I have an 04 corolla and have replaced the rear motor mount going on four times. The last time i replaced all four (front, rear, front right and the trany mount). 2 weeks later and the rear went again and also the front looks pretty weak. Any ideas why they keep going. I did buy the last 4 after market from auto parts warehouse, but the first rear one was from advance auto 3 months ago. It lasted about a month. Appreciate any thoughts on this. tks

Is it manual or automatic? I added Energy Suspension's urethane motor mount inserts to my original front and rear torque position motor mounts, and never had any problems. I found them to be too soft without the inserts, causing them to bottom on harshly and repeatedly when breaking traction.

It's either poor quality mounts or aggressive driving doing it. There really is nothing else it can be.

Aftermarket mounts are never to the quality level of OEM mounts. Master tech is right on the money.

It is an automatic and my wife drives it on a mail route so I would say that's aggressive. When they start to go there is a heck of a vibration of course but even after replaceing there was still a little vibration going on. On those Energy suspensions urethane motor mount inserts. Do you get those online. And would will I need to buy the high dollar mounts from the dealer.tks

 

[hardtopte72]

If you use inserts you can keep your current mount. If you don't the. The dealer mounts will be the next best thing but it sounds like those will wear out too

Inserts are for manual transmission only, not automatic.

It doesn't make sense. Your wife shouldn't be blowing out mounts on an automatic like that. Are you sure the mounts are really failling?

Hey invader. I agree they shouldn't be going like that but there definately ripped apart. Rubber is shot. Do u think something else is could be causing this.

Was the car ever involved in a front end collision?

 

[markjackie]

We did by it with 30,000 miles on so not totally sure but didn't have motor mount problems till she hit 165,000.

Go back with OEM mounts. A little more expensive but hey, they worked for 165K!

 

[markjackie]

When i got them online they said made in china on them, but don't know what brand they were. But the one I got from advance I believe was a beck arnley. I only replaced the rear at that time

 

[invader]

Oh yeah, some Chinese made rubber parts are pretty dang weak... I guess your two other left tranny and upper right mounts are now also of that Chinese make. Maybe you should go with all 4 new Toyota mounts.
