Well, I had a few spare hours and tore out my suspension. This was a virgin activity for me. It wasn't too tough - a track loosening , 4 bolts and a bit of muscle. With the suspension out, it seemend like the ACM mecanism (that little mechanical thingy just behind the rear shock) was getting hung up. After jumping on the suspension a few times, I broke it loose.
As I had mentioned before, the dealer told me that they rarely change the rear OEM shock because it just doesn't go bad like the aftermarket shocks. He told me to check it - if you push it in and it has constsnt resistance, then releases at a constant rate when you let go, it's good. Mine was good.
This was a good time to grease all of the fittings suspension and check the hyfax. I had a dealer replace my hyfax last year so I figured they were still good. However the bottom of the hyfax had big chunks taken out of them (you probably would not see this without pulling the suspension off). What I noticed was that there were a few track clips that were bent up, hence digging into the hyfax. I'll have to straighten these out as well.
Since I have already bought the coil springs, I'll go ahead and change them out. I'm interested to place the new ones next to the old ones to see if there any real deformation with the old springs.
Putting the suspension looks like it will be a bit more difficult. I'm told (again by the dealer) to compress the suspension, then tie it together in the compressed state, then install it. Otherwise, it will get hung up on all of the track lugs, wheels, etc.
I'll let you all know how it goes.
Just another question, though. Now that I'm this far, how difficult would it be to replace the track? It looks like I would have to remove the drive spindle under the engine, inside the tunnel. How do you do this, and how difficult of a task is this?
