Is it time to replace my CV's?
 

I'm still getting to know my 924S so I need a little help analysing the noises it is making. :)

It sounds like I drove over a loose manhole cover every time I switch from brake to throttle. I'm guessing that there is slop in the CV's to make this noise. If so, is this mildly bad (keep driving until I has time and the parts to replace them) or seriously bad (park it until the fix is done)?

Similarly, engine braking at 2200 rpm or less results in loud whining noises. Is this normal or something else that needs to be fixed?

If the noise is easily heard then it's new clutch time. The cv joints rarely make that much noise. You need to have the vehicle inspected to diagnose what requires fixing right now and what can wait.

There shouldn't be any whining noises under engine braking.

Raise the rear of the car and leave it in gear with engine off. Turn a wheel to see the noise comes from. It should be obvious whether it eminates from front or rear.

Clang! Clang!

Accelerate, decelerate.

It's the clutch.

Will not last much longer.

Listen to these guys. I replaced my rear axels and the noise didnt go away. I ended up replacing the clutch and I could have used the $400 I spent on the axels towards the clutch.

$400 could do a quickie clutch complete.

You do the labor.

Besides I paid less than $200 for a set of rebuilt axles. Not recently though.

Its been about a year since I did it. The axels were about $175 each new from Lobro Molly. Porsche wanted like $300 each for the same part. However it would have come in a pretty Porsche box.

Hehehe

My mistake never replace parts without testing or inspecting first. Dont be a Roger!!! A little knowledge and ability can be a dangerous thing.

As Britwrench says throwing parts at these cars is expensive and frustrating. Lesson learned.
