, so that's understandable.

The mount can go bad very quickly if it's not adjusted properly. (The 119mm spacing), but one week sounds really quick.

If the only symptom i noticed was the engine moving while i rocked the car back and forth, i wouldn't even think about replacing anything.

If it made a noticeable symptom driving, such as a clunk when i put it in D,R, or while i shifted.. then I'd replace them. Without symptoms like that, all you'll notice changing them is less money in your wallet and a car that shakes more at idle, imo
