Anybody have the procedures to replace just the front air springs on a '10 RR SC w/ VDC with new oem air springs/bags? I'm curious if it's worth my time vs replacing the full strut/spring assembly. Doing the entire assembly looks plug & play. I'm concerned about future leaks when replacing just the air springs/bags.

Pretty hard to mess up, google from 2002-2012 L322s even with VDC it is the same.

The only difference between a VDC truck and non VDC truck is the actual gas shock. Not the bag.


It is easy, doubt you'll have any leaks. Make sure to use lots of silicone spray on sealing o-rings. You'll want something like a powerful impact, makes the job go quicker like the main strut bolt and the inevitably stuck bolts holding the strut into place.

If you're over 120k miles you may still want to consider replacing the gas shock as well for sake of drivability. Makes the ride a touch smoother and less bouncy.

The biggest thing you can possibly screw up is the threads on the strut are plastic and the pex hose fitting is brass... crank the fitting in too hard and you'll strip every thread out of the strut.

I only have 76k miles on the SUV and there should be plenty of life left before needed to replace both front struts. I found this video on youtube showing the process to replace the air springs with Arnott bags.

Any recommendation for silicone spray for the o-rings? I have an 18v 1/2" Snap On Impact Wrench which should do the job for the tough bolts. I'll just use a ton of PB Blaster and let it sit for a day or so...

I just use wd40 silicone spray for all that stuff. wd40 silicone spray! some people say "wd40 isn't silicone" correct. but the brand also offers a silicone spray

I would suggest to use Dow Corning 111 on all the air line connections,
this will preserve the rubber O rings and prevent leaks in the future
