hardenend engine mounts

[SmartGTP]

Well, I sick and tired to replace the engine mounts. Not the ones that we have inserts for, I am talking about the solid blocks that actually supports the engine/transaxle weight to the subframe.

Here is a pic




Since I had my car (1 year), the dealer has replaced this part 4 times!!!!
So, any alternative to the weak OEM part?

If I use the inserts, will these stock parts endure more?

The inserts only reinforce 2 mounts, what about the other 2 on the passenger side?

Dealer response to this frequent replacement....... our shitty roads and bigger tires (235/50/1

Any help?

Re: hardenend engine mounts

what keeps happening to them?

Re: hardenend engine mounts

they become"relaxed"
When that happen, the engine clunks when shifting from drive to reverse or hard accel
Also, feels some clunking (not the I shaft clunk but similar sound) when going up in driveway ramps and such.

Unlikley that the roads/tires are causing it. If you do get the inserts, though, the softer mounts will take the brunt of the vibes/stress unless you can offload it to another area--so they reall will do no good on initial look. You likley would need a harder engine mount, and not the inserts.

So are these mounts solid rubber or are filled with liquid jelly stuff.

I never had one in my hands (all the work have been done at the dealer under warranty) so that why I ask.

That was my first thought.... if I add the inserts, I will be moving the load to the softer part, so will be stressing the mounts more or even worse.... breaking other stuff (like the engine dampener mod catastrophe)

So a complete reinformced set is the only way to go...or lowering the air pressure so the tires can absorb bumps a little more (highly doubt it..who knows!).... I am running at 30 psi right now.

Re: hardenend engine mounts

do you stop before you change gears??????


i have never heard of anyone else having problems with these, so this is quite interesting

[SmartGTP]

Re: hardenend engine mounts

Yep. full stop before going from R to D

Even, after the tranny aplies the gear and I accel hard, like going in reverse up a driveway, it clunks.
If I downshift using the stick, if clunks, slightly, even when the tranny is downshifting in manual mode.

The wierd thing, the mount only last a 4 to 6 weeks tops.
I went to the dealer this past October, they changed driver side strut and mount. The clunking re-appeared like 3 to 4 days ago...
Really dont make any sense at all!!

Re: hardenend engine mounts

did you try changing fuel stations?
add some seafoam to the fuel
or clean air filter


check plugs and change/regap as necessary

Seafoam is a general engine internals cleaner acquired at any auto parts store. Put it into your oil and gas.

I have seen the engine and transmission mounts changed on a 3800 series I and they were solid rubber with an air pocket inside (imagine two rubber "cups" glued together). They were also produced by Borg-Werner if that's any help at all.

Re: hardenend engine mounts

I too am hearing the "clunk" when shifting from Drive to Park or sometimes when accelerating. I took it to the dealership but they couldn't duplicate the problem so I still have the "clunk". Thanks for this thread. I will take my car back to the dealership and have them check these mounts.

tell them to check the engine dampener also, my first clunk was stupid dampener.

Will see if I can find one cheap.... making a polyurethane mold for that part should be easy...
