drilling, be very careful not to drill through the plastic
cover into the wire harness.

2. Place the black mounting castings in the open ends of the

tube. Line up the holes and securely fasten the castings to
the tube with hardware provided. See Detail A.

3. Assemble the Mounting Feet to the step as shown in the Master drawing, but only hand tighten.

4. Take only two steel brackets with the hardware provided (be sure only to use the 5/16" bolts

provided) and bolt each steel bracket to each mounting foot. Tap each steel bracket into position
until the steel brackets are straight on each mounting foot. (Refer to diagram 2)

5. On the passenger side only, there are air-conditioning

lines and rear heater lines on the bottom inside face of
the rocker panel that run along the length of both doors.
(Refer to diagram 3). There are four rubber clamping
brackets that hold all four lines in place. Take a 10mm
socket and

6. From underneath your vehicle, place your step in desired position with the feet of the steel brackets

laying on top of the pinch weld. You may have to slightly move your step forward or backward to
avoid the rubber clamping brackets and the front body mount.

7. While securely holding the step in place, mark the top hole of each steel bracket and mark lines all

along each side of the steel bracket on the body metal. Remove the step from underneath the
vehicle.

8. Center-punch the two top marked holes. (REFER TO THE ELECTRICAL CAUTION ABOVE!)

Take a drill motor and a sharp 1/8" drill bit and drill out the center punched holes. Go back with a
sharp 5/16" drill bit and enlarge the 1/8" holes. (Caution: do not allow the drill to wander when
drilling. This will result in a mis-alignment of the drilled holes.)

9. *Take an unused steel bracket and place in the same spot as where the drilled hole and lines are.

10. Put one of the 5/16“ bolts through the body metal from

the open door side and through the steel bracket. Line

up the bracket with the marked lines. Mark two more
lines on the outside of the pinch weld that line up with
the lines inside of the pinch weld. Also, using the edge
of the pinch weld as a guide, mark another line across
the bottom of the foot of the steel bracket (refer to
diagram 4).

11. Take the 5/16 bolt out and remove the steel bracket.

Measure the distance from the marked line across the

foot of the steel bracket and the center of the hole.

12. Take the dimension from step 10 and measure the same distance from the pinch weld. Mark a line

on the body metal centered between the other outside lines.

13. Measure across the outside lines and mark another line that will cross the line you marked in Step

11.

14. Center punch where the lines cross.

15. Stuff a rag between the body metal and the A/C and rear heater lines to push the lines up out of the

way while drilling.

16. Before drilling, take the steel bracket and slip it between the body metal and the A/C and rear

heater lines for protection when drilling.

17. With a sharp 1/8" drill bit, drill out the center punched area. Go back and drill out the 1/8" hole

with a 5/16" drill bit.

18. Place the steel bracket back into place. Put a 5/16" bolt in both holes to see if the holes in the body

metal line up with the holes in the steel bracket. If the holes do not line up, take a round file or a
power grinder and enlarge the hole until the bolts fit.

19. Repeat the steps for drilling out the holes for the other

steel bracket.

20. With all the holes drilled, place your step back into

position. Use the 5/16" hardware provided and hand
tighten the front steel bracket to the vehicle. (Refer to
Diagram 5).

21. Take additional hardware and hand tighten the rear

steel bracket to the vehicle. NOTE: (if the rear bracket
holes do not line up, loosen the bolts on mounting
foot. This should give enough play to get the holes to
line up.)

22. With everything in its proper place, go back and

securely tighten all the hardware.

23. Remove the rags used for drilling.

24. Tighten the loosened screws on the rubber clamps for the A/C and rear heater lines.

25. *Follow the same steps for installing the other step on the driver’s side of the vehicle. However,

since there are none, skip over all directions that refer to A/C and rear heater lines. *Also, after
