An adjustable support assembly for an aircraft leading edge guide track. The support assembly includes an upper portion pivotally connected to the guide track, and a threaded shaft having a rotatable member threadably engaged thereto which extends through the top of a trunnion housing. The rotatable member includes a shoulder portion which is disposed beneath the trunnion housing, and which is engaged by a wedge member therebelow to support the slat track via the shaft. Rotation of the rotatable member along the shaft adjusts the height of the guide track. The wedge member is supported by a horizontal shaft connected to the aircraft wing and to the housing. The wedge member includes opposing side portions which extend downwardly and inwardly, and which are engaged by complementary surfaces of locking tubes disposed about the horizontal shaft. The locking tubes are adapted for inward movement against the wedge member to cause upward movement of the wedge member against the rotatable member to sandwich the rotatable member against the housing to prevent unwanted rotation.
