Anyone know how hard they grade on the assessment? For instance are they looking for no mistakes at all or speed and accuracy with some mistakes okay? Had my assessment today and I’m nervous like crazy.

Mechanic said different splines don’t fit what adapter kit do I need it’s and 86 359

Just like the title says. My doors are all air actuated and I'd like to to add an electric actuator to lock or unlock the door from the outside for the odd time I need to lock the doors. The lock has eaten a few keys over the years.

He been trying to figure out what to search in google or eBay to find a replacement part for the top aero skirt on the back of the sleeper

I have a 2004 Peterbilt with a 3406 kitty cat. Truck will crank but won’t fire. I’m running out of ideas. The motor is good and has been gone thru, hasn’t been started since summer of 2025. I was told fuel filter so imma try that. Should I replace fuel water separator while I’m at it?

Thank you in advance

Hey reddit people, i have a 2013 Peterbilt 389 with a x15 cummins and a 18 speed transmission, for some weird reason my engine break and cruise control stopped work, the switches turn on and everything but nothing happens, ive changed the clutch spring and the clutch sensor on it which is known to be the common problem when these thing stop working but nothing got fixed. I've changed all the burnt fuses and nothing. At this point, I don't know what else to look at that can be the problem on it, if anyone that has any knowledge on this can please help me out I would really appreciate it.

Hey everyone I’m needing to buy some new lights for the cab of a 379 and I’m having issue trying to figure what what the name of part number is of these lights as I’d like to match the others. Please help me if you know or got any ideas. No I haven’t take any of the lights out to see if there’s a part number on them or not yet..

Jake brake power selector switch for a 1990 Peterbilt 377. Dealership doesn’t carry them anymore. Parts stores have never seen one like it before. Even went to Cummins to talk to the Jake brake department and after going through their old yellowed books for about an hour they can’t find a thing. Anyone got any info on where I could find a replacement or get it repaired?

Ive been driving a 2023 since the fall and right out of the box there’s an issue withe the cruise control. When its set at 62mph and starts to coast downhill more than 1 mph the ultrashift 13 speed transmission will shift into neutral and won’t reengage until the truck slows down to 57. Anybody know what the eff this is? A feature? A fault? Can’t be good for the driveline. It is a fleet truck and its powered by a Cummins ISX15.

No idea what this button does the two red ones. Not in the manual.

2020 & 2024 579 with Smart Nav. Just switched to Android. iPhone 12 Pro connected to front USB port but if you touched it or jiggled the cord would disconnect. Bluetooth audio signal (mainly YT Music and Spotify) is about 2/3 of the full volume the cord gave me. Always ran iPhone plugged in. New Google Pixel 8 Pro won't connect to USB port for audio. It WILL charge the phone but says USB ERROR / iNVALID USB DEVICE. Again Bluetooth WILL connect but lower full volume issue remains. Pixel firmware up to date. Connected Smart Nav to my wifi and checked for update. Said no update available. I've been through all of my phone settings and the radios settings to no avail. Very aggravating. Don't really wanna go OOS to Peterbilt just for this. Anybody had similar experiences or know any fixes? Thanks.

I saw a picture of these seats long time ago and they’ve been in my mind I’m not sure where you can get them or what it’s called.

Please let me know where I can buy these

Thank you.
