# Haas VF-3 Used Price & Common Problems | CNC Ledger

> Haas VF-3: used $12,000 to $99,900. Documented problems: spindle rebuild and spindle bearings. What to inspect before you buy.

**Verdict:** inspect

$12,000–$99,900 observed used. Biggest documented cost risk: Spindle rebuild. Buy only after inspection.

**Observed used price:** $12,000–$99,900

**Documented failure risks:**
- Spindle rebuild: Spindle rebuild (VF3SS, 12,000 RPM): full teardown/reassembly documented, including bearing
- Spindle bearings: Root-cause hypothesis for the failed spindle being rebuilt: technician noted the old bearing
- Spindle bearing lubrication: Explicit warning: skipping bearing lubrication (grease) on this air-oil-mist design "is going
- Bearing preload technique matters: Bearing preload technique matters: the rebuild video documents precise shimming and measurement during the spindle rebuild process.
- Rotary/4th: Rotary/4th-axis accessory failure modes (shared Haas service content, not VF-3-specific):
- Z-axis "105 SERVO ERROR TOO LARGE" on home + violent shaking: On power-up the Z axis can fail to home with "105 Z SERVO ERROR TOO LARGE," with "unbearable shaking" while jogging Z. Respondents point to the servo/encoder attachment: "Check the encoder attachment to the motor. If loose it could be moving around causing the motor to try to catch up." A drive/encoder/servo diagnosis, not a quick fix.
