My Nissan Murano recently (about a few weeks ago) began bouncing pretty badly like a ball any time I go over a small bump or irregularity on the road. It began with feeling EVERY bump and crack on the road (no longer a smooth ride) when I got new tires installed. Then when it was time to rotate the tires, THAT'S when the bouncing began. A few times it almost bottomed out. I am the original owner, and have done primarily very local driving, I don't speed (nothing above 65) and even my commutes over the time I've had my Murano have been less than 20 miles. So I am not understanding why the struts/shocks are giving out now. If this is the problem.

How can I tell what the problem is and how much can I expect to pay (parts and service) to get it fixed?

Speed and driving style have nothing to do with how long struts last. If that were the case, I'd have gone through ten sets by now. My Grand Caravan has 251,000 miles, is 25 years old, and the struts are original. That isn't typical, but there is no typical time for struts and shock absorbers to fail or wear out.

Start by looking at the top of the strut body where the shaft comes out, and look for oil running down from there. That's a definite sign it's time to replace them. A bounce test will also usually show if they aren't dampening like they're supposed to. Even when there's no leakage, it is not uncommon to experience a bouncy ride after a long trip. Forcing the hydraulic oil through the tiny ports causes it to get pretty hot, and that makes it thin out and become less effective.

We don't get involved with costs here because there's way too many variables, but as a general guess, a pair of struts will cost around $100.00 per pair, less for domestic cars, and will take about an hour to replace. The car will need to be aligned after the struts are replaced.

WOW, this totally helps except I am not quite sure what a "bounce test" is or how it's done. However, now I know what to discuss when taking it to a service center. Thank you so much.

The bounce test is to push down on one corner of the car, release it, then watch if it comes back up and stays there or if it keeps bouncing up and down a few times. One word of warning though. I made a real big deal in my classes about people resting their feet on car bumpers, especially now that they're all painted. I don't ever want to see a mechanic do that to his car because he is likely to do it to mine too. Use your hands on the fender, not your feet on the bumper.

You also have to not get real aggressive. A lot of newer cars are very flimsy and you can actually dent and crush fenders with your hands.
