Syncro rings, bearings, and gaskets — kit discipline for CV rebuilders sourcing from Auto Junction.
What you will gain from this guide
- Order full gasket set with bearings
- Syncro hardness matters on hill-route fleets
- Flush and inspect hard parts before reassembly
Rebuilders know the pain: housing open, syncro ring missing from the morning courier. Kit lists sent the night before beat heroic same-day runs.
Standard kit lines
- Bearing set matched to serial or code sheet
- Syncro rings for gears that grind on downshift
- Seals and gaskets — never reuse crushed metal gaskets
- Input shaft bearing often overlooked until noise returns at 5,000 km
See gearbox maintenance and mount timing. Spicer/ZF driveline links in brand guides if the fault is downstream of the box.
