Apparatus for retaining a joint of an endless track for a crawler-type vehicle is provided which includes a metal preform which is pressed into a retainer cavity surrounding and located at each of the ends of the joint of the track. The cavities are cooperatively formed by a pin groove in the opposite end portions of the pin and a link socket in the respective link outboard end portions and which are disposed in registry with the pin grooves. Once intruded into the cavities, the formed-in-place retainers thereby provided virtually eliminate any end play in the joint during operation of the crawler vehicle.
