Lexus RX and Toyota Highlander
Extra Wide Armrest
1. Using your fingers, remove the plastic cap from the side of the original armrest (lightly pull around edges until it pops off).
2. Using a 9/16” or 14mm socket with extension, remove original bolt, armrest and plastic washer, which is in between armrest and seat.
3. Locate the small hole of the Armrest Bracket (supplied) onto the 5/16” diameter pin on the seat. Line up the large hole in the bracket with the threaded hole in seat. Install the bracket with the supplied bolt and lockwasher using an 11/16” or 17mm socket.
4. Place the large nylon washer over the threaded shaft on the bracket. Place the armrest onto the threaded shaft. Unzip the zipper on the armrest about half way to locate the hole in the side of armrest. Using a 1/2” or 13mm socket and a long extension, install the bolt and small nylon washer into the threaded shaft and tighten until armrest stays half way up on its own but still goes up and down smoothly. Do not over tighten .
Redo the zipper. Installation is complete.
