The mileage on my 2008 Chevy HHR LS is as shown in the picture. Today, I replaced the rear shocks. This means that the car now has new struts and shocks all the way around. The rear shocks are MacPherson style and are separate from their struts.

The job required jacking the car up in the the center of the rear axle. Because the lift on the car is only 6", I ended up having to jack up the rear driver's side area with a 2 Ton scissor jack, the get the center of the axle of the with the 3 Ton floor jack. The Chilton's manual for this model noted that there was a jacking spot in this area. Personally, I would have preferred the floor jack that they have at Harbor Freight Tools that has a plate on it. Because around the axle was a piece of angle iron. My round plate would never make contact with the axle, so I had to jack on the angle iron.

Once I got the jack stands in place, I dropped the axle enough to remove the lower mounting bolts for both rear struts. Then I released all the pressure from the floor jack and let the axle drop as low as it could go.

This job eluded me when I was at home port last. For some reason, I was unable to lift the springs out. But this time, I figured it out. The spring in question has to be grabbed down at the top. The upper shock tower is sitting on a peg and needs to clear it for disassembly.  Well, with the brake line in place, it makes is hard to do that. In fact, I've heard of some disassembly instructions call for removing the brake lines. If I ever get anything bigger in there, I certain that I'll have to.

I was concerned when I compared my old shocks with their replacements.  The coils on the old ones wrapped around the upper shock towers. The new ones dont come so close. And the new ones are longer. I consulted with a friend on Facebook about whether they'll coil around the towers in time and he says no. That's ok, it's merely consistent with having bought heavy duty shocks and struts. Which now means that my rear shocks now have an extra coil. And that's excellent for hauling my trailer.

I did the work in my brother's driveway. After I was done, I put the car on the ground and immediately coupled my Harbor Freight 4x8 Utility Hauling Trailer.  And I was disappointed to note that the trailer is well below the HHR's 1,000lb towing capacity and the car still sunk down like it always had before today's servicing :-(. At least I know now that it's normal.

After I got the trailer to home port and uncoupled it, I took the car for a drive and noticed that my previous issues of driving around curves that hook with 20 & 25MPH advisories didn't feel like I was going to flip the car anymore. I'm glad to say that I solved that problem today. I can't wait to see its improvements in Southern Ohio on 03 October when I leave for Basecamp F at Scioto Trail State Park.

Lastly, the driver's side rear drum that I had to mount tightly is whistling and burning the shoes to the point that I can smell it. I expected this and hope that since the shoes are newer, that they'll just burn themselves free. The next time that I replace those, I'll just replace the shoes and rotary (again).
