Suspension noise

[bpwestmoreland]

need some help here, my driver rear suspension makes a loud popping noise when I go over a decent bump. I recently did the shocks in the rear, have been told maybe a broken sway bar link, they looked fine, I was thinking a bushing of some kind. Any ideas?
I took measurements of ride heights, they are as follows
DRIVER FRONT 26 1/16
PASSENGER FRONT 26 3/8
DRIVER REAR 25 1/8
PASSENGER REAR 25 1/8
All tires are at specified pressure and 2 brand new in rear and 2 relatively new in the front

Check your rear shock mounts. Make sure the bushings aren't worn out.

I just replaced everything new, mounts, reinforcing plates, the only thing is I have 1 washer that is different on that side. Do you think something as small as a washer could do all that noise?

[Lord Vader]

It's possible. Sometimes the littlest things cause the biggest headaches. I think as long as the thickness is the same it shouldn't be an issue.

I did not check thickness....

Are all your bushings original? If yes, you should think about replacing them. The car will drive like It did when new.

I believe they are probably original, bought the car used a year ago,
