Yeah dojaman I remember seeing this DIY posted in the SRT forums. It was posted back in '05. Good stuff!Filling the stock mounts is a pretty straight forward job. The biggest problem I had was figuring out what to fill them with. I did some searching and found this stuff, this is the real deal. You can get it at Grainger, it's $35 for a pound. It will fill all 3 mounts and you'll have some left over.
Devcon Flexane 94a:
The first step is masking off the mounts. This is a critical part because you don't want the flexane pouring out everyhwere or else you'll be dishing out another 35 bones. I taped it off with duct tape and it worked fine. Note: I cut off the rubber stubs on one side of the tranny mount because it made it much easier to mask off the mount. Also, which ever side you mask off will have the print of the duct tape, so if you care about how the top mount looks make sure you mask the BACK of the mount. Other than that I didn't have any trouble masking them off, just make sure to tape it up good!
Next you have to mix the Flexane. There's instructions on the box and it's pretty easy to understand. Once mixed you'll have about 20 minutes before it's begins to harden. You don't have to hurry up but be aware that you won't have all day to play with it. Once mixed it'll have the consistency of motor oil.
Pour the urethane in to the mounts:
And that's that! The full cure time is 7 days or you can heat them at 100 degrees for 24 hours(All this info is on the box) Once fully cured these suckers are stiff! I only installed the tranny mount and I can already tell a big difference in stiffness and vibration.
Are you doing this with ESC ON..? I think you would rather want to try with ESC off...Is anyone else havig issues with wheel hop when you are burnig the tires out of first gear? Mine did the other day ad it sounded horrible! Is there any quality bushing kits available to stop this?
