Also, thanks for this information. I had my IDS off last week. I was surprised by the amount of rubber debris in the bowl with less than 10k miles on it. I didn't think that there would be any noticeable wear. The vertical sides of the isolators showed what looked like flaking and some of the side nubs were worn. I didn't think they needed to be replaced yet, but just like tire wear, this is something I'll have to routinely keep an eye on. The procedure on how to do the wear check is a great help. Thanks again.
Thanks Dawg! In the event my rubber isolator need to be replaced, I have an 07. I'm not worried so much about service manual replacement procedures(obviously in the 08 manual), but I would like to know the replacement part number.
