Replacement is pretty straight forward, but since there aren't many in the U.S. They may be hard to come by. Luckily my local dealer could source one overnight from the local depot at $235.
You'll want to first take off the weather stripping and t-clips that hold the black abs panels above the firewall. USE CARE! You need to coax the weather stripping off each one, and then use needle nose to punch and pull out. when done, put them back in the weather stripping.
Unbolt the wipers. You need to fully extend and release tension to get them off - again be careful so you don't strip the splines inside. Then work to unbolt the linkage from the body where it mounts (10mm socket, with extension for clearance over hood)
Unplug and unbolt the wiper assembly - 4 bolts at 10mm. If you have a dual battery, you'll need to disconnect the cable nearest the fire wall for clearance.
Install new linkage starting with wiper mounts. Don't put the wiper arms back on yet. You'll need to jockey the linkage to extend the arm to the motor.
The end of the linkage that connects to the motor has a clip to attach to the firewall. Hang it there to apply pressure when mounting the wiper motor. It will pop in.
Fully extended, the wipers will be straight up. If you suffer a failure and want to try to reconnect, you should move your wipers there first.
Remount the wiper motor, plug in, and reinstall the plastic panels, followed by the weatherstripping, and lastly the wiper arms at the down position.
Pretty easy - about 45 mins all in. Just don't forget to remove any tools before closing the hood and breaking your less than week old windshield like i did.
Here is a picture I the failed component. Dorman makes linkage bushings, not sure of the part # though. Will try to take measurements and post back up at a later date.
