So... the truck has been dropping the front end while parked and triggering the suspension light (yellow) after 15 minutes of driving. Assumed it was the front valve block, so today I swapped it out. Still got the suspension light after driving for 10 - 15 minutes. I'm thinking it's got to be the front air bags at this point. Any thoughts of what else it could be? Thanx...

 

Is it still dropping when parked after the block swap?

Sounds like multiple issues. Codes would be a BIG help. If the compressor has been over-worked or is original it may be on the way out and drawing too much amperage. Or it may be over-working due to a leak in which case its timing out thus throwing a fault.

 

putt it in off road height, shut it off, jump out and listen at both corners. If a bag is leaking that bad to throw a code after 15 min, you will hear it.

 

Dakota, the compressor is an AMK and sounds normal when cycling on... doesn't run too long to fill tank.

Abran, will do that tomorrow. If it's not he bags, what else could it be. Tanks been replaced.... I hope it's not the lines...

 

It’s the bags. The only time I have seen a problem with the lines is when someone while repairing damages them.

did you replace or rebuild the front valve block?

Did you connect correctly? Line with white stripe in the lower port?

 

What about the central valve near the compressor? I chose to replace all components at the same time, all three valve blocks, and the compressor. No more dancing LR3 at the stoplight. So no way of knowing, but I'm still on original suspension at all 4 corners, and all working just fine.

 

Anything is possible. But a diagnosis would be best.

have you done the battery disconnect and check back 12 hours later thing?

 

I spent countless hours trying to find the potential leak point that my wife thought I was having an affair with our LR3 at one point. I'm an HVAC expert and Engineer and can find leaks that nobody could find, but there is only so much one can do on the LR3. At some point I said to heck with it an replaced everything, despite my work and even the dealership trying to find the source. I thought I would have to add the suspension to the list, but was surprised at how well things worked.

 

HVAC, Leak master!

I learned to use winded to find leaks from working HVAC a lifetime ago.

 

Yeah, it's the bags. Extended mode, shut off and listened and sure enough for a few seconds there was air hissing from the drivers wheel well. Couldn't make it around to the passenger side fast enough before it stopped. Btw. my lower airline was lime green... the other two were black.

Now to find me a good deal on some Arnott's...

Thanx for the help fella's
