    New Pop/cracking sound while sitting in the car in the morning

    I have a strange symptom happening to me and it is only happening at one particular time of the day.

    For the last 3 days in a row, while getting into my car and sitting down, I hear a loud pop. It only happens first thing in the morning, after the 981s has slept overnight in the garage. The garage is roughly in the low 70s (f) right now in the morning. The pop sounds like it is coming from the back suspension or even the parking brake. All other times of the day, I never hear it and i cannot reproduce it. I will try to take a video of it tomorrow morning and post it.

    Car is a 981S Boxster with roughly 60k on it. There is no drievability issues nor any error codes or faults displaying.

    Anyone else have this issue?

    Thanks,
    Ryan

    I’ve never heard of this issue. Hopefully you can catch it on video so we can all have a listen.

    Do you use the parking brake ?

    Yes, it is a manual transmission, so I definitely do use the parking brake. I was ready to record the sound this morning, and it did not duplicate. I will continue to try until the sound resurfaces.

    I do have aftermarket exhaust on it, so it might be the clamps for the hangers. Just another thing to check this weekend.

    Do you really need the e parking brake in your garage? Just leave your car in 1 st gear. I have had problems with the parking brake in the past. Mine uses brake shoes, which sometimes stick to the drum when left wet, like after a car wash, or worse, on the track after a heated use of disc brakes. The drum, which is the inner part of the rear rotors will get heat soaked causing the parking brake shoes to wield to the hot drum. When started in either reverse or 1 st gear, there are small retainer spings holding the brake shoes in place that actually can be pulled out of their sockets trying to unfreeze the shoes from the drum. This maybe unrelated to the pop you hear, as it can be easy to test. Just do not use the e brake for a week and see if your pop goes away.

    The other possibility is your suspension's the outer ball joint seal, or thrust puck seal on your LCA's may have been contaminated with road grit causing wear. If you pinpoint that, a temporary fix is silicon spray through a small tube into the suspected area. Sooner or later, you will need a permeant fix.

    That's a good tip about the parking brake; I always use it since I have a MT but after washing the car the brakes always stick when I back car out of garage after letting it sit for a while. I hate the loud mechanical pop when they release as I always think something is going to break! No more using the e-brake for me after I wash the car. All other times and places, I will continue to use it.

    Thank you for the info. I will get under the car and do some inspecting this weekend on the suspension components and also test the e-brake theory.
