My 99 q45t

[doc7592]

Hi,I have a ? that I'am sure has been asked before. My rear shade has stopped working, is there a replacement motor or rebuild for, and how do you get to it.Also at about 90 mph with suspensio in sport mode i get vibration that feels like it's coming from right front tire.

How do i know if the active suspension needs repair.

Is it a difference between the active system in the q45a vs q45t?

1.) My rear shade has stopped working, is there a replacement motor or rebuild for, and how do you get to it.

2.) Also at about 90 mph with suspensio in sport mode i get vibration that feels like it's coming from right front tire.

3.) How do i know if the active suspension needs repair.

4.) Is it a difference between the active system in the q45a vs q45t?

1.) Yes, call the dealer (you really don't want to know). Get an FSM (and TSB while when downloading the FSM). Probably bent. Check it out very carefully.

2.) Road force balance it. http://www.gsp9700.com/

3.) You don't have an active suspension. Just electronically switched valves. They wear like any shock absorber. Usually gone between 80K and 100K miles. Hope you have a big piggy bank if you need to replace them.

4.) Yes, the G50 is semi active, the FY33 is not active at all.

Do a little reading of the previous posts.

FSM = Factory Service Manual

TSB = Technical Service Bulletin

The valves are internal to the shock absorber/struts and not sold separately. They are not what wears.
