Sometimes if you don’t catch that air bag leak early, you wind up burning out he compressor from it constantly running..

It was my turn. I'd been expecting it.

Just replaced both rear shocks on my '08 GX w/99Kmi. Not an inexpensive endeavor at just under ~$550/ea + ~$100 installation labor.

Briefly toyed with the idea of Bilsteins and FJ springs or an Old Man Emu set-up, but the speed and convenience of an OEM solution won out. Maybe next time?!

Front struts still allegedly look good, but I'll replace them soon enough along with upper shock mounts per @RCsGX (post 54 on https://www.clublexus.com/forums/gx-...eliable-4.html)

Height sensors and air bags still allegedly look good, too. I'll keep an eye and ear on their "up's and down's."

Happy motoring.

No idea of quality but there are now 3rd party adjustable shock options for $170/each.

Hi all, first post here. Thanks to everyone for contributing to the discussion above. Bought a 2009 GX470 two months ago and have been very happy with the car. Unfortunately it was rear-ended last week (Honda Civic), and although there was minimal damage to the rear bumper, the civic primary hit the spare tire, which was ripped off the mount and pushed forward into the air suspension reservoir, bending it, pulling out at least the driver side airbag line, pinching (but not definitely puncturing) the passenger airbag line, and damaging some other mounting brackets under the truck. After the accident, both rear airbags were deflated and we had a bumpy ride home, with the body resting directly on the rear axle. Insurance totaled the car because of the damage to the mounting brackets on the frame (“frame damage”), but structurally everything looks good, so I’m going to replace the air reservoir and some of the air lines myself (I’m a DIY hack at best) and try to get her back on the road. Backup plan is to put some coils in, but would prefer to have the air suspension working for the coil/airbag trick in the future.

Questions for the group:
  1. Has anyone used these air lines? https://www.ebay.com/i/201956244589?chn=ps If so, do they require any special hardware?
  2. Had anyone had a situation where the DLC3 connector trick above does not work? Did this yesterday to try to diagnose leaks, but the suspension height was still stuck in neutral position with no air compressor activity after couple attempts. Everything went as described in the video/writeup, but for some reason the reset didn’t work. I’m wondering if damaged solenoids in the reservoir or damaged reservoir could be the issue?
