Has anyone had experience installing the isolation plate to fix the known torsion bar problem. I have read instructions for using silicone spray to temporarily alleviate the squeak but crawling under the car every few weeks is not a great prospect.

Here is a link to what I'm referring to

Specifically I'm looking for parts number and instructions if available. any help is appreciated. Since my car is out of warranty I will try to tackle this problem myself first.

The darn thing is getting louder and basically creaks or clunks all the time. It's embarassing.
