7.
Using a 1/8 inch drill bit, drill a hole through the center of each of the two holes which remain on the portion of the bracket which is still
connected to the frame rail (See Figure 2- "Identification Holes"). Drill all the way through the frame rail for each hole. These holes will be used
to locate the replacement bracket later.
8.
Using an air chisel, roughly chisel off the remaining portion of the bracket still attached to the frame rail.
Note:
The use of a torch to remove the bracket is not recommended. The use of a torch may damage the material properties of the frame resulting in
reduced strength.
9.
After removing the majority of the bracket from the frame rail, a grinder should be used to remove any excess which remains.
10.
Position the new bracket by aligning the holes with the "identification holes drilled in the frame rail in Step 7. Note that the lower hole on the
replacement bracket may have to be drilled out in order to see the hole in the frame.
11.
Once the bracket is positioned correctly on the frame, install an appropriately sized temporary screw and washer combination through the top hole
on the frame bracket and through the identification hole which was drilled in Step 7. Tighten until the bracket is flush against.the frame and no
longer needs to be held in the correct position by hand.
12.
Temporarily install the shock into position by installing the bolts at the lower control arm and at the shock bracket. Compare the position of the
shock and shock bracket with the corresponding parts on the other side of the vehicle. Make adjustments if necessary.
13.
In preparation for welding, cover the fuel vapor lines and brake lines behind the upper shock bracket with a metal shield. Also, ensure that other
components are protected as suggested in step 6.
14.
With the shock and shock bracket still in position, tack weld the fore and aft sides of the bracket.
