• Q: How to service and repair the front lower Control Arm on 2007 Toyota Corolla?

  A: Begin repairs or services of the front lower suspension arm by removing the front wheel before breaking the front stabilizer link assembly from both left-hand (LH) and right-hand (RH) sides. Perform procedures for both sides identically. Move on to the front suspension arm sub-assembly lower No. 1 LH by unbolt and unscrew the two nuts from the lower ball joint assembly front LH before performing the same operation for the right side. Use four bolts to divide the rack & pinion power steering gear assembly but only loosen one bolt since rotating the nut is impossible before suspending the assembly. The procedure entails suspending the engine assembly before isolating the front suspension crossmember sub-assembly by removing three bolts and three nuts to detach the transverse engine mounting insulator and engine mounting member sub-assembly center and finally removing four additional bolts from the transmission jack to drop the crossmember. Unfasten two suspension arm lower sub-assembly screws and one nut to remove the No. 1 LH component. Installation process begins by temporarily tightening the front suspension arm sub-assembly lower No. 1 LH then with the aid of a transmission jack the front suspension crossmember sub-assembly can be lifted before inserting Special Service Tool: 09670-00010 into both sides base holes to properly sequence bolt tightening. Both Bolt A and Bolt B undergo installation torque of 157 Nm (1,601 kgf-cm, 116 ft. lbs.) and 113 Nm (1,152 kgf-cm, 83 ft. lbs.) respectively. Afterward, install three bolts and three nuts with 52 Nm (530 kgf-cm, 38 ft. lbs.) torque to complete the reconnection of transverse engine mounting insulator and engine mounting member sub-assembly center. You must first install the rack & pinion power steering gear assembly with its four bolts tightened to 58 Nm (591 kgf-cm, 43 ft. lbs.) after which you must install the front suspension arm sub-assembly lower No. 1 LH with two nuts and a bolt at 89 Nm (908 kgf-cm, 66 ft. lbs.). The second step involves installing both front stabilizer link assemblies after completing the procedures for the RH side. Tighten the vehicle suspension with the front wheels on and the vehicle lowered while bouncing it several times. To complete installation tighten both bolts and the nut of the front suspension arm sub-assembly lower No. 1 LH all the way to 137 Nm (1,397 kgf-cm, 101 ft. lbs.). Ensure to tighten the bolt when the nut cannot be rotated because it is the last step before inspecting and making a front wheel alignment.
