I have a 98 carrera 4 cabriolet and the torque tube is making noise. only found one in germany from porsche. any ideas on a rebuild state side?

 

I do not know of anyone in the states that rebuilds the 993 torque tubes. You can get rebuilt ones as well as new from Porsche. Yes more than likely out of Germany though....

 

As I have a '96 C4, just curious how many miles on your car Johnny?

 

I'm curious as to what a torque tube is.

 

I have actually not seen a bearing go bad in a 993 torque tube yet. I have seen broken drive shafts though on 993TTs. Also seen numerous bad viscous couplers. Yours would be the first torque tube with bad bearings.

The torque tube houses the drive shaft between the transmission and the front differenetial. It is a round metal housing about 4-5' long with several internal bearings that keep the drivshaft in place between the two.

 

this car has 85,211 I can hear the noise the loudest (on the hoist with a stethascope) at the middle of the tube. only had this problem in the past on 928s. can hear the noise at speed coasting the car out of gear. any used ones out there?

 

Do the front wheels turn with the rear wheels when the car is on a lift? The driveshaft might have snapped -- the way mine was on my former 95 C4 cab -- and the ends could be rubbing together. Mine was such a clean break it looked like it was lasered.

 

Thanks VB!
