>> C << Driveshaft Nut Installation

WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Do not apply the vehicle weight on the front wheel hub assembly before fully tightening the driveshaft nut. Otherwise, the wheel bearing may be broken.

Check the hub seated surface for damage or corrosion. Whenever solvent is used for removing the corrosion, the surface should be degreased.
Check that the new driveshaft nut can be turned smoothly by hand. Then tighten it until it is seated.
Using special tool front hub and flange yoke holder (MB990767), tighten the driveshaft nut.
Tightening torque: 270 ± 27 N.m (199 ± 19 ft-lb)
After tightening to the specified torque, check that the nut is seated securely.
