Datsun 1200 axle shafts come in two sizes: H145 for all cars, and H165 units for all 1200 Trucks. Both are 23-spline axles, although the truck axles are a larger diameter and so they do not interchange.

Overview
Sectional view of rear axle
Axle Shaft Removal
Remove the individual axles from the axle housing (main body).
- If replacing one side, jack that side up to prevent oil leakage. Otherwise drain the axle housing.
- Unscrew the brake line at the rear of the drum backing plate. Plug the line.
- Remove the brake drum, then remove the four bolts that are at the end of the axle tube. They are accessible via the hole in the axle. These will have nylock nuts on the ends.
- Pull out the axle. This may come out easily or you may have to jiggle the diff where it connects to the tail shaft to loosen the spline. If all else fails the use a slide hammer and connect it to the axle where the wheel lugs are. You can also put the drum on backwards and lightly attach the lugnuts, then use the drum as a slide hammer.
- Remove the seal just inside the axle that sits behind the bearing. Install a new seal upon installation
- Mark the axle on back to indicate which side it came from
chain hammer may be needed to extract the side shaft
Axle Bearing Removal
To replace the bearing, or to replace the brake backing plates from the axle, you will need a cold chisel, an anvil of some description, and a big hammer.
- The bearing retaining collar needs to be removed first
- Use the cold chisel and or an angle grinder to cut the retaining collar off – be careful not to damage the axle shaft, unless you plan to replace the shaft.
- Use a long bearing puller (or chain of pullers) to remove the bearing.
- Alternatively, use a grinder to cut the bearing until it can be knocke d off.
- After the collar and bearing are removed there will also be a thin washer to remove, it should just slide off and then the backing plate will slide off
Keep track of the Shims that go between the bearing and the backing plate. They may differ RH axle vs LH axle
Always replace with a new bearing.
Bearing Retainer
Axle Bearing Installation
Once the old axle bearing has been removed:
- Slide the 1200 thin washer on the axle the same way it came off
- Slide the drum backing plate onto the axle – make sure that it is on the right way (shoe mechanism facing out)
- Press the bearing back on to the axle
- Either get them done professionally (for the cost of a few dollars it will be done right)
- Or get a big pipe/tube of the right diameter of the inner race and bash it on without damaging the wheel lugs or the bearing.
- Press the retaining collar on to the axle (as above)
The bearing is held on a by a collar (a plain ring). This has to cut off with a cold chisel, then a new one pressed on.
Bearing is retained on by shaft collar
When replacing a rear axle bearing, check the wheel bearing-to-housing end face clearance and adjust with shims.
Axle Shaft Installation
- After fitting the bearing as above, fit a new seal into the axle housing end.
- Put the shim in behind the bearing – don’t bend it too much
- Insert the axle into the main body. You will need to line up the spline into the diff centre and gently persuade the axle into place
- Tighten the 4 fastening bolts
- Reassemble the hand brake shoes and mechanisms
- Fill the differential oil
- Replace brake hard line
- Bleed the wheel cylinder
Wheel Seal
Wheel Bearing Packing
Re-pack your rear wheel bearings every two years. They are just ball-bearing (not the stronger roller bearings) so need all the help they can get.
Grease needs to be stuffed into the ball bearing.

every 30 months/30,000 miles: Repack wheel bearing grease

Axle Seal
Datsun 1200 uses the same rear axle/wheel hub seal as Datsun 510. One is required for each side of the car. The same seal is used by H145 (1200 car) and H165 (1200 truck) rear axle assemblies.

NOTE: Measure bearings before buying replacement. Over the past 40 years, the axle housing may have been swapped. Early and Late 1200s use different size bearing.
NOTE 2: The standard 6206 bearing has a bore size of 30mm. The 6206 bearing with a 32mm bore is called a "special bore size" bearing. For example: one NSK bearing 6206 (id is too small for axle) and 32 mm (correct inner diameter).
