FAQ for Exhaust Resonator Repair
Q: What is the resonator installation procedure?
A:
First, lubricate the insulators, and install the muffler and the resonator assembly. Next, install the insulators to the exhaust system hangers and install the catalytic muffler to the bolt. Tighten the nuts to 45 Nm and install the right rear shock absorber lower bolt/nut. Tighten the bolt/nut to 65 Nm. After that install the right rear axle tie rod bolt/nut and tighten the bolt/nut to 105 Nm.
