00 Expedition Clicking while driving

[Roosterj69]

Hello! New guy here. My 00 xlt 4x4 is clicking when driving forward but goes away on turning. I can feel the rhythmic clicking through the brake pedal. I engaged 4H and it went away forwards but the clicking and a grind started in the turn. Any ideas?

Probably the front axle disconnect shift fork. That is a known failure point on those.

Got a new code reader and its showing P1820 and P1828. Also C1107.

Those are transfer case relay codes for the electric shift. I thought your Expedition had a front axle central disconnect like an f150. Look at Lemon-manuals.la for manuals. They are helpful, C1107 is a front wheel speed sensor code. Jack it up and spin the front wheels, look for bearing looseness.
