Cost not yet verifiedA worsening "alarm 237 (spindle following error)," especially in low gear, traces to the spindle encoder. Owner: "It got worse and worse... The old style isn't available anymore so I had to buy the new magnetic type along with an adapter cable." The fix is the magnetic spindle encoder + adapter cable (Haas part 33-10037 for the magnetic cable); the discontinued old-style encoder forces the retrofit.

From the research record
- FAILURES: - Spindle bearing failure is the headline wear item across the VF platform. Shop-tech video evidence (VF-SS, same cartridge family as VF-4 per the tech's own comparison) describes bearings failing at ~1 year, with the tech noting "the bearings are not very good" out of the box on some units: video transcript: https://www.youtube.com/watch?v=GFSrmtU
- REPAIR: - Spindle rebuild vs. replace economics (Haas VF-series line item explicitly given): Rebuild: $4,800–$7,200. Replacement: $16,000–$24,000 before install labor. Parts/labor split roughly 40/60 industry-wide. Lead time: 3–6 weeks (rebuild) vs 8–16 weeks (replacement). Rebuild favored when runout stays under 0.0002 in and rebuild cost is under ~20% of
