Symptoms
A dead speedometer after fitting free-wheeling hubs, or a stripped speedometer pinion.
The fix, step by step
- Early trucks (before about 1966) drove the speedometer from the very front of the transfer case with a crush-sleeve pinion, which only worked because there were no free-wheeling hubs.
- SNLC says Nissan redesigned it around 1966 with a splined pinion behind the 4WD flange in the transfer nose cone, and he upgraded his 1964 to that later design for Warn hubs.
- Pinion tooth counts also changed with tyre size, so match the gear to your tyres.
