Squeaky noise from rear right suspension going over bumps

[benvigier14]

My s4 has 90k miles on it and it has recently began making a squeaking noise since the beginning of winter. The noise gets worse in the cold and if there is anyone sitting in the back seats. What is weird is that it practically disappears when it is warm out or if it is wet or raining. The noise used to only occur after going over a speed bump but now I hear it every time there is a slight bump or unevenness in the road. The noise seems to be coming from the top of the shocks but Im pretty sure It is a bushing because the noise disappears when it gets wet. From what I can tell you can only hear it on the inside of the car. I have sprayed silicone spray on every bushing on the lower side of the suspension to see if it changed anything and the noise stayed the same. I will include a video soon but any help would be much appreciated.

sounds like your rear shock mounts or possibly the rear rubber spring seat. Get a fat friend to bounce on the rear of the car and listen where the sound is coming from.

I literally just had the same issue. It was the bump stop where it goes into the plastic shield around the shock shaft. Sprayed everything on it and it wouldn’t stop. Had to put anti seize in it. Had to use a straight screwdriver and keep working the anti seize into the grommet like connections to the shock mount itself at the top and at the plastic shield. Just take off your when and the bump stop will just pull out of the shock mount with some effort. Smear it in the top and work it into the bottom with the screw driver tip. The grommet at the bottom is really tight so you really have to pry it in there.
