Be sure to start with the service procedures as if replacing an upper or lower transverse link, which begins with a measurement of the vehicle's curb
height. For example, as found in ELSA Web> Repair Manual> Chassis> Suspension, Wheels, Steering > Front Suspension> Removal and
Installation > Upper Transverse Link with Retaining Bracket As explained in ELSA Web, it is essential to simulate the curb height when
reassembling the suspension links with bonded rubber bushings.
For vehicles outside of warranty, create a TAC ticket and attach clear digital photos for assessment of the concern and additional instruction.
After review, the new axle components may be installed. The additional parts needed due to service part supersession, may be covered under
