Hello everyone,

I want to express my gratitude to all of you for the support I've received from this group since I became a Lexus owner.

I have a Lexus GX460 Premium. Lately, I've been experiencing some issues with the rear suspension of my car. It has been very bouncy, and even small bumps make the ride uncomfortable. This problem occurs intermittently; sometimes it's fine when I start the car in the morning, but then it becomes bouncy and then goes back to normal. I've also noticed that when it gets bouncy, I can't adjust the height using the switch – it becomes unresponsive.

I initially suspected the suspension bags, but upon inspection, everything seemed fine. The shock was replaced just a year ago, so I'm not sure what could be causing the issue.

Does anyone have any ideas about what might be causing this problem?

 

The GX460 Premium does not have Air Bags ... it has Springs ...

 

... Air Bags ... Springs ... no matter ... the Shocks provide damping ... so your description points to the Shocks being the issue ...

BTW ... shocks are always replaced in pairs ...

 

My bad. its Luxury version!

 

Shocks were replaced about a year ago. I also suspect air springs since the car height is not the same as before also I can hear an air leak. I am looking for after-market air springs. OEM is a rip-off.

 

HI mode cannot be selected above 18 MPH and LO mode cannot be selected above 7 MPH.

 

What shocks were installed? The OEM Lexus parts?

Good luck with that.

^^ ... if you do not tow, go with a Spring Conversion ...

 

Airbag Man! They make extended length variant as well if you're looking to lift while keeping air shocks

Not me but

 

I mean, even at 0 MPH.

 

KYB shocks.

Arnott's air bag looks good. but may be next time.

 

I do not plan to remove the KDSS system. it has its benefits in certain driving conditions.

 

I believe it's not a good idea to only lift the rear of the vehicle and leave the front unchanged. This could negatively impact the driving experience, damage the suspension, and limit articulation. It would be better to replace the entire suspension for extended travel, including the struts, arms, sway bars, and so on.

I'll definitely check the Airbag Man guys to see if they have an OEM replacement. Cheers!

 

they do have the regular height one as well. I believe it’s the same model with a S at the end
