  • DIY Grande 120 OEM Airbag replacement

    I hear there are a few OEM Grande's around with leaking airbags, so I thought I'd write this. Hope it goes smoothly for you!

    Reason: Airbags were leaking often, dropping over night and could be heard hissing after some trips. Leak was seen with a soapy water spray coming from the bulge in the rubber near the base. This rubber was visibly cracked as well.

    Parts:
    -Special Service Tool = Caulking gun nozzle, slit along its length. (Worked beautifully and saves $30 from Toyota!)

    -OEM Toyota grande airbags (RRP about $450 per rear corner).
    If you want to lift or go for a thicker airbag, Airbagman looks good (See DIY Airbagman post by AMTS). I wanted to keep standard height for towing, and our oem airbags have lasted 10years. Not the most adventurous choice but a price comparative & simple install.
    OEM airbags come with new internal o-rings/plates/retaining prongs inside the elbow connector. (Non-reusable part if your refitting the old airbag)

    Tools:
    Long screwdriver
    Trolley jack
    Wooden Blocks for extra lift
    Second set of hands (thanks Philjay38)
    Wire (on standby to hold spring clip while inserting or to help remove it)
    Torch & small mirror to check alignment
    Safety glasses (protect your your eyes from your dirty Prado)

    Time: About 2hrs at a slow pace on a hot day.

    Cut a slit along the length of your caulking gun nozzle, the length and thickness was fine with the one I used. Spread it open with a screwdriver to soften up the edges and widen for fitting.

    I mostly followed the process as per repair manual, diagrams of the fittings were helpful.

    Drivers side:
    -Start with drivers side, easier access to learn the connectors.

    -Turn off height control

    -Jack chassis rail, take wheels off for easier working. I jacked and put stands under the chassis rail in front of the rear wheel, you could also jack under the rear diff. The diff should hang down while swapping the airbags to give you enough room fit them through. (You're very much under your 2T plus prado here, be careful! Chock the front wheels, etc)

    -Remove Air line: Squeeze and slide back the plastic retaining cover. (You can see the air line connector from back under the passenger side wheel)
    Press on the "SST nozzle" on to the hose. Push it into the airbag elbow fitting, you can feel it nudge open the retaining prongs.
    Pull the airline gently, while the SST is inserted. It takes a little force for the bead on the air hose to slip out, the pressurised air will gush out. Keep the airline clean.

    -Remove Spring clip: remove the spring clip, I pried it with a screwdriver from the wheel well side.

    -Remove the airbag: it should easily compress and detach from the upper mount (the bottom of the airbag is not tethered but just sits into the lower mount)

    ...

    -INSTALL the new airbag in place (don't compress or expand the airbag by hand while fitting) Put a rag or a chock under the airbag to hold in place temporarily.

    -Connect the airline: (Unlike the repair Manual, for the drivers side I installed the airline before the retaining clip, as there was enough slack in the airline to feed it over and back through the top mount, allowing better access to connect the airline underneath)
    Take off the SST and make sure the airline is clean of dirt. Feed the line over the top of the mount and into the hole where the elbow fitting goes. (As mentioned)
    Push in the airline, you'll feel the bead of the airline run past the retaining prongs and bed in. (I didn't grease it, it looked like there was grease in the new elbow connector, and I haven't had any leaks as yet)

    -Refit the plastic retaining cover, the handles should be horizontal/on the side, away from the holes in the elbow fitting. Pull the airline gently to check it is firm.

    -Fit the spring clip back into the groove of the upper airbag end cap, a second person with a torch in the wheel well helps here. You can position it with your finger from under the car and push it in.


    -Seat the lower airbag mount:
    Fit the wheel back on. Jack up the rear diff to take the weight of the car.
    Watch and guide the lower mount into the key hole in the lower suspension mount while raising the diff. The car will be on its bump stop when raising as there is no air in the bag. Raise up the car enough to remove the jack stands, again you might need additional wooden blocks when using a standard trolley jack.

    -Fill the airbag:
    Lower the car down to the ground, turn on the ignition and reactivate the height control (press the height control "off" button so the light on the dash dissapears). The compressor should run (near the rear diff), and the bags fill to the normal height!

    Passenger side:
    This is harder to access and jack up due to the long range tank and extra wiring in the way. At least you know how the connectors work now though!
    I jacked from the rear chassis rail but the diff is probably lower and easier.
    We removed/attached the spring clip via keyhole surgery from the wheel well side also. You can only just get a hand in far enough to guide it in place from under the car before pushing it in from the wheel well side with a screwdriver. Torch and a small mirror came in handy to check the clip was in position.

    "Normal" height is about 780mm, "High" setting is about 825mm, after first fitting.

        JQVM,

        I've read your post with great interest now as I consider embarking on replacing my bags with taller bags as part of a 2" lift.

        Is the spring clip that you refer to actually securing the top of the bag to the upper mount, or is it just a support for the air line?

        You've already described it pretty well, but I drove the rear up on ramps tonight and it looks near impossible to access both the spring clip and the air line connector given the space between the top of the bag and the vehicle body - at least without running risk of getting dirt in the line. Did you access the air line from the inboard side in each case? Perhaps when it is lifted by the chassis & the diff at max droop it will be easier to see what I'm doing...

        Cheers,

        David.

          Hi Dave,
          Yes the metal spring clip just holds the top of the bag in place. The clip attaches to the notch in the round protrusion on top of the airbag as shown in this photo.

          I pretty much had to do the work by feel, and try and be careful to not get the airline dirty when reinserting. You should be able to see the driver-side airline from under the passenger wheel to get your bearings. Yes, it's a lot easier to get your hand up above the mount once the car is jacked and wheels are off. Though mine is a 120 series, it should hopefully be similar for your 150.

          Sorry for the late reply, was out bush field testing!

                As a matter of interest, what would a mechanic charge for this replacement?

                  Mine charged $350 to swap both airbags & do the front CV boots - but that was a bit of mates rates.

                      I got mine fitted $350 cheaper than that!. I am grateful to Andrew Su for his assistance and good company, although he did overstay his welcome by making it look harder than it should have been.

                      Might add that I did the sensor lowering adjustment yesterday and got 40mm lift in the rear. I don't expect this will stress the bags given a set of amts rear bag spacers were also given a new home as part of the bag replacement.

                        Andrew's Airbag-Spacers are awesome! I'm riding a pair for one year now and they work brilliantly - less stress on the airbags with a 2'' lift and smoother ride due to less pressure in the bags at the same riding height. The quality of the parts is excellent too. I can only recommend those spacers for lifted Grandes with OEM-airbags.

                        And Andrew is a very kind and helpful guy, btw :-D

                        @JQVM: Thanks for the write up mate, very good description!

                            Make sure you get genuine airbags. There are cheap copies out there and the materials are different.

                              Thanks guys... replaced air bags last weekend after 15 years service life.

                              Toyota quoted me parts and labour $1800 plus they wanted the car for two days...!! No thanks

                              Ended up picking up OEM for $527 a pair and did it myself. It’s took me around 2hrs to do the job..
