Hi,

My car shakes when in park.

The engine mount was replaced a few weeks ago and I had a alignment several months ago.

Thank you,
R

Good morning,

There are a total of 4 mounts for the powertrain. I posted the mounts below for your review.

Which mount did they replace? The upper engine struts were the most common failures for the big movement of the engine while running.

Are you sure it is a mount issue and not the engine running rough making you think it is a mount?

The other mounts I listed need to be checked for being broken or worn out.

Hi Roy,

I was advised that the other mounts were checked and were okay.

But they put an aftermarket part when they replaced the lower engine mount that was worn.

I think putting an aftermarket part instead of the original part would make a difference.

What is your opinion?

That is correct. The aftermarkets one are not the same. That is why they are double the price.

I think one or more of the others are worn as well. Ask them to recheck them.
