Service Procedure

The steps below will add an additional weld to eliminate the possibility of the barrel nut creak/pop noise.

1. Attach Rotunda Wireless Chassis Ears JSP97202 or equivalent to the subframe. Does diagnosis with the chassis ears indicate the noise is originating from the right front mounting bolt of the front subframe?

(1). Yes – proceed to Step 2.

(2). No – this article does not apply. Refer to Workshop Manual (WSM), Section 100-04 for normal diagnostics.

2. Disconnect the negative battery cable. Refer to WSM, Section 414-01.

3. Remove the right front wheel and tire assembly. Refer to WSM, Section 204-04.

5. Locate the front subframe bolt mounting tower bracket on the right side frame member and mark 2 cut lines approximately 63 mm (2.50 in) long as shown. (Figure 1)

Figure 1

6. Using an abrasive cut off wheel, cut the bracket sheet metal along the marked lines. (Figure 2)

(1). Make sure to only cut through the outer layer.
