When driving my '19 Expedition 4x4 without a trailer, all tire pressures are stable. After attaching my dual axle Featherlite car hauler that's loaded (5000 lbs total weight,) the driver's side rear tire of the Expedition jumps from 39 Psi to 59 Psi. This just started happening after the trailer sat for a year. The trailer tire pressures remain normal.
The brake controller is set to 6 and seems fine. I don't see anything obviously wrong with the disks and drums on the truck and trailer.
I'm leaning toward sticking shoes on the trailer as the cause.
Any troubleshooting suggestions would be appreciated before I start tearing things apart.
Thank you.
