Replaced rear shocks on 2017 with air suspension and 3rd row. Couldn't find any reference online to interior parts to remove so I'm just sharing mine. All that needs to be removed is

Rh rear cargo area trim circled in red
Lh and rh 3rd row cup holders. They just pull up to remove
3rd row seat cushions. Pull up on front of cushion then pull forward
Trim under the third row seats. Just pull towards front of the car
pull carpet forward to expose shock mounts
Remove foam covers over the shock mounts









The shock removal is the same as what these poor range Rover owners detail in the video below.

More picks of the shocks disassembled. Very straight forward.

 

dang that's quite impressive; good job OP and thank you for sharing

 

Great write up!

What shocks did you use to replace?

 

Thank you

Just stock performance Bilstiens

 

That seems to be the only option.

What prompted the replacement? Time? Miles? Just because?

 

There wasn't sufficient dampening on the rebound (extension). Especially bad at highway speeds over larger undulations in the road. Suspension would unload too fast making for bouncy/unstable ride. I tow a fair amount as well. Discovery has ~105k miles
