Suspension Question (1 Viewer)

[SHERMAN FJ62]

My 04 GX is stock truck and the PO replaced the rear air springs with new ones. I have approx 165k on the truck. Like the suspension on the truck and have three other cruisers for off-road play. My issue is sometime when I hit ruff or bad pavement the truck really shutters from front to back. This can happen at hwy speeds all the way down to 30 mph. The setting for the springs changes it somewhat but sometimes feels like I am running across a washboard road or the suspension is just too stiff. Otherwise the ride is very good. The ride seems to be upset by those unexpected bumps. The front and rear suspension don't seem to be leaking. Is this just the nature of the truck or is this a sign of a sensor or something else going bad?

Thanks

The shuttering is not normal. Stating the obvious, I would start checking for loose or damaged parts.

Are the new air bags OEM or aftermarket? Is the light on the dash set to L / N / H and or blinking?

FYI the suspension dial (Comfort-Sport) is just for the shocks. Has nothing to do with the rear air bags.

Bad shocks. Are they original? Sounds like no dampening.

Check the distance between the frame mounted bumpstops and the axle. It may be that the "normal" height needs to be adjusted up to keep the axle from bottoming out on larger bumps.

Thanks I will check it. The shocks don’t seem to be week but they maybe

I would bet bad shocks. The air ride really bounces and does weird things without dampening. Mine had the same issue when I bought it. The airbags were working but the shocks were gone. It was so bad the previous owner thought the transmission was slipping.

How did you fix it?

I wager....new shocks!

I ended up replacing mine with a lift kit, new shocks, and rear coil conversion.
