Changed mount,big diff on hard take off'*,but i still get shaking under seat now and then,maybe another mount shakey too..

I have a broken mount in the front of PA. what I am wondering is it best to replace all of them at once.

unless they are bad i would not.

I replaced the front mount in my Bonneville several years ago, and have no issues with the other mounts. Unless you have symptoms of a failed mount, a visual inspection shows issues, or you have extra money, don't change them all.

Ill order the one mount that i can see is bad and put my wood workin stuff away an get this car in the garage out of the weather an see just what i bought.
In my experience, on other cars, when one is bad enough to be torn the rest were not in very good shape either and i have ended up replacing them all. not having worked on a PA 'yet' an I have some fun work comin up that i will need advice on. will start a new thread when i get this up on the jacks an find all that ails it.
I have been tryin to chase down common traits an trends that are PA ways of fallin apart..So just that one motor mount fails and the rest aren't anything to worry about? Im tryin to learn. thanks for teachin an ole fart. spent hours readin past post an will spend weeks more lol

58 bucks and new mount installed,took me 30 min

I have a mount for sale for 30 bucks shipped.. pm if interested

to late now

feels like my rear or right tranny mount is shaking too...

I have the rear, I will send for 20 and it includes shipping. they are not hard to change.. two bolts on top of the steering rack and three on the back of the engine. if you need anything else let me know. i swapped out my 3.8 for a 4.6 and i have the whole engine still. I am going out of town Sunday night for three weeks so just let me know before Sunday.
