check the exhausts by trying to shake them very hard, do they produce the same sound?

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

8 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

new to porsche. 2002 996...why do i hear a thump when upon stopping? only a single thump. if i brake moderately heavy coming to a stop light. everything is normal until the weight shifts back upon stopping i hear a mild thump. anyone?

POST 2Original post

can u locate where the stomp is coming from? back, rear? try to shake the car yourself in all directions to see if it appears. if it does let a child follow the sound as you do it.. (guess i got hooked up to child labour here in nigeria!) you ought to open the front bonnet and check for your spare tyre that's it's right in position. check your suspension, each side, by putting your weight on the fenders and releasing.. does sound occur? also you can go under the car, check that all the plastic covers are very tight in position. check the exhausts by trying to shake them very hard, do they produce the same sound? waz

POST 3Original post

Have you tried to see whether the sound occurs when you are on gear or just on neutral? Is your car tip or manual.. a thump can occur also from the tranny while your are stopping and the engine changes from compression to traction as your speed reduces to zero (around the 1,000rpm).. Waz

POST 4 / ORIGINAL POSTEROriginal post

manual trans...i have tried to locate sound by coasting in neutral to about 20mph, then braking moderately hard. sound as if the wing (or something simliar) rises and falls upon completion of a stop. or that the rear suspension thumps as weight trasnfers back onto it at a stop.

POST 6Original post

Usually such sounds are more bushing related.. Just go thru the checklist of moveable parts and bushing-fixed parts in the car.. you have to give us more details roberts.. Waz

POST 7Original post

Take the tire pressure guage out o fthe door pocket.

POST 8 / ORIGINAL POSTEROriginal post

waz996, now that was funny. but i keep the guage in the glove box. since the car is 6 mos old i'll let a dealer start checking things...thought there might be a more obvious source of the sound.
