The factory manual states that there are 7 welds per side on the rear crossmember. It also states to remove the rear body mount bolts & loosen all others to lift the body for access.


Here are the steps from the FSM:


Mount the vehicle on appropriate frame correction equipment (“frame rack”) and using a three-dimensional measuring system measure frame/body and correct to vehicle specifications.



Remove rear bumper components.


Remove hitch receiver or tow hook if equipped


Release rear body mount fasteners, and loosen remaining body fasteners to allow lifting the body upward providing work access


Using a reciprocating saw, or equivalent, cut the crossmember close to the welds to the side rails and body mount brackets (1) and remove (each side of crossmember has a total of 7 welds).



Using an angle grinder, grind off remaining crossmember and weldments.



Dress new crossmember at weld locations so that a very shallow bevel is created and remove any e-coat, inside and out, on replacement part within 25.4 mm (1”) of weld zones as best possible.



Refer to the weld chart for proper weld rod and approximate welder settings, then using the old crossmember adjust the welder to create a proper weld bead.


Install the crossmember and locate using three-dimensional measuring equipment.


When proper, tack-weld crossmember securely in position (1).



Complete weld installation of crossmember ensuring proper weld penetration.



Clean welded area of any burned coatings or spatter.



Apply refinish materials to exterior of crossmember and side rails (2) to restore appearance and corrosion protection.


Apply inner panel anti-corrosion material inside crossmember.



Install the rear body mount fasteners and tighten all fasteners.


Install hitch receiver/tow hook.


Install bumper components..
