My sister's car in NH. Any ideas? The Sienna page has treated me well!
" Have an older mint Camry very low miles. Hit a car jack in middle of highway and no one could see any damage, but it clunks back passenger when going over deep sewer covers all over my city, and bumps/deep cracks in the road.
Changed both rear struts today and sway bar links BUT still clunking. So bummed, a lot of money and garage has no other ideas. Thanks. Back seat had to come out to get at the new Quick Struts. Toyota dealer had looked too, course they also did not drive far enough to hit a bumb, so said maybe just a noise nuisance (bull)".

 

Did the clunk start only after the road jack was hit?

 

Yes, new since hitting the jack.

 

Speculate the jack bounced up and hit something under the car. Check the exhaust pipe shields and such for bending. Perhaps something was bent and now is in closer contact with another part then it hits said part when going over a bump.

For struts typically the only thing that might knock is the upper strut mount if worn out.

Sway bar bushings make a rattle when going over a bump.

Have you check the links connecting the sway bar to the swing suspension arm?

One time hit something on the road with a front tire which drove a front strut upper mount all the way up into the hood and damaged it, thus carefully examine the chassis for damage.

As best one can, find out what kind of jack was run over and where was the car positioned when going over it. Find something similar to the jack and start positioning it under the car to estimate where it might have bounced up and hit it.

Those are excellent thoughts and I will check them out.
