aluminum diff & subframe mounts?

[Streamln1]

Did you do anything as far as adhesive to hold the poly in place so the diff doesn't shift from side to side?

There is no place for any of the poly to slide. It pressed in tight and even if it could there would me no room for it to slide. Once you look at your subframe you will know what I mean.

There is actually about 3/8 difference between the bracket and the mounts width, the sleeve the bushing mounts into could potentially slip either way under extreme circumstances, even though the poly itself may not move the sleeve could. Its a problem I have been trying to prevent in my build, I have pretty much the same thing

I made it so that the poly that presses in for my diff mounts sticks out a little bit on each side of the mount. It's not the full width of the dowel pin, but it's wider than the stock mount. So my 3/8 difference is more like 1/8. I had to wiggle the brackets back in between the ears when installing them because they were snug. You can see here that the poly is slightly taller then the hole it was being pressed into.

My old roomate had aluminum diff bushings and his dsm and it transferred a ton of noise through his car. That's why I made poly ones. Last picture is actually a video I made showing how much play each brand new stock bushing has. I have enough material left to make another set if you want to try this on your own I did this a few weeks ago but haven't got to try it out yet. I'm still waiting for GZP to ship my poly control arm bushings.

nice job the video was pretty cool to i didn't realize how bad the oem bushings were lol

Mine are the same way, the point I was trying to make is that even though the poly and the dowel may stay in place in the bracket, the eye itself that the bushing is pressed into could potentially slide on the poly itself, all 4 mounts face the same way so it could do so if its under enough force. It took a good bit of force to get my poly in too, but not as much force as there is going be placed on it while driving.
