Hello guys,

My car started to make cracking noise from the front drivetrain.

We opened the central diff. which is coupled to the front differential.

Some of the lamellas are burnt and the housing of the bearing of the lamellas is broken into 4 pieces.

Porsche is selling the complete front diff which includes the central diff.

Do you have any idea where i can buy these parts seperately?

Thanks in advance

 

Here are some pictures;

 

wouldn't this be a warranty item?

 

Not with an SPI 750 conversion...if there was ever an excuse to turn down a warranty claim, 700+ ft lb of torque is definately a red flag.

 

try guard gears... maybe they have a solution. havent heard of that failing though.

I have picked up all sorts of replacement parts from them, even 997 stuff. Great service, reasonable prices, and excellent knowledge of p-cars, parts, etc.

 

Were you running stock sized wheels/tires? Any thoughts as to why the part failed? Di you do a lot of hard launches?

 

Have you put the car on a dyno?

 

Yes i'm running stock sized tires and wheels.

I'm also launching hard alot, im suprised that no one has experienced this yet since there are lots of drag racers in this forum.

 

I haven't put the car on the dyno.

There isn't an accurate load dyno in my town.

 

Launching hard from standstill is always a recipe for disaster with AWD cars. I broke 2 transmissions till now(not Porsches). The shock of launching from standstill is killing them. Maybe the springless clutch has a part too in this, as it cannot act as a dampener

 

Is this a 6 spd car?

 

No, its tiptronic.

 

WhiteKnight, could you please pm me with your email address? I would like to ask you something. Thanks

 

what tires were you using?
