For FIOD automatic transmissions. When the bearing at the direct drum to hub interface wears down or fails, it puts unnecessary load on surrounding components and shortens the life of the rebuild. This single bearing, .225 inch thick, is the correct replacement for that specific position in FIOD, AODE, and 4R70W automatic transmission units produced from 1980 onward.
The thickness specification matters here. At .225 inch, this bearing matches stock tolerances for the direct drum to hub location without requiring additional shimming or substitution. A bearing that is even slightly off in thickness at this position can affect end play readings and drum rotation, so using a part dimensioned to spec keeps the rest of the assembly honest.
This is a single-piece listing. It does not include seals, gaskets, bushings, friction discs, steels, bands, or any other rebuild components. If you are working through a full overhaul, cross-reference this bearing against your complete parts list to avoid gaps in your order.
SKU is picked and checked individually before it ships. The part record travels with the package so there is no guessing about what is inside.
Before placing your order, confirm that your unit carries an FIOD, AODE, or 4R70W designation and that it falls within the 1980-and-up production window for these transmissions. If you are unsure of your transmission code, pull the tag from the unit or check a verified application reference before ordering.
- FIOD automatic transmission: this bearing addresses worn or failed direct drum to hub contact in FIOD, AODE, and 4R70W units, restoring proper drum rotation and reducing internal wear at that junction.
- This listing covers the bearing only; it does not include any seals, gaskets, bushings, clutch discs, steels, or rebuild kit components. Verify your full parts list before ordering.
- At .225 inch thickness, this bearing matches the stock specification for the direct drum to hub position, so fitment does not require shimming or substitution on covered units.
- Contents: one direct drum to hub bearing, .225 inch thick, shipped individually. Article weight is 1 lb. Packed and verified against its part record before leaving the warehouse.
- Before ordering, confirm your transmission code matches FIOD, AODE, or 4R70W and that your application falls within the 1980-and-up production range for these units.
