Rear Wheel Hub Torque Specs
The HHR rear wheel hub is held to the vehicle much like the front wheel hubs. There are 4 bolts which torque into nuts that
hold the hub onto the rear wheel suspension. To remove these bolts and the hub assembly you will first need to jack up the vehicle and
remove the braking system from the corresponding side of the vehicle. Once out of the way you can remove the bolts by using the access
holes on the hub plate itself. Be sure to hold the nuts on the other end with a wrench. Once all 4 have been removed you can then remove
the rear hub assembly and place a new part into its place. The 4 bolts can be torqued down to 44 ft-lbs.

Rear Shocks Installation
To replace the rear shocks on a Chevy HHR you will need to remove two sets of bolts/nuts located at the bottom
and top of the shock. Both of these fasteners can be accessed from underneath the vehicle by jacking it up and removing the
wheel. There is a single nut that will need to be removed from the inside of the trunk.
To uninstall the old shock simply just remove both of the fasteners sets and the part will come out. When installing the new
part reverse the procedure and tighten up the lower bolt to 55 ft-lbs and then the upper bolts and single nut to 25 ft-lbs.
