	then lower the car until the weight is carried on the jack. 4. Remove cotterpins and nuts from the lower control arm shaft bracket bolts. Drive out the bolts and insert a long drift punch to maintain alignment. Fig. 4. 5. Raise the car slowly with the chain hoist to remove the spring pressure. Then remove the stand jack. This allows the lower control arms and spring seat to drop down, releasing the spring. Installation 1. When installing a front spring, make sure the ground end of the spring is up and that the lower end coil of the spring seats in the recess in the lower spring seat. 2. Raise the lower control arms and spring seat and place a stand jack under the inner end.	LOWER CONTROL ARM PIVOT PIN AND BUSHING Disassembly 1. Raise the car and place a stand jack under the inner side of the lower spring seat. 2. Remove the wheel and tire assembly. 3. Using a 1" socket wrench, remove the lower pivot pin from the support arms and knuckle support. A. Turn the wheel being worked on to the extreme outward position. This locks the knuckle support so that it cannot move outward at the bottom when removing the bushing. 5. Using a 1-1/8" socket wrench, remove the lower pivot pin bushing from the knuckle support, Fig. 5. Reassembly 1. Install the lower pivot bushing and tighten it firmly in the knuckle support.


		Fig. 5—Removing Lower Pivot Pin Bushing Before starting the lower pivot pin, place a new Neoprene seal around the front lower control arm and another new seal over the exposed end of the lower pivot pin bushing in the knuckle support at the rear, as shown in Figure 6. This prevents damaging the seals during assembly. Now start the new pivot pin into the front lower control arm. Hold the knuckle support in the center of the yoke formed by the lower control arms and thread the pivot pin into the bushing in the knuckle support, being very careful to keep it centered in the yoke.

Bolt the pivot shaft brackets securely to the cross member and install cotter pins. 5. Raise the car to remove the stand jack. 6. Lower the car to the floor and connect the stabilizer link to the spring seat.
