Volkswagen Spindles 101
Every classic VW spindle by model and year: bearing sizes, seals and drop options, from the PROs at Airkewld.
The complete classic VW spindle guide
Accurate spindle information for classic Volkswagens is shockingly hard to find in one place. Different model, different year, different bearing size, different drop options, different gotchas. The PROs at Airkewld have worked on every variant of these front ends, and this is the cleanest spindle reference we know how to put together: by model, by year and by performance need.
Link pin front ends
These early cars use a two-piece king pin / link pin front end. The spindle (steering knuckle) rotates on a pressed king pin inside a carrier (yoke). The carrier also houses the steering stops and link pin bushings, letting the control arms cycle through their travel.
| Spec | Measurement |
|---|---|
| Inner OD | 24.90 mm |
| Outer OD | 19.80 mm |
| Other components | Steel thrust washer, fiber wafer shim, centering cap |
All aftermarket drop spindles for this front end lower the car 2.5″ (63.5 mm). They differ in how they're built, and that shows up in how the car drives, lasts and stays safe.
Early ball joint front ends
Factory forged. Stock specs:
| Spec | Measurement |
|---|---|
| Inner bearing | 26.90 mm |
| Outer bearing | 17.40 mm |
| Seal | 131405641A |
Drop spindles require bearing, seal and tie rod end updates to 1969+ spec, so don't bolt them in with your existing hardware. Airkewld offers complete plug-and-play kits so you don't chase mismatched parts across three suppliers. After the update:
| Spec | Measurement |
|---|---|
| Inner bearing | 28.90 mm |
| Outer bearing | 17.40 mm |
| Seal | 111405641B |
Available in drum, Ghia disc and Wide 5 disc (Escort-style caliper). Construction options — cast, forged, welded — match the link pin section above.
Late ball joint front ends

| Inner bearing | 28.90 mm |
| Outer bearing | 17.40 mm |
| Seal | 111405641B |
VW Thing / Safari
The Type 181 is its own animal. Thing spindles are:
- Forged from the factory
- Built with a 3.5″ (89 mm) lift baked in
- Only compatible with Type 181 trailing arms, ball joints and eccentrics
Split Window Bus
The Bus front end is the most complex assembly in the classic VW lineup: spindle, king pins, link pins, seals, bearings, stops and races. Airkewld offers a stock spindle rebuild service for owners who want it done right without the parts hunt.
| Year | Shaft | Inner bearing OD | Outer bearing OD |
|---|---|---|---|
| 1955–1963 | Stepped | 29.90 mm | 24.90 mm |
| 1964–1967 | Tapered | 31.65 mm | 18.93 mm |
Squareback, Notchback, Fastback, Razor Ghia
Two stock variants exist: 1963–1968 and 1969–1973, with different bearings and tie rod specs on the later run.
Drop spindles for the Type 3 are rare and effectively discontinued. The only ones ever developed were built by berT3 in Belgium, and there's no current production. If you're chasing a lowered Type 3 stance, plan accordingly.
