OK, the shocks have now been removed. The official shop manual calls for an elaborate procedure to drop the whole axle assembly after disconnecting the ABS assembly and removing the brake caliber and rotor. WTF? I simply placed a jack under the bottom of the shock to support it while I removed the bolt that passes through the bushing. Then I loosened the two nuts on the top shock absorber mounting bracket and pulled out the shock with easy as can be. The hardest part about removing the rear shocks was to remove all the interior stuff necessary to get to the shock mounting bracket.
So far, so good . . . Now its on to compressing the springs and replacing the shock and strut cartridges. BTW: At 100K miles the dust boots for both shocks and struts were totally ripped up. I had to special order these from the dealer (why these aren't commonly stocked parts I have no clue) at a cost of around $100 dollars. I bet that the service writer who quoted me a price to have the shocks and struts replaced by the dealer didn't include the boots. Bottom line: dealer quote for the job including parts and labor (with $100 added for the dust boots) was $1600 bucks! My actual cost for parts alone was $525. Wahooooooo!
