If you have new motor mounts, why do you think they need to be changed?
If you have OLD motor mounts, again - why do you think they need to be changed?

Pittdawg said:I told my mechanic to rev the engine while I watched with the hood open. The whole driver's side portion of the engine lifted up at least 2 feet. I knew I had at least one collapsed motor mount at that point. Simple but works.

JEvans said:Ok, I am getting a noticable vibration on my '02 LTZ & have been told by my chevy Vette shop manager, that the engine mounts should be replaced, that unless they are split or broken, i have some time to save up for the repair bill. He seemed to think they are not vital at this time. I did the same test as Pittdawg describes above, & the engine did not jump out of the engine bay of my Trailblazer. I am inclined to believe that the new serpentine belt is very taught & may cause some of the vibes ! I agree with Roadie on this one !

and i think that might be just the price for one not a pair. bt don't hold me to that
I visit Korea 3-4 times a year. It is in no way a third world place. Seoul is indistinguishable from NYC or London. The proof is that THEY outsource jobs to China and other lower-cost countries.Dillyo82 said:Just was questioning From Korea.
the roadie said:My worry was the bolts to the engine look accessible, but I had little confidence they would come out as easy as the ones on the mounts themselves. The factory shop manual describes your procedure, so it's not an unreasonable idea.

That is totally true.SBUBandit said:Seems like i read on the OS that motor mounts seem to be the one thing on these trucks where it is a very good idea to stick with OEM. Seems like people had some sort of issue with aftermarket mounts.

Mooseman said:I replied in the manuals thread. The procedure for the mounts is in the 2008 manual.

Probably my over sensitive Norton.
Heck, half the dealers don't know the connection between vibration in DRIVE and a collapsed motor mount. I've read of dozens of misdiagnoses (all paid for by the owner) including changing throttle bodies, plug coils, etc. I didn't believe it for months and I had the syndrome!bugeyed said:... It doesn't mention the 10Hz vibration at all. ...

Does anyone see any benefit to removing motor mount brackets, upper or lower, to facilitate motor mount replacement?
In order to replace the motor mount? I have read that one member removed his top bracket because it was cracked & proceeded to do the same on the other side. It allowed him to not have to lift the motor as much to get the mounts in. I am proposing to remove the lower brackets, as the bolts are easily accessible. Seems like after removing the top nut, lifting the engine slightly & removing the lower bracket with the motor mount. Install the new mount on the lower bracket & reinstalling the assy., lowering the engine & installing the top nut.
The advantages, as I see it, are;
Minimal lifting of the engine.
Most of the work done from the side (bracket bolts) & from above (top nut).
One concern is whether there's enough room to get the lower bracket, with motor mount attached, out of there.
Any comments are welcome.
Thanks,
kev

I am going to make the tool that I got work to remove the Fan. It is a regular thread that loosens to the Left correct?
Any Penetrating oil, Heat, other Tricks to get it off. It's stuck on pretty good. Got two bolts to hold the Pulley and tried smacking it with a Hammer, but it didn't budge.
