Have had an Icon stage 2 lift for ~2 years with ~15k miles on them, with a few moderately difficult off road trips. Recently developed a clunk front drivers side. Diagnosed as the KDSS hydraulic cylinder. Vehicle is currently at Glendale Toyota in Los Angeles area. Dealer won't cover under warranty.
The service manager defers to the "field tech specialist", who just consults over the phone and decides to deny warranty.
I then created a case with Toyota Customer Experience, and they have also allowed that decision to stand.

My 4runner is currently in their shop with a dismantled KDSS system, and the hydraulic cylinder unit (only comes as a unit with lines) costs $2046!! And they want to charge $2000 on top of that for diagnosis and then installation. I could almost get an Icon stage 7 for that amount!!

I am almost furious enough to get a lawyer involved, but not sure that will be worth my time and additional costs.

From reading through a couple other warranty threads, it would seem the burden of proof would be on Toyota to make the case that my Icon lift CAUSED the KDSS failure, and they have not done that, nor do I believe they would be able to do so.

Any suggestions would be welcome.
I clunked about 20k miles after my lift was installed. Just replace the KDSS sway bar bushings first. See if that helps... It was $125-ish for me (parts are minimal, dinged on the labor but they have to strap the system back and it's a PITA). The geometry has changed with the lift, so there's probably a harsher wear to those bushings now.

Mine is good to go after ~10k miles after the repair and about 116k miles on the truck.

And post a picture of the bushings as they currently sit!

I haven't gone back to take a look myself, but the mechanic said he was 100% sure. I talked them into a 15% discount on the total, but still a bit disappointed in this situation.

I need to read more about the mechanics of the hydraulic cylinder to see if it even makes sense that the 2" lift would significantly effect its function.

Will take some pics tomorrow when I get back to the dealership. I can see how the bushings would be more likely to wear out with the lift, but have a harder time seeing how the hydraulic cylinder would be affected by the change in geometry.

I appreciate the response!

Are you sure the cylinder actually has a problem or was that the dealer just throwing stuff at the wall to see what stuck? I just ask because I don't think there are a bunch of threads about KDSS cylinders failing. At least I don't think there are...

This is exactly why I am planning on going by tomorrow and taking a look myself. And I appreciate the suggestions on checking the bushing first.
If I don't see an obvious defect in the cylinder, I might ask them to replace the bushing first and see what happens.

Good luck, my man, and let us know what you find. Hope it's a cheaper fix!

So I had a clunk develop on drivers' side front area at about 5k miles. Was so annoyed at first I posted a video on YouTube trying to film it and see if others had ideas. for the last four years just decided it was KDSS and lived with it...

YouTube

Im now at 46k miles and had the ICON's rebuilt for the first time.... and the clunk is gone! Toytec found that some brass spacer ring of some sort inside had been out of position for a while and believed that to be the cause of the clunk.

Long story short... might not be KDSS. Try switching your coilovers from side to side. Replace bushings, then go from there.

Within 2000 miles of buying my 2018 I noticed the metal band clamp was off the driver's side KDSS sway bar bushing. It's there to help keep the bushing from extruding and I asked the dealer to replace it. They replaced the whole sway bar.

Shortly after that I added a 2.5" Radflo lift and E-rated KO2s. A few times a year since I've exercise the truck fairly vigorously.

At my 35K service I noticed that same band clamp off again, I then noticed the bushing had extruded and split radially. They replaced the whole sway bar again.

In both cases the dealer said they can't get the bushing alone, just the whole sway bar assembly. Since it looks like I'm going to need to replace that driver's side bushing every 15K-30K where are people getting the loose bushing from?

I also had issues with the metal clamp and just cut it off and used a zip tie. Worked pretty darn well!

This the same metal band you guys are having issues with? I have an icon stage 2 lift, 15k miles on it, 20k miles on the 4R. Was planning on just replacing the bushings. Seems like you can just buy and replace?

I'm at 40k miles on a 2019 and been having a clunking noise coming from the front driver side KDSS for quite sometime now; i recently got my bushings replaced and that didn't fix anything. I believe its coming from my hydraulic cylinder cause when I rock my vehicle side to side majority of the sound seems to be coming from that area and I can feel it when holding onto the sway bar at the same time; but if the hydraulic cylinder is to blame wouldn't the KDSS sensor/light appear on my dash? Driving performance also still feels the same, just driving with this clunking noise is annoying af! lol

I had the same issue with the fastener coming off. Dealership wanted to replace the entire sway bar. I just added a zip tie and has been holding on for months now. I'll just keep replacing

have you replaced your lower spherical bearings on your coilovers yet?
