Air Spring Module - Rear - LH (Remove and Replace)
Correction Code 31106002
- 2024-08-19: Added note to perform air dryer regeneration when replacing component because of a leak.
Note
When replacing an air spring module for
failure, inspect all air spring modules for leak, wear, or reduced performance, and
replace them as necessary.
Removal
-
Remove the rear center apron and inspect the vehicle for a Schrader fill valve on the RH shock tower. See
Underhood Apron - Center - Rear (Remove and Replace).
- If the vehicle does not have a Schrader fill valve, install it now. See Fill Valve - Air (Retrofit). Then continue to the next step.
- If the vehicle has a Schrader fill valve, continue to the next step.
- Raise the vehicle and depressurize the rear LH air spring module. See Air Suspension - Pressurize/Depressurize - One Air Spring.
- Remove the rear LH arch liner. See Wheel Arch Liner - Rear - LH (Remove and Replace) .
-
Release the fitting for the air suspension line (brown) from the rear LH air spring module (torque 2 Nm).
-
For each released end of an air suspension line, use a flat blade screwdriver to snap off the old collet, and discard the collet and nut (VOSS fitting).
- Use a stand to partially support the rear LH suspension.
- Remove the bolt that secures the air spring module to the knuckle (torque 140 Nm).
- Remove the stand and lower the vehicle to a working height.
- Remove the upper LH parcel shelf support. See Support - Parcel Shelf - LH (Remove and Replace) .
-
Remove the foam HVAC ducting.
- Remove any insulation that covers the nuts that secure the air spring module.
- Remove the nuts (x3) (torque 39 Nm).
- Carefully remove the air spring module from the vehicle.
Installation
CAUTION
Replace all nylon-insert
locknuts.
CAUTION
Replace all patchbolt(s).
Note
Clean the affected areas before
installation.
CAUTION
Only fully tighten suspension nuts
and bolts when the vehicle is on a 4-post lift and the suspension is in the ride
height position.
Installation procedure is the reverse of removal, except for the following:
-
Install and hand-tighten a new collet and nut (VOSS fitting).
NoteA plastic plug holds the fitting together before and during installation.
- Remove the plastic plug from the new fitting.
- Tighten the new fitting (torque 2 Nm).
- Insert the air suspension line fully into the fitting, and then lightly pull on the line to make sure that it is secure.
- Make sure that all air suspension lines are securely reconnected before continuing.
-
Refill the new air spring module
or air suspension system. See GUID-60108A19-C4AF-49B5-818B-417D8B08DC55.html or Air Suspension - Pressurize/Depressurize - Full System
Note
If the component was replaced because of a leak, perform the air dryer regeneration procedure to purge the accumulated moisture from the dryer. See Air Dryer - Tesla Air Suspension (Regenerate), and add correction code 31101008 as a separate activity to the Service Visit.
- Raise the vehicle on a 4-post lift and torque all suspension components while the vehicle is at ride height.
- Refer to the Alignment Requirement tables to determine whether an EPAS alignment check (EC) or four wheel alignment check (AC) is necessary. If performed, add the alignment check/adjust as a separate activity. See Alignment Requirement - Suspension.
