    I had the front struts replaced. I looked at the strut diagram and replaced most of the parts associated with the front struts. The rear shocks were also replaced. New brakes were installed on the front and rear. The front rotors were replaced. Mileage 124000 miles.

    I thought this would might solve the squeaking when I went over a speed bump in the parking lot. It did not.

    I would appreciate any suggestions to fix the squeaking.


    Thank you in advance.

    it's usually suspension bushings.

    One member recently reported that by lubricating the bushings on the front suspension lower arm subassemblies, he was able to eliminate noise similar to that reported by the OP. So that would be something to try. If the noise goes away then you've identified the problem area, and if the noise returns, then you would have to replace the noisy lower arm for a permanent fix.

    I hope the OP is not talking about a 2013 Prius - that seems way too young to have such a problem.

    My 2007 with 96K miles also squeaked in the front end. In my case it was whenever I made a turn up a curb with the front left suspension loaded, and during moderate heavy braking with front end dive. I isolated the cause to the anti-roll bar bushings. After they were sprayed with silicon and coated with petroleum grease, no more noises.
