2. After removing the rivet, verify the noise came from this location by pounding a wedge between the crossmember and the frame liner, then driving the vehicle to reproduce the noise. The wedge will lift the crossmember off of the inner frame liner and eliminate any noise if the lower left front #1 crossmember joint is the source of the noise.
3. With the wedge still in place, insert the Bearing Strip (F6TZ-5D033-BA) between the #1 crossmember and frame liner. Align the strip approximately centered and extending well past the hole location. Remove the wedge and drill a 11.113mm (7/16") diameter hole through the bearing strip.
4. Line ream the existing hole through the liner, frame flange and crossmember to 14.288mm (9/16") (Figure 5). Remove any burrs after reaming.
NOTE:
TO PROPERLY REAM THE HOLE ON A VEHICLE WITH LEAF SPRINGS, THE SPRING MUST BE REMOVED TO PROVIDE VERTICAL ACCESS TO THE RIVET HOLE.
