Removal of Suspension Arms with Sized Mounting Bolts
Rear Suspension Member:
1. Remove rear suspension member.
2. Avoiding the welded bead area, make 6 center punch marks on each side of the control arm as shown in Fig. 24. (Distance between punch marks will be about 8 mm).
Rubber Bushing:
3. Using punch marks for reference, drill holes into the rubber bushing using a 4 mm drill. Enlarge the holes using a 6.5 mm drill. Fig. 25.
Rear Suspension Arm Separation:
4. Use either an air chisel or a hand chisel, cut the area between the holes. Separate the rear suspension arm from the member. Fig. 26.
Bushing Removal:
5. Use an air chisel or hand chisel to remove the remaining portion of the bushing. Insert the chisel between rubber and collar to cut the remaining portion. Apply the chisel forcefully to turn the bushing so its cut-off surface is facing upward. Prying the chisel towards you, apply it forcefully downward to remove bushing. Fig. 27.
Remove the Nut:
6. Loosen and remove the nut. If the nut is seized and does not come loose, heat the nut using an oxyacetylene torch. Do not apply heat directly to the bracket or bolt. Fig. 28.
Remove the Collar:
7. Drive the bolt out to remove the collar.
Note: (1) For outer collar of bushing the bolt can be driven out easily by widening its slit with a chisel. Fig. 29.
Inner Collar of Bushing:
(2) For inner collar of bushing, the bolt can be driven out easily by heating the collar with an oxyacetylene torch. When heating the collar, avoid heating the bracket or bolt. Fig. 30.
When the rear control arm is removed from the rear suspension member using an oxyacetylene torch, the following anti-rust treatment should be performed.
8. Remove the bracket areas, oxidized film from heating, and mud from the rear suspension member outer surfaces with a wire brush and sandpaper.
9. Apply an even coat of undercoating P/N 00216-10000 with a paint brush to the area where rust or oxidized film were removed. Apply sufficient undercoating to ensure coverage of the bracket areas.
10. Install control arms to the suspension member.
11. Install suspension member to body.
12. Return to Step 3A.2.
