The timing on this thread is awesome. My 07 has no shock absorption after a bump in the road or after going over a speed bump. I'm not mechanically inclined so I work with a local shop. For the most part I used a Toyota dealer but they have become more interested in getting their commissions than actually working with me on what needs to be done. With that said, would you all suggest shocks, etc or should I look into something else. Sorry to highjack this stream of info but you all really seem to have a handle on this issue. Thanks in advance.
Do you have AHC or conventional? For AHC, it's impossible to diagnose without knowing the "health" of the system. You'd need Techstream or an iCarSoft TYT reader to get the pressures. One thing you could do would be to run a graduation test. Don't need any tools for that.
Put vehicle in Low. Once rig settles and stops moving, pop hood and observe the AHC reservoir (passenger side firewall in engine bay). There are "graduation" marks on the reservoir. Take note of what mark the fluid is at. Shut the hood, return to the driver seat and cycle the AHC to Neutral/Normal. Once it settles and stops moving, pop hood and observe the AHC reservoir again. Take not of what mark the fluid is now at. If the total difference in marks between the two settings less than 8, you're looking at a compromised system. 14 marks would be brand new. Most consider "healthy" to be 9-11 marks.
