All of the Haldex RNT26 kits I have bought came with an instruction sheet.

If someone could take a picture of the sheet and post it here, both I and the next unfortunate soul without one would greatly appreciate it. Otherwise, fingers crossed for responses from Haldex and/or the vendor I bought the kit from.

Hopefully you got an answer, but found this in the sealed white envelope with all the gaskets

I suspect you will still find leakage elsewhere. There is an output check valve on the air dryer, so once the air is pumped past that, there should be no going back to the compressor... If it is happening while driving, i would first inspect the park air lines, anti-compound valve and spring chambers. a park chamber leak would pass out thru the cage bolt holes. Depending on your year, you may also have a remote control valve inboard of the pri-sec tanks that disconnects air to the air/hydraulic pump when park air is applied.

Chock the wheels release the park brakes, a bad 2way could send park air out the front red glad-hand vent. Are the rear glad-hands capped/sealed? Fronts are vented, rears must be sealed...

Sorry for my ignorance. Where is this two way valve located? We have air coming out of our Red glad hand on the A1. TY

There's three two way valves behind the driver's side step curtain. Look UP behind the step with the washer bottle.

There is another one-way check valve right behind the glad hands.

And there's a couple more one-way checks behind the service and wet tanks.

Replace them ALL. They are cheap off-the-shelf Haldex parts that you can order at NAPA.

Where are you sourcing compressors/heads nowadays?

Mine was worse - punched a hole in a piston.

Ebay, surplus channels and surplus truck/parts dealers, Napa, FleetPride, etc. I got a good used compressor for $160 on ebay and rebuilt the head and then rebuilt my original head to carry for a spare.

It's all off-the-shelf Haldex parts.

My piston seem to have survived.

Thank you all, you saved me from a bigger damage!
My LMTV have 50000 miles, air system without big leaks. But anyway I discovered a broken spring:

I doubt the the new springs will survive forever, so my question is: after how many miles it should be rebuild again?
