One thing I wanted to try after getting the idea from Caden Leinen, was to stiffen up the other motor mounts a bit more. Tony DiCunzolo offers the lower transmission mounts and they make a huge difference. With that, I always wondered if there was an option for any of the other mounts. Caden introduced the idea of using some liquid urethane to pour into the existing mounts in an attempt to stiffen them up. So I ordered a new upper transmission mount, and while I was at it, some new lower control arm bushing housings. The passenger side motor mount can’t really be filled with anything as it is pretty sealed up/encased and there is no easy access to the internal damper. I will be using some 94A liquid urethane to stiffen these parts up. I’m sure I’ll introduce a ton of NVH, but…you gotta pay to play.

Here is the newer, updated transmission mount. It’s very different than the original one. The original one had a history of breaking down and becoming a problem. The updated version is liquid-filled as well.

I began by removing the 2 bolts holding the assembly together. The problem is, the bolts are a 5-sided design (sometimes called pentabolts) instead of the traditional 6 (or 12) sided ones. In order to get these off, I needed the sockets to fit it. I tried using a few other type of sockets to “make it work”, but they all just started rounding out the pentabolt.

I got the socket set from Amazon. It was only $40, so it wasn’t too bad. Who knows when I’ll need it again, but since I’m a tool guy, I’ll just add it to my collection, LOL.

This one took the size 14 socket
Pentabolts removed.
