Default Cost of a torque tube replacement

I have started to have a whine from the torque tube which increases to a schrill over 3.5K RPM's as of late. No vibration at all...or clattering...So i am assuming it probably is my converter bearings. The torque tube is original with 108K miles so I was thinking about a complete replacement of the torque tube and converter bearings....I was quoted by a reputable repair shop in my area that a torque tube replacement would be close to 12 hours labor. I have searched and have found no threads with actual dollar amounts of a replacement with a rebuilt tube. So....my question is...How much have you guys paid for a complete job? This way I can get an idea as to what to expect. This shop told me they could press bearings so I am assuming they can rebuild my tube itself and replace my converter bearings also....So...again...guys tell me some stories....Thanks...

We did it in about a day in Matt's home garage, and none of us had ever done one before. I would guess 12 man hours is pretty fair. The traditional approach, as described in the WSM, involves dropping the rear suspension, crosmember and transmission. That takes a lot of time. We didn't do it that way, but no shop would try what we did.

As regards the bearings, pressing out and in the TC bearings is a routine machine shop process. Rebuilding the TT is not. You may need bearing carrier parts as well as the bearings, and these are not commonly available. Ask the shop what they are going to do. Most likely they are going to order a rebuilt TT. That's about $500 net from one of our 928 vendors.

How many 928 TTs has the shop in question done before? You don't want them learning on your car, like we did on Matt's! Our price fit with our level of experience - Free!

if your going to remove the TT and the Torque converter bearings, now is a great time to reseal the auto box, and front pump O ring, it takes a bit more time but if its not done now then when it does fail you will be removing the trans again, If your doing this work make sure to grease the bronze bushing inside the front pump where the torque converter plugs into so it wont seize on startup

I paid about $1600.00 which included the cost of a rebuilt torque tube. If you go rebuilt, have the shop inspect it before they install it. I received a bad one from one of the "well known" 928 vendors that I had to pay to have it installed and removed since they didn't notice the problem before it was installed.

If you are going to replace the torque tube, back date to an early torque tube so you don't have to worry about it pulling out of the flex plate.

I probably need to replace my torque tube and TC bearings. Is it best to go to the circlip style and does it involve more or less work.

Charley, we did the early circlip style on Matt's 91 S4. The only additional work is installing the circlips, and we figured out how to do that pretty quickly. With the right circlip tool, add about 10 minutes versus the later tube.

Or you can get our new clamp and take care of the pullout that way. No worries about setting up the proper distances and measurements. Just like how the Porsche workshop manuals are directing one to set it all up currently, only with a much better clamp. This new clamp will also allow one to go back in, un-clamp everything, do maintenance and re-clamp with no worries about the proper distance being set again. Just follow the Porsche manuals.

$380.00 plus shipping.

Cheers,
Constantine
