My 2019 Kenworth has a Holland fifth wheel and every now and then I will have to mess with it sometimes as long as an hour to get it to release. It was really bad when I first got the truck went to the shop and they put some kind of spring machine on it I guess to loosen it up? I keep it lubricated with spray, and 95% of the time it works just fine. Went did a drop and hook the other day and I could not get it to release. I think I know all the tricks, make sure you back up take the pressure off, I've even used the dollies to take the weight off. But the damn thing releases when it wants to. I fought with it for over an hour went and sat in the truck to cool down as it was over a hundred degrees on the cement . Went back out and it released on the first try? One time I was at a Walmart DC during a downpour. When you live unload there you're supposed to Dolly down, unhook and pull out from under your trailer. Fought with it for 45 minutes finally went in and talk to the safety guy and he let me stay attached. Went back out to the truck and thought I'll try it one more time and I'll be... It released... after I was soaking wet. Any suggestions other than it's possessed? I really love my truck other than this issue. Every time I have to release it I pray... usually the big guy answers...

Drop And Hook:

Drop and hook means the driver will drop one trailer and hook to another one.

In order to speed up the pickup and delivery process a driver may be instructed to drop their empty trailer and hook to one that is already loaded, or drop their loaded trailer and hook to one that is already empty. That way the driver will not have to wait for a trailer to be loaded or unloaded.


When a violation by either a driver or company is confirmed, an out-of-service order removes either the driver or the vehicle from the roadway until the violation is corrected.

Doesn't it have a button in the cab? Our 2018 Kenworth daycab has one. It's under a red cover button that you lift up, then there is a little lever you lift up. Releases it Everytime, noticed it was tough to pull when doing it manually.

Thank you brother the button is hidden behind the Qualcomm. It does lift up so I'm going to try that next time. I'm surprised the guy at the shop didn't say anything about that?thank-you.gifthank-you-2.gifconfused.gifembarrassed.gifdancing-banana.gifdancing-dog.gif


Omnitracs (a.k.a. Qualcomm) is a satellite-based messaging system with built-in GPS capabilities built by Qualcomm. It has a small computer screen and keyboard and is tied into the truck’s computer. It allows trucking companies to track where the driver is at, monitor the truck, and send and receive messages with the driver – similar to email.

This is one of those feel good success threads on TT.

Of course, I don’t have a KW, just a lowly Frightliner. The only button we have is the ejection seat button. I’ve been tempted to use it many times.

Our new bid runs start next week, I hope I am assigned a Freightliner I have a 2019 Kenworth but i found the Freightliner to be more comfortable and driveable. But a lot of that has to do with the way OD specs the trucks.

So I just got done switching a load and I still couldn't get the fifth wheel unhooked... I did the switch when it didn't release... Gladhand I don't know what's going on with this fifth wheel? I was trying to release it before he got here he called me head of time. Again I tried everything... the way we got it on hooked I dropped my airbags and as they were going down he got it unhooked. Crazy thing is this is two straight times this has happened. Just watch the next unhooks will go without a problem... I'm out of ideas

Might be out of adjustment, might need grease, could be that it was ****ed or had uneven pressure on it, etc. I usually spray mine every two weeks with a spray bottle of diesel fuel, or from an aerosol can of Howe’s penetrating lube. Don’t be afraid to spray a LOT of fluid on there. Try that and get back to us with your results.

I spray it with a lubricant every time I unpack all over the damn thing. Hopefully I get back to the terminal soon... So I can get it looked at again. But I swear it's possessed. Like I said it will work fine the next 10 times I unhook it.


A facility where trucking companies operate out of, or their "home base" if you will. A lot of major companies have multiple terminals around the country which usually consist of the main office building, a drop lot for trailers, and sometimes a repair shop and wash facilities.

Damn voice texting meant to say I spray it everytime I unhook it.

I think you said in another thread that you got it checked out, but it sounds like you need it checked again. It's ridiculous to have to spend an hour getting it to release. Also if it's not working right it could be dangerous.

I notice that twice it released right away after waiting some time. That makes me wonder if it could somehow be air pressure related. Does the air pressure hold when you're parked? Maybe you could try pumping the brakes to reduce the air pressure before pulling the releae. It's a long shot, don't know why air pressure would have anything to do with it except that it does have an air release button, but it's a thought.


Transportation Worker Identification Credential

Truck drivers who regularly pick up from or deliver to the shipping ports will often be required to carry a TWIC card.

Your TWIC is a tamper-resistant biometric card which acts as both your identification in secure areas, as well as an indicator of you having passed the necessary security clearance. TWIC cards are valid for five years. The issuance of TWIC cards is overseen by the Transportation Security Administration and the Department of Homeland Security.
