I replaced the motor mounts on my trailblazer by myself in like 30 minutes. It's not that hard to do stuff like that.

You may be ok if the bushings are breaking down. I'd honestly be surprised if they are.

ETA... I just looked at what the motor mounts look like for that vehicle. 3 are the "can" type mount and their failure will be obvious because your vehicle will idle rough. The last mount is just a stabilizer and carries no weight. You can change that easy, or ignore UT


Get a pic if how bad they are. That will tell us more.

As a check of the motor mount. Park your vehicle, pop the hood and get someone to rev the motor while in park. Do you see excessive movement? If not, don't worry about it.

If it's making a bad clank noise when you go over bumps, it's your "stabillizing" links on your sway bar. You don't have to change those either...

Eitek1, this is helpful. When you say "excessive movement" when you rev the motor, what sort of movement am I looking for?

If it's a transverse mount motor it will make a clunk when you shift into drive from reverse. Usually the top dogbone mount fails over time.
