2007 Toyota Yaris Parts Questions & Experts Answers

• Q: How do you service and repair the front lower suspension arm on the RH side on 2007 Toyota Yaris?

  A: The repair process for the RH side front lower suspension arm starts with disconnecting the battery cable and then proceeding to remove the hood sub-assembly and front wiper arm head cap before taking out the left and right front wiper arm and blade assemblies. The service requires removal of the hood to cowl top seal and cowl top ventilator louver LH part for hatchbacks and complete removal of cowl side ventilator sub-assemblies LH and RH and front air shutter seal for sedans. Start by placing wheels in a straight-ahead position while removing the front wheel before you can discard the outer cowl top panel. The maintenance starts with removing the column hole cover silencer sheet followed by the steering sliding yoke sub-assembly and steering column hole cover sub-assembly before separating the tie rod end sub-assemblies LH and RH and removing the front lower suspension arms and front stabilizer link assemblies. Suspend the engine assembly and remove the front suspension crossmember sub-assembly before taking out the front lower suspension arm RH by removing its bolt. Before installing the nut on the front lower suspension arm inspect its ball joint stud by turning it five times while using a torque wrench to measure torque on the fifth turn within 0.78 to 3.43 N m. Look for both cracks and grease leakage inside the ball joint dust cover. The procedure starts with temporarily securing the front lower suspension arm RH before placing the front suspension crossmember sub-assembly and proceeding with the installation of the front stabilizer link assemblies LH and RH followed by the front lower suspension arms LH and RH. The installation requires combination of the tie rod end sub-assemblies LH and RH with the steering column hole cover sub-assembly and steering sliding yoke sub-assembly and column hole cover silencer sheet. The front wheel received a 103 N m torque before the vehicle wheels were set straight ahead. The suspension became stable after lowering the car then bouncing it. Both bolts A and B received 137 N m and 160 N m torque settings to fully tighten the front lower suspension arm RH. The assembly process requires installation of the cowl top outer panel followed by cowl to register duct units for hatchbacks and front air shutter seals for sedans and front wiper components and cowl top ventilator louver elements for hatchbacks and the complete cowl top ventilator louver sub-assembly. Installation includes the hood to cowl top seal for hatchbacks as well as cowl side ventilator sub-assemblies LH and RH for sedans together with front wiper arm and blade assemblies LH and RH, the front wiper arm head cap, hood inspection and adjustment for hatchbacks followed by negative battery cable connection with 5.4 N m torque and front wheel alignment inspection.
