I used 3m Window Weld, similar but a little different. I agree about the redesign, I have had so many issues with my motor mounts. If I filled them when I bought the car I think I would have avoided most of my issues.

> Mounting plate above the transmission which holds the transmission to the car mount broke, sheering off a bolt.
> Rubber was torn on Passenger side mount
> Rubber was torn on Driver side mount
> Transmission casing that the bracket for the dogbone mount broke.
> Two bolts fell out of the dog bone mount bracket. (they are 12mm X 1.25 X 90mm by the way)
> The third gets incredibly tight when I try to remove it so I was unable to take it out to figure out the bolt size which made for a simple bolt replacement being an order it, get the wrong part then order the right size process.


What I have done to address this
> 3m Window weld in all 3 mounts, definitely a much better feel, shifter barely moves. Slight increase in NVH, though not much.
> Customized the bracket for the trans mount using a smaller grade 8 bolt, not ideal but car was not driveable, if it breaks again I'll replace that piece.
> Added a smaller triangulated bracket to the trans to dog bone, you can see it in my building a brace brace article.
> Replace the 2 Bolts that fell out

Would you do it with 94A stuff if you were to re-do it? If so, why/why not? I'm deciding whether I wanna buy new mounts or not for this...

I thought about using the polyurethane stuff but the window weld is only $15 from a local autoparts store and I needed it for some hood and roof glueing too. Next time I do it, I'll use the window weld again. I wouldn't mess around with the versions that don't require a caulking gun though as they are too runny. Also leave some air gaps for a little movement to keep noise levels down. If you don't there is still more give than the harder, likely louder, polyurethane.

That said, if you want to make a mold and produce polyurethane inserts to resale then polyurethane is the way to go.

you could try one of these:

even if it doesnt fit, you can cut it down on a lathe. but if its too small.. not much you can do.

Use it where? How? This is not at all close to the current setup.

Are your different than mine? Looks close to being able to press into the passenger side mount. Maybe within 10mm of fitting without pulling the mount.

How about the other two mounts?

So I found this on eBay... I asked him if it's for the manual or automatic, and he said they will fit both transmissions. I'm sure they will bolt in there, but from what I've seen on rockauto.com and gmpartsdirect.com and other places, they are different part number... Any thoughts? http://cgi.ebay.com/ebaymotors/04-08-Ch ... 141wt_1165

Also, which would you use and why, 80A shore hardness or 94A shore hardness and why?

umm... anyone?

I'd like to order the stuff sometime this week, but would like to hear back from you guys first about which hardness polyurethane is better and why... and whether there's a difference in motor mounts between auto and manual in our case.

for he hardness, the harder mounts will vibrate more.

i think the parts of the mounts you are getting is the same, but the brackets that bolt to those are different. but cant say i rely on pictures on the internet posting like actual pictures for verification

found this

good link, that shows the pitch mount and the passenger mount. The ebay link earlier is what my mounts look like. I have a 5sp. I don't know about the AT, I suspect the transmission mount is slightly different, but I don't know how.

Here is the picasa photo gallery link to the driver side. http://picasaweb.google.com/subachad/20 ... ntFilling#

I used the non caulking gun based window weld for this and it just got messy. As I said before the next set of mounts I do, I'll use window weld again, it's a very well spent $15 and a few hours of work.

Mine looks like that too, and the guys I bought it from said it works for both (that link above, got it for best offer of $139+shipping, so 10 bucks off)... we'll see when it arrives. I also ordered some Devcon Flexane 94 Liquid (1 LB) from Amazon... it ran me like $56 with shipping. Will be doing those as soon as all of it arrives. Looking forward to that.
