Description: If your SRAM AXS electronic derailleur doesn't...

Steps:

  1. Begin by removing the derailleur from the bike. As covered in the video SRAM GX and S1000 Eagle Transmission Rear Derailleur Rebuild, remove the:
  2. pulley cage and damper assembly
  3. You can remove the pulley cage with the chain still attached by rotating the derailleur body counter-clockwise.
  4. skid plate (one 2mm allen screw)
  5. upper and lower parts of the outer parallelogram link (two 2.5mm allen bolts)

  6. The P-Knuckle contains a strong spring that can move unexpectedly, pinch, or stab you. Use caution when removing and reinstalling.
  7. The spring is under the least tension when the derailleur is shifted fully inboard to the largest/easiest gear. If you can still power your derailleur, shift into this position by repeatedly double-tapping the AXS button.
  8. Undo the two 2.5mm security allen bolts and carefully pull the lower and then upper halves of the inner parallelogram link off.
  9. When reassembling, slip the metal arm from the motor under the spring before sliding the upper half of the inner link into place.

  10. Remove the upper arms, small white bushing, pivot axles, and GX nameplate from the motor case.
  11. Take careful note of where each bolt belongs, they are all slightly different!
  12. When reassembling, it is helpful to get everything else loosely in place before wiggling the name plate into position.

  14. You can test the derailleur at this point by holding a battery against the pogo pins and pressing the AXS button. If a green light appears and the derailleur moves, congrats - you fixed it!
