Leveling valve

Is it just the new normal for these to go bad after about a year or so? I never had one go bad as a company driver in about 9 years. On my truck in the past six years I have replaced it a half a dozen times. I remember one time right out of the box a brand new haldex was leaking down. These are all made in Mexico. I think that is the only option anymore aside from Chinese.

 

Installed correctly yes. If it is crud in the system why only the level valve and none of the other control valves? I did recently have a very minor amount of oil in some moisture when I purge my air tanks but really not a lot. And that doesn't explain all the ones that prematurely went bad in year's prior.

 

Last time I replaced the rod with the level valve.

 

He could be. I guess I'll take the old one apart as best I can and see if there is any crud or rust flakes or something inside of it.
