My front passenger side was squeaking very loud. I place a floor jack underneath the LCA to discover that it was the lower part of the coil over. I sprayed some Tri-Flow and the squeak went a way for a while. After doing a lot of reading I narrowed it down to a worn out heim. The teflon in the heim breaks down and if you don't replace it soon enough it will wear through the body of the coil over. When doing the research I found very few pictures but nothing in detail. Below are the steps I took.
The first step is to remove the spacers. I placed a small flat head screwdriver in the middle of the spacer and hammered it out. You can do this with both sides. You need to pay attention to the long spacer and the short spacer. You can see that I labeled my coil over "L" and "S" for long and short.
Hammering the spacer out
When you first remove the spacers it's hard to find the retaining clip. The tip of my screwdriver is touching the tip of the retaining clip. I used a small pair of needle nose to remove the clip.
Removing the retaining clip can be a pain in the ass. You can see in this picture the clip is removed and you can see the slot where it was placed. Please note that these newer SAW's only have one clip on each coil over.
The other side does not have a retaining clip. The body of the coil over has a stopper built in. From that non retaining clip side I used a 9/16" socket and placed it on the heim and hammered it until it got loose. I was patient even though it was barely moving. I finally gave it one good smash and it came out.
This is the teflon that just fell out when I took out the heim.
When you install the retaining clip you have to feed it in the slot so in this picture I was practicing before I installed the heim.
Installing the new heim. I read many different articles where guys would freeze the heim making it easier to install. I let it sit in the freezer for about 10 minutes but most guys let it sit 20 mins.
I used a socket that fit on the edges of the heim but not touching the center part and hammered it in.
The heim fully inserted with the slot for the retaining clip showing.
The heim fully inserted from the other side pressed up against the stopper.

When ordering parts for the 2.0 or 2.5 make sure you order the COM-10T which is the 5/8" heim bearing. The older SAW's use smaller heims and clips that don't fit.
