The corner valve is more likely your problem. They leak back to the reservoirOur front air bags are leaking and need replacing. I have found so many different brands and many different prices..can anyone recommend a specific one? I personally want to get rid of the whole system but wife likes the ride
Yes. Pull back the front of the right front wheel house panel. You should be able to locate the corner valve attached to the backside of the fry bumper bar. Lift upward on the valve to slide its mounting bushings out of its 3 holes.
Now with a good pair of hose clamping pliers. The kind used to close off a brake hose when you take a caliper off. You should be able to figure out what hose is feeding the valve from the reservoir. Clamp it off and wait the amount of time it usually takes to sink.
Another thing that helps is to put the truck in off road height and disconnect the battery. Then you will get a much better idea if one corner is leaking down because the car won't wake up and try to level itself.
I'm sure eventually they will get brittle, but I haven't encountered that yet. They aren't like DII plastic coolant lines that break when looked at from a distance. If you clamp them off, worst case you will end up with a slight crease in the line. I don't think I've seen more than one or two front springs leaking on LR3 (seen a bunch on RRS). I would go with the valve block if there is a front suspension leak. Ideally you should verify that it is both front springs leaking down.I would not try to clamp those lines. They are not very flexible especially if old. Besides, for air you'd have to really smash the shit out of one to stop a hissing sound. Then, I think you'd definitely end up with a permanent hissing sound....
