- Installation tips
Installation seems straightforward just requires time and work:
- remove bolts and clips from under cover w/ 12mm socket wrench.
- Remove Cross member support plate flange bolts (2 bolts)
- If equipped with support arm front, remove (4 flange bolts).
- If no front support arms, remove 4 flange bolts on cross member support plate.
- w/ front support arm: use new long flange bolts to loosely secure the front support arms and flexible lower arm bar with pillow ball bolt facing outwards and cross member support plate.
- Tighten center bolt that secures the front support arm.
- Without front support arms; use flange bolts short to secure flexible lower arm bar with cross member support plate (tighten to 60Nm (6.0Kg f-m) using 14mm socket wrench and torque wrench)
- Tighten the self-locking nut that temporarily fastens the pillow ball bolt and bracket on the left side of the bar. (Tightening torque: 35N m (35Kg f+m)
- The bar should rotate smoothly.
