Hi guys,

I noticed my front suspension drops overnight, and I'd start with cleaning the valve blocks, didnt really find any DIYs of removing the valve block. So I ll ask here.

1. Do I need to remove front wheels to let the suspension hanging free, or it doesn't matter if the wheels are on the car or not?
2. I persume the process is just removing the 3 air lines slowly and take it out?
3. Do I need to unplug the battery or pull out fuse F26E?
4. What should I do after replacing it to re-pressurize the system?

Much appreciated!

 

I replaced mine recently. Removed the right front wheel and let the suspension hang on the strut. I slowly disconnected the airlines to de-pressurize. I did not unplug the battery of pull a fuse. I put it all back together and dropped the truck back on the ground.

Started it up and let the compressor run for a few minutes. Before it posted any warnings, I turned the truck off and let it cool for 10 minutes. The 2nd time I started it up it was back to normal.

 

Out of curiosity, did removing and CLEANING your Valve Block help and/or fix the issue? If so, how did you go about cleaning it? I'd be curious to try this before actually replacing the unit.
