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.

POST 1 / ORIGINAL POSTEROriginal post

Since everyone says the 996 coupe's chassis is real stiff, then I must have a problem. When I pull up into my driveway I go from flat street to a steep incline (always a right turn), I hear a nasty creak and groan from the right side, indicating some chassis flex. Also, when I jack the car up from the left rear mount, I have to pump it up pretty high for the left front wheel to get off the ground. Do I have a soft chassis? Is there anything I can do to tighten it up without buying extra braces, etc?

POST 2Original post

I'm going to say that what you are seeing and hearing is fairly normal. The situation you describe puts a good torsional load on the chassis and it will definitely flex a little in that scenario. Mine creaks a bit too in that situation, although it's mostly the windshield I hear squeaking in it's mount.

POST 4Original post

I get the same thing when I exit the driveway at my office complex. The is the only place I hear a "pop" sound, almost like an acorn falling onto the roof of my car.

POST 5Original post

Have you tried Viagra? I hear the same sound(s) when I egress/ingress my steep driveway.

POST 6 / ORIGINAL POSTEROriginal post

Got it, so I'm cool then. Thanks guys!

POST 7Original post

The 996 chassis is stiff compared to most street cars, the 996 Mk II and 997's are even stiffer. That being said, I was amazed to what how much the car flexed between the A pillar and the clubsport cage I had. Now, I have a Cup cage which is connected to the A and B and stiffened up the chassis much more.

POST 8Original post

Hmmm, I don't have to lift the 996 very far on the front or rear jack point to get both wheels off the ground

POST 9Original post

When I jack the car up from the one of the rear jack points, I can get three wheels off the ground.
