The short version
- Every 944 wheel bearing up front is serviceable: tapered sets behind the 1012N seal, repacked and adjusted like a classic.
- The 1987 to 1995 transaxle cars, 944, 968 and 928 alike, share the A-17 inner and A-3 outer sets.
- The 1986 928S splits by chassis number mid-year, the rarest kind of fitment line.
- The old 924 splits by stud count, four or five.
The transaxle Porsches never got sealed hubs. Their front bearings come apart, get inspected, greased and preloaded by hand, which suits cars whose owners already do everything else themselves.
The serviceable fronts
A 1987 onward 944 wheel bearing order is the A-17 inner and A-3 outer tapered sets with the 1012N seal, shared across the 944S, 944S2, 968 and late 928s.
The earlier cars run the A-6 and A-2 pairing behind the same seal.

The chassis-number split
A 1986 928S built before chassis 92GS861000 takes a different outer set than one built after. The year cannot answer this; the chassis plate can.
It is the most granular fitment line on this site, and exactly why we tell people to match old parts.
Service is the maintenance culture
Clean, inspect, repack with quality grease, set preload, new seal: the ritual is on the repacking page and the adjustment page. Track-driven cars deserve the ritual yearly; cornering load is what these cars were built to generate, and bearings pay for it.
The make overview, including the mid-engined cars’ different story, is on the Porsche page.
Diagnosing a 944 wheel bearing
- Check the grease first; contamination outnumbers wear on these.
- Adjust play before condemning anything.
- Weave at speed and place any hum.
- On a 1986 928S, read the chassis plate before ordering.
- Ask about track use on any purchase.
The routine is on the checking page.
Common questions
Which 944 wheel bearing sets do I need?
1987 onward: A-17 inner and A-3 outer with seal 1012N. Earlier cars: A-6 and A-2.
Can I service these myself?
Yes, that is the design. Hand tools, patience and good grease.
Do 968 and 928 parts overlap?
The 1987 onward front sets are shared across the transaxle family. Match years.
Do I need a press?
Not up front. The rear transaxle bearings are their own deeper job.
Why does a chassis number matter on the 928S?
Porsche changed the outer bearing mid-1986. The plate under the hood answers what the title cannot.
