2003-2009 Lexus Gx470/Toyota 4 Runner Air Spring DIY

My air spring/air bags are finally leaking on my 2003 Lexus GX470 (similar to Toyota 4Runner I assume). This video is how I replaced them with OEM from eBay. The rubber on the air bag will eventually become brittle and crack and cause air leak and should be replaced. Mine lasted almost 20 years, probably because I'm in CA and not in region with super cold freezing winter temps.

I have been searching for a complete video of air spring replacement and glad to finally find one! Thank you Jeremy!

[@matty_o]

Thanks for your video as everyone else pulled the bags for conventional springs. 2007 4Runner with ride high control which automatically includes Xreas

I see no rust at your bottom of your lx470 wow nice

[@Moondoggy1941]

My 2007 GX 470 from Ca. has zero rust as well.

[@itzjere]

Glad to see you are still wrenching, even if it's not the 997. Hope all is well.

[@atm4jim]

Thanks Jeremy - it's been a while, how have you been? anything new with your 997tt?

[@itzjere]

Not a whole lot, which I suppose is a good thing. Just adding fuel and enjoying the ride.

[@atm4jim]

@@itzjere Glad to hear, I thought you may have move on to another toy car by now. Seems prices on these and similar cars have gone up recently. Let me know when you want to go to Sac Raceway before they close down, maybe when the weather cools down.

It looks really nice!

[@jonathanwilliams6922]

Thanks man

[@allanreager3306]

What size are those Michelin defenders?

[@uhitsclay]

i may sound dumb, but how does the bag release air ?

[@Noypi54494]

Great video my friend! Can I ask if you had to replace your compressor or air valve? I have a 2012 GX460 and just replaced the OEM rear mechanical shocks recently and now have to replace the air shocks. The ride is like a jack hammer still in rear.

[@atm4jim]

No, haven't needed to replace them, though I've read they do eventually wear out especially if you have a leak and the compressor is always running. My ride was like a jack hammer because the suspension was sitting at the bottom and thus no suspension travel due to air spring leak due to rubber's age. Thanks.

[@Noypi54494]

@atm4jim Thank You! Looks like I have to replace air shocks like you did then.

[@matty_o]

Clean underneath. No rust

[@failingdisciple938]

Where do the o-rings go?

[@mattwernecke2342]

Always go with oem if possible . I've been burned before.

[@fuertep2do]

Woooo nice video man serper . I heve another lexusgx470 it's leaks air when i driving it's ok but after 5 minutes its like no suspension very crazy do you think it's tha seme problem????

[@atm4jim]

Very possible, hard to say without testing for leaks or looking at the bladder for rubber rot/cracks.

[@fuertep2do]

@@atm4jim yeah but it's like you said very poble .. well thank's so much

[@ArcadiaBlvdd]

thanks for the detailed push in, and circled photos.... im having the same issue w my 04' gx sometimes i rides bouncy if i let it rise on its own the ride aint bad... any ideas or solutions? greatly appreciate any words of advice

[@atm4jim]

Could be a number of reasons why it's bouncy but would start by checking if air bag has a leak somewhere or if it hasn't been replaced, I'm sure the rubber has rotted by now. The system has several components like air compressor and sensors so you need to isolate/troubleshoot.

[@teale4ever]

Ooh, aaah, you sound just like Sean Connery. You're making me so hot with all that tech talk. O m g.

[@Khmer-US]

Doesn't looks easy lol
