Spread axle dump valve switch help?

500k. Just had the pads changed, although mechanic said they still had life in them... Hendrickson disc brake pad kit was $250 per axle plus labor. Not to bad....

 

Uh, I'm not totally following... My 2019 trailer purchased new in 18 had the standard 7 way along with a 4 way for the dump axle and lift. I had a spare 7 way in the box so instead of purchasing another 4 way plug and wire I had the dealer remove it and throw a 7 way in... free of charge...

The dump valve wire is wired directly into the 7 way which use to be a 4 way...

I have a 2020 peterbilt 389 so the auxiliary switch that you wire the secondary 7 way into just needs a fuse plugged in to activate the switch and then everything is supposed to be g2g... obviously not. I've been busy so haven't had a chance to crawl under the trailer and check the actual dump valve...after all haven't had a dump valve hooked up in 4 years...

With the current load and rates situation I been getting out of my comfort zones doing questionable loads ( probably like most ), after tearing chunks out of my steer tire last week on one of those loads that you couldn't back a Toyota prius into, I decided it's time to reactivate the dump valve before the driver activates and blows up mentally at one of these places. Now you understand sir? I hope...

Update on the dump axle Coming soon. Seems every time I turn around something else is requiring my attention. 400k on peterbilt and squealing like a pig, so just picked up new pulley, tensioner, and belt today... shiny new steers last week replacing the michelin with 90k miles on them...

It never ends......


Just tried to purchase a new lock latch " peterbilt" specific and they wanting a whopping $450 for this latch...

Rolling with the bungie on my box is driving my nuts...

I'm ready 4 vacation. Coming soon!!!

 

Ya they claim $1600 for a new box, did some Google searching and came up with this, so gonna call them tomorrow. Seems a no brainer provided this price is current...

 

I'll call and post pictures of the latch tomorrow. It's in the shape of a S, so what you posted won't work. Thank you for posting it though. Much appreciated
