XREAS question

2005 4Runner Sport w/113K miles. Bought it used in 2006 with 20K miles on it.

Short question: Is the hydraulic line of the XREAS system tied into the brake master cylinder at all? After all the research I've done, I have not seen that to be the case. However, I have an indy mechanic who thinks it is based on what he's seeing when looking at it. And he's called up the local Toyota service dept to verify, who told him that that was indeed the case.

Back story: A few months ago I decided to replace the shocks on my 4Runner. I didn't do my research and just bought standard shocks. I took it up to my indy mechanic to have them put on, and he said that the ones I have in there have hydraulic lines going into them. He wasn't familiar with this, so he didn't want to touch it. I knew about XREAS, but figured it was a limited model option only, but on that day I learned that I have it in my Sport. Or so I think.

I do some research, and from what I read it seems fairly simple to close off the hydraulic lines and replace the Xreas shocks with a standard setup. I take the 4Runner back up to my indy yesterday to have him look around to see what else I'd need to swap in my new shocks. A few hours later, he laid on me what I wrote in the first paragraph. He said the Toyota tech told him that I could buy OEM XREAS shocks and have my indy put them on, but those are a bit more expensive.

So i don't know....the idea of another hydraulic system tied into the braking system doesn't make sense to me, and if my indy mechanic and my local Toyota service dept think that to be the case but are wrong, I probably don't want either of them touching it whether they're replacing the existing shocks with OEM XREAS or the standard ones I bought. I need to figure out how much I want to pursue this and pay to have these replaced.

Answer: no, XREAS is not connected to your master cylinder or anything else. It's a closed loop system. Yes, it's a hydraulic but the tubes he sees only connect the diagonal shock together (RR and LF, LR and RF).

Please refer to this page: J.a. 4runner - lift

Thanks, darkie3495. Yeah, I've seen that diagram a few times and I tried to print it out for my mechanic yesterday (but my printer failed).

And the claim that it was tied into my braking system didn't make sense to me...if I blow a shock does that mean my brakes fail? Heh.

I'm not sure what I get for going back to my mechanic and proving him wrong...maybe he just doesn't want to/feel comfortable working on it. That's for me to figure out, though.

Thanks again.

I find this very hard to believe. I know there are some dealer service horror stories out there... But either:
1) this dealer is as daft as your mechanic,
2) this dealer is setting up your mechanic to look like a moron, or
3) your mechanic is blowing smoke up your backside and never made the call.

My vote is #3

The lines on the X-REAS system look similar to brake lines, but two are separate from each other. Many SE owners have removed X-REAS from their 4Runners in favor of coil-overs, etc.

What is Xreas exactly?
What is Xreas exactly?

Installation:
Although I do as much work on the 4R myself as possible, both maintenance and mods, Working on the suspension is not really something I wanted to do. Through my research on lifting the 4Runner, I found that it is pretty straightforward without XREAS, but having an XREAS equipped 4R makes the job a different ballgame, one in which your local shop has most likley not encountered. You cannot disconnect the XREAS hydraulic lines connected to the shocks at all. Once fluid leaks out and air enters in, the system needs to be entirely replaced. There is no way to flush or recharge the system. So this job requires working in the wheel well with handheld spring compressors. Additionally there is the Skid Control Sensor wires right there that cannot be stretched or damaged. Same goes for the brake lines. Various shops I spoke with would have nothing to do with a job like that, with them taking responsibility for potentially runing an expensive XREAS or ABS/Traction/Skid Control system, and not being able to use their wall mounted compressors. Actually, after talking with a bunch of shops, I did not want them to touch my vehicle afterall. I would have to stand over them to make sure the job was done to my specs and guide them through the job, paying for many hours of labor. So I decide to do it myself.

My only thing to add to this is that you DO NOT disconnect the hydraulic lines AT the shocks themselves. Toyota is VERY specific to caution technicians to disconnect the lines at the accumulators bewteen the two shocks. These are high pressure hydraulic systems that can hurt you, granted most of them will be leaking and probably lower pressure if any left in them. But do you really want to take that chance?

Just helpful advice if you are going to do it yourself, rather you didn't get hurt if you wanted to do it yourself.

K.C., Thanks for the insight - All that just makes me wonder if what my mechanic told me was just some combination of what ur7x wrote, and that just doesn't want to risk touching it all.

I can't fault him for wanting to be cautious and forgo working on a system he's not familiar with. He didn't charge me for the time he was looking at it...or not looking at it

You got that right!!

Some mechanics don't want to touch it because of risk.

It's like when friends ask for help, for them, not a problem, if it's for their lady, I have to think about it, because I don't want them nagging & jabbering at me haha

I'm considering purchase of an 07 Sport. When the day comes that 1, 2, or all shocks needed replacement or the systems fails: the system is independent and can be replaced with standard shocks, or no? Do people do that?

The system is cross-linked, meaning the right front and left rear shocks are hydraulically linked. That said, you should never replace a single leaking shock with a standard shock. If you have one XREAS shock that is leaking and you want to replace the XREAS system with standard shocks, it's time to buy 4 of them and rip out the XREAS entirely.

You can easily replace the entire XREAS system with standard shocks. Just make sure you install 4 new shocks once you pull out even one XREAS shock.
