WTF..  out riding today.  Normal riding, nothing crazy and the passenger rear shock blew apart.  The same thing happened to the driver side rear shock earlier this year.  Same exact thing.  The shaft pulled out of the bottom connector.  Called dealer, it is covered, but he said out of the 60+ units he sold this year, I was the only one having problems with shocks.  I would hate to see if I was out beating it and going off jumps and stuff. When this shock popped, it took out the rear brake line and it was rubbing against the inside of the rim.  Had to limp it back to the parking area, maybe 1/4 mile.

Doesn't look like it was threaded more then three threads in.

Was reading that your front shocks came loose, were they leaking fluid? how did you notice they came loose?  So maybe mine came loose and pulled the last 3 threads.  Not sure.  Going to pull all of the shocks and back them out a thread or 2 and add some red locktite.

I think it's a good idea we all take a look at ours and if you see any threads showing, better check it out. These guys seem to have a problem with leaving things loose or not correctly torqued. A-arms, motor mounts, diff mounts, steering parts, body bolts/screws and now shock assembly components.

Yep. Looks like it un threaded. That what my front passenger side did. Winched it up a tree and put it back together. Still gotta call the dealer as the valve pin came out and bent plus dumped all the shock oil

Have any of you noticed the shock rubs on the spring, to the point where it's taken off paint. I'm wondering if that could have contributed to the problem. Or is it just me who has that problem?

I believe that was talked about a while back. The remote was "bent" in enough to rub on the spring. This as I remember was a manufacturing defect and the dealers were replacing them under warrantee.

Ah man I guess I missed that one, I'm out of warranty now but I'm gonna have to get with my dealership about that, they should have told me when I took it in for its first service.

The shock rub has been a pain in the A$$ for a few yrs, I've claimed lots only to have the next one do the same. 60/40
Coil maker blames the shock maker and back and forth.
New shocks supplier is on the way,

I have the same problem with the spring rubbing the reservoir.  The dealer replaced both my front shocks and they are rubbing again.  It seems as though some shocks rub and some don't.  I need this fixed before warranty is up.  The spring is about to rub a hole in the gas chamber and bladder.

Can the rod end be safely unscrewed without losing oil or nitrogen?  What about the needle valve inside?  I would like to take my rear shock rods ends off, clean them, apply thread locker and re torque them.  Is there a way to remove the spring without a spring compressor?

Just an update on this.  I pulled the springs off both my rear shocks.  The first shock I worked on was tight.  I couldn't budge the rod end in either direction with a 24mm wrench.  I cleaned the shock and re assembled it.  I was able to break the rod end on the second shock free.  I did not remove it for fear of having pressurized oil leak out of the damper tube.  I simply re tightened the rod end and re assembled the shock.  Piece of mind I guess.
