The ride height sensor is a moving part, and like all moving parts, they will eventually wear out. So, anybody know if there is a specific order to do this? Posted on Jan 24, 2009 Is the suspension fluid low. It started to get worse and I brought it back to my original Lexus dealer. With input from sensors, a control module directs more or less hydraulic fluid to be forced into the shocks, therefore controlling the dampening rate while the vehicle is moving. The downside is the complexity and expense of repairs.
Specifically warned against break fluid. Happ to answer any other questions. If you remove it, you need a block-off plate for the head. The quality of the parts is guaranteed by Strutmasters' Lifetime Limited Warranty. For the money I have in this caliber of vehicle by buying used; I can justify to myself replacing them when they fail with new parts. Unfortunately, my wife threw away the pages I printed and I can't remember exactly how I did it. I've never seen it mentioned on the 60k service.
I went back to the Toyota dealer and they are denying responsiblity. In the next couple years the lifespan will be found out more definitively I think. He claimed that there was no visible difference in the fluids appearance, smell or touch. Both sides will lower like the front did and you should drain ~0. Most of us over 100k haven't replaced them yet Jim but I don't think any of us have close to 200k yet either. Again close the bleeder as fluid flow stops. Do use a hose on the bleeder plug to direct the fluid into a catch bottle, as the emulsified fluid comes out under a great deal of pressure.
Customers appreciate the detailed instructions that help them get the kit installed in as little as one hour per wheel. I guess it is supposed to have a hydraulic fluid in it which would be very thin but instead there was an oil based fluid that was much thicker and caused these problems. Both sides will lower together because they are hydraulically connected and you should drain ~0. The nitrogen accumulators are plumbed downstream, and have a membrane that separates the fluid-filled portion of the sphere from the nitrogen-filled half. If driving at higher speeds it is normal for it to drop just a bit and resume to balanced height when parked.
I imagine one could replace the accumulators yourself probably like replacing brake components? Victor just curious about the wrong fluid in the suspension reservoir, i have a 1999 lx 470 with a similar problem. It all depends of the loads and driving conditions the truck has to put up with. Removal of the entire height control system is cost prohibitive. When emulsified fluid containing air is discharged, tighten bleeder screw to specification. Close bleeder when vehicle is close to bottom. The ride will become very hard at this point. By using the Service, you agree to the collection and use of information in accordance with this policy.
Furthermore, it's not at all wasteful of new fluid as you remove nearly all of the old stuff and recharge the whole system with fresh fluid in just one cycle. There is nothing wrong with leaving the level slightly over the max line. It could also be that your ride height sensons are out of adjustment or broken. You're done, confirm that the reservoir fluid level is correct - between max and min at N height with the engine running. When it does so, it opens a valve and pumps more hydaulic fluid into the dampers to raise the chassis back off the axle. It looks like I have a serious issue with wrong fluid in the system. It would lower on its own or when I came to a stop.
Aftermarket kits, as far as I am aware, do provide an alternative to buying the factory parts. I guess that liquid could need replacement as well. There is a fluid pump under the hood on the passenger side top corner mounted to the firewall, It pumps fluid into the shocks and raises and lowers the vehicle when you push the ride height adjustment button. I was looking at my Jan '05 Landcruiser magazine from Japan and there's a section on 100 series maintenance. A couple of months ago I brought it to a Toyota dealer for an oil change and had the fluids topped off. But, if you do decide to ditch the system, look at all the components and make sure you account for them.
Just by a per chance event, a friend recently asked me to tow their new 24' Jurgens lightweight caravan which has a tare weight of 1600 kgs unloaded and I discovered that my Lexus began rocking not swaying over some uneven road surfaces. It should reset itself when you turn back on the air supply system. Remove all of the old fluid from reservoir. Jack up the car enough to raise the concerned tire off the ground. And I guess I could drain the pipes between the Damping Actuators and the shocks, but would there be a problem of air inside afterwards. Do these have the typical lifespan of shocks 30K or 60K mi , or are they designed to last 20 yrs and 300K miles? Lossen the nuts of the tire to change. When a sensor malfunction exists the vehicle will not even try to raise or lower because it doesnt know which way to go.
An inability to maintain its proper ride height is a bad sign. Fill with new clean fluid, I usually put the whole can in. The whole system will refill and recharge with new fluid from the reservoir and the level in the reservoir will be drawn down to slightly over the max line if everything has gone as expected. It will be very close to completely full. Has anyone had any similar experience and can suggest what I can do to firm up the suspension so that I can tow a more heavy weight caravan? For the past 2 years I have had it serviced only at the same Lexus dealership with no problems. It is intended to remove as much old fluid as practical in a quick and efficient manner.
Repeat procedure for left and right damping force control actuators alternately.

By the sound of your example I would say that Your ride height sensors are broken or out of adjustment. Has anybody fitted Polyair air bags that support the coil springs? Now you should have drained very close to 1 liter 0. That's sort of the position I took on my 99, as well. I got a price from a local repair shop that I used to take my Landcruiser to for half the price of what Lexus was going to charge me for the fluid flush. Is it reasonable to assume that the fluid would begin to break down at 60,000 miles? There is nothing wrong with leaving the level slightly over the max line.
