On a 2019 Ranger with jerking at low speeds: First I had the TSB done which did nothing to fix the problem. Two days ago I bit the bullet and had the DPFE changed and that seems to have fixed the problem . The technician wrote that there was moisture in the part.
This is for everyone’s information. I have a 2019 Ranger with about 22000 miles on it. The attached photo shows damage to the driver door rubber door gasket. This truck lives a pampered life: no off-roading and not a work truck. An easy fix but the dealer is claiming it’s not under warranty...
