Hey guys, let me start out by saying...:happens:
I'm in the process of installing a Toytec leveling kit (3"F/2"R) and I'm pretty sure I screwed my XREAS system up. I've done some research that I will compile here for future reference, and I'll most likely be taking a trip to the dealer next week if I notice anything strange so I can add that experience here too.
Having known little about XREAS prior to starting the installation process, I shouldn't have jumped into it with such confidence/carelessness as I did. Hindsight 20/20.
To make a long story short, the hydraulic line that is connected to the bottom of the shock was slightly unscrewed, but enough to release the pressure in the line and shoot hydraulic fluid everywhere. Apparently there are two separate hydraulic systems: the front passenger side is linked to the rear driver side, and the front driver side is linked to the rear passenger side. I had only raised the front off the ground and I was working on the front driver's side.
After realized I probably ruined the system by releasing a little bit of pressure, I did some research and found that there is a disconnect valve. I then removed the coilover assembly with the hose still attached to the bottom of the shock and hydraulic oil was steadily dripping out of the hose. I probably lost around 6-8oz of hydraulic fluid just on that one line/shock. But anyways, it's connected back to the system now, valve re-opened, no leaks.
Here's some things I found from this and other forums about XREAS (could possibly be untrue):
- XREAS cannot be bled/refilled. The components are installed pre-filled, hence the valves at each disconnect location.
- A fellow T4R user says here that removing the hydraulic line from the shock is a sure way of destroying that shock. He/she also mentions that XREAS is a completely closed system.
- This is the proper way to remove any XREAS components
- Apparently XREAS has great benefits for on-road use like better cornering and easier handling. XREAS reportedly doesn't do much for off-road travel.
If anyone's had experience or has been in my shoes and would like to propose ideas, make suggestions, or maybe some reassurance, I'd appreciate it. I'll post up what the dealer says when I pick their brains about what can and cannot be done with XREAS repair.
