Sorry for the delay! Back after a nice Independence Day weekend with bounce test results...
First I need to get it straight as to whether or not we have struts or shocks in the rear of our cars. I have a 98 Bonneville SE (pictured below), with no electronic suspension, air shocks or computer command ride (at least there are no buttons in my car for that)
I really got the rear of the car bouncing, the struts/shocks were making a little bit of noise, like a regular shock absorber (or strong arm) does. I let go on the down motion on the 10th bounce, it bounces back up and then sqauts down about 2 inches. I can get a good 8 inches of play in the rear when I do quite a few bounces.
Can someone point me in the right direction? Also, if it'* not the struts/shocks, what could it be? If it is the struts/shocks, what brand is a good brand to replace with? I have a very high opinion when it comes to using stock parts, but if there are better suspension components (and I would imagine there would be in this case), which ones should I use?
Thanks everyone once again!
