TRANS-05, Torque Tube Removal, Rebuilding, and Installation
The procedure and pictures that follow show the suspension being lowered after the transaxle has already been removed. It has been suggested that lowering the suspension first may make the transaxle removal easier. However, you'll likely find dropping the suspension first will not give you enough room to crawl up under the car to remove the transaxle.
It may be necessary to remove the starter and slave cylinder in order to access all the bolts / fasteners for the torque tube and torque tube carrier.
After removing these, their construction is evident - they are standard sealed ball bearings FAG 6006 2Z that are pressed into stamped steel carriers with rubber splines molded onto the O.D. There are also little rubber-covered inner sleeves that are pressed into the I.D. of the sealed bearings, that are staked in 4 places. You need to "unstake" the sleeves and remove them, then press the bearings out of the carriers, and press in new ones. On older 944s, the bearing carriers are two-pieces that are riveted together. You'll need to drill the rivets out and separate the two halves of the carrier to remove the bearing.
If the rubber coated inner sleeves are intact, once you've pressed them out of the bearings, save them for reuse. However, if they are shattered or are in otherwise poor condition, you'll need to have new sleeves fabricated. I went to a machine shop to have them fabricate 4 of the inner sleeves out of Delrin plastic (see drawing below).
I used a hydraulic press to install the new bearings and inner sleeves.
