The plastic cover over the shaft only snaps in place. Remove it from the bottom first and it pivots at the top and will pull off. To take apart the large oval cover will require that the whole unit and articulating arm be removed.

1) Remove the leaf screen.

2) remove the nut that presses the arm onto the wiper motor. Then pry off the arm. It will pop off given some elbow.

3) remove the three bolts holding the motor in place. Also the bolt holding the bracket in place next to the motor and there is a nut above the motor against the firewall.

4) Remove the two nuts on either side of the center pivot assembly. Thay are also up against the firewall. Then the bolt at te bottom holding a rubber grommeted bracket.

5) The whole assembly can be removed.

6) Remove the bolt at the center of the back that the arm is attached. Be carefull of any washers and o-rings that are removed and their order of their removal.

7) The body can be rotated and at ONE specific point can be pulled apart.

8) Clean the slide rails and relube. I used a spray lithium grease.

9) Clean the gear and mating teeth on mating side. I used good bearing grease.

10) Hand turn gear until the shaft is at it's most fully retracted position.

11) Mate the two halfs back together. Rotate until the rectangular hole on the side mates up with two side-by-side marks. Keeping in this position. Put the o-ring, washers and arm back to place and tighten the nut. This must be in the same position as you removed it.

12) Put the unit back in in reverse order.

13) Pray that I didn't forget anything important.

I think I did not align the arm on the center unit as it was originally because I underwipe the passenger side and over wipe the driver side.

If someone can. Take a pictue of the underside of the oval unit before disassembly. This can be used to make sure orientation is correct.

Post it so I can check mine.

(Yes, I should have taken pictures too...)
