I have a 2005 Camry with original struts, and have about 180k miles on them.
My issue is that I don’t know if I should replace them or not. I inspect them and see no oil leaking. There’s no weird tire wear patterns.
I try the bounce test and think they are fine.
While driving over bumps I feel some bouncing going on but I don’t know how much is acceptable and how much is not. I don’t mind what bouncing I have. The ride quality is fine for me. I highly doubt my opinion has any weight because I would imagine I have gotten use to the ride quality and wouldn’t notice if they are bad or not.
Is there any scientific testing I can do to see if they should be replaced? Like for example, attach a sensor that measures the number of bounces, place a weight of X pounds onto the strut, remove the weight, if bounces reported by the sensor is greater than Y, then strut is bad?
Doing a bounce test by using my body weight and seeing if it bounces “a lot” isn’t really good for me. To me, my car doesn’t bounce “a lot”. Doing the bounce test, it bounces up once past the neutral height position, then goes back into neutral height position, and then there’s some forward to aft movement, then it stops. I think I’m good?
