k, in the middle of the install...

I got the stock mount out in ONE PIECE!! still able to be reinstalled and used at a later date, if needed/wanted.



dunno if I'd be able to get it in again, but I got it out as one piece -

I put a big screwdriver in around the sides, lubed it up with WD40, then instead of trying to push it out the other side, I lifted the screwdriver up and pried it out towards the same side the screwdriver was on... took me 5 minutes... WOOHOO!!!


ok, back to the new install, gotta go... talk to ya later...

WOOHOOOOOOOO!!!!


EDIT: oh, and... I didn't even remove the bracket from the front radiator support... all I did was take out the dog bone...

With the 3800 performance mount I've noticed the shudder I experience is only if the car is coasting down and in overdrive like coming up to a stop sign or slowing down. If I manually shift the car into 3 (drive) while coasting the shudder goes away. Could the shudder I feel be something wrong with my transmission, or is this what I should expect?

k... just took a quick ride.. and I mean quick... only about 5 minutes.. cuz the wife is home from work... so time to make some dinner and chill...

anyway... just walked in from doing a test ride with the new motor mount... AWESOME!!

in the brief 5 minutes I had... yes, you can feel the vibration in the steering wheel at idle... but while driving, I didn't notice anything... except quicker accleration and harder pull when romping on the gas... was SUUUUHHH--WEEEETTT!!!

definitely an improvement, even over the stock flipped mount...

06MonteSS

just took a longer ride, and a blast on the highway... didn't notice any shuddering... but on the highway, when I kicked it down to take off, didn't seem like it pulled as much as with the flipped stocker... interesting... Hmmm...

normal around town driving definitely pulls harder/quicker, can feel a difference...

Far as the shudder goes. Try and loosen the bolt a little, I just tried that yestarday and it seemed to reduce it even more. I wish I could find the factory torque specs for the motor mount. I think that's why people are getting shudder is the bolts to tight?

supercatxr7

I've asked on multiple boards for the torque setting, but no replies. Doesn't anybody work at a dealership and can check?

06MonteSS

yeah, I'd like to know how much to tighten it as well.. I have the dogbone arms right up against the sides of the mount, but I could still tighten it even more if I crank it... but afraid I would bend that metal tube that goes through it... if I didn't already LOL

06MonteSS

no one knows how tight to make these?? if there's no hard numbers out there, how tight did you all make yours?? crank it down til it wouldn't go any further?? backed off a little from that point?? etc etc...

scarlett

Well when I first put my ZZP one on I cranked it down hard. Found it was to tight so I have it like maybe 1-2 turns after snug factory it was easy as hell to take off.

To bring this issue back up, I've noticed exactly the same shudder as described above, and I agree, that it seems to be tied to the trans being in OD. There must be something to this. Anyone else able to concur that shifting out of OD eliminates the shudder?

I don't get a shudder anymore, in any gear. But its always hot around here and the mount is flexy all the time.....I haven't seen anything as of gear selection though, thats interesting.

supercatxr7 and i split a pair of the msp ones, very nice motor mount indeed and very mild vibration sometimes when slowing in 3rd and 4th gear....downshift and its gravy

Hey guys, i have read this forum everyday for a year since i bought my 07 MCSS a year ago. I never really needed to reply because everything i wanted to know was answered, but i am having a horrible shudder at 55-69 mph. I took it back to dealer 3 times. 1st time they said it was 2 tires unable to be balanced because error in side wall crap. two new tires and still annyoing shudder on highway, 2nd time did nothing, 3rd time i took it to another dealer i know, they told me it is the tourque converter locking up on highway and that is what is causing the whole car to shake and shudder in the sterring wheel. DO any of you guys get this and do you think this is related to the motor mounts? Weird thing is it smooths out after 70mph and in that sweet zone of 55-69 when gas is pressed or when in 8 cyl mode it really shudders vs. in 4 cyl or when it is costing. I was going to go to local tire shop to see if the tires need balanced or if the new ones have any errors in construction in them, but i think there is something more.

Yeah, sounds like it could be a mount or tranny issue. An unbalanced tire shouldn't balance itself out at that speed (70+).

From what I have found out, somehow it is related to the car being in Overdrive and also the DOD. When I put a tune in my car that disables DOD, the shudder on slow down/coasting goes away. When I put a DOD tune in the car, the shudder comes back. To me it seems to be a problem with the DOD function. If on a coast down in OD the DOD were to turn off at around 35mph, there would be no shudder. Unfortunately it does not snap out of DOD mode or downshift until around 15mph or so and this causes the shudder. It is not a problem of the mount.

Thanks Supercatxr7. I think I'll fish around the dealer to see if they have any reports or history on this.

Let us know what you find out. I need to do something about it too.

just wanted to ask a noob question about changing the mount. Since there is only one upper mount, isn't it possible for the engine to shift after the stock one is removed? does the engine need to be supported in any way while installing the new mount?

Corny40

iTrader: (7)

No, it does not. When you remove the "dogbone" the engine will be able to move a little, but you don't have to worry about it falling or anything, or anything even close to that happening. It's a very safe and easy procedure.

I see you are Diablo tuned...You sure this isn't the notoriously annoying DOD "surge" that everyone complained about? Do you get it when you revert to the OEM backup tune?
