differential.
A hollow open-front banjo housing and hollow axle tubes replace the solid central sphere. A separate front carrier, gasket, eight fixing references, pinion flange/seal and two toothless side-gear boundaries connect the existing driveline studies.
Factory plates support these component boundaries. Every new size, station, hole pattern and shell contour is an estimate. Existing rear track, wheel-end datums and the propeller-shaft flange drawing endpoint are retained. No axle ratio, casting version, hypoid offset, spline engagement or installed clearance is established.

Factory evidence and configuration limits
Factory shared rear-axle plate 146 shows the front-removable carrier, housing, 2A7027 gasket, eight carrier studs and two side gears. It distinguishes disc-wheel and wire-wheel cases and lists a case revision from GAN6-182001. This reference does not select a fitted case version from the car’s year alone.
Plate 147 separates pinion bearings, spacer, 88G320 seal, dust cover and ATA7056 universal-joint flange. The separate pinion-support comparison now distinguishes shaft/bearing/spacer/depth-washer/dust/retention roles. An independent cage/crown-wheel/side-support comparison adds the remaining large boundaries, without actual teeth or working gear mesh. Ratios shown on the shared plate are not applied to this car.
Drawing connections
| Boundary | Construction choice and uncertainty |
|---|---|
| Housing / carrier | 165 mm outer and 159 mm inner spherical radii provide a hollow banjo approximation. An open circular front joint has eight estimated holes on a 312 mm PCD. The 0.5 mm gasket and matching faces are drawing choices, not fitted compression, casting contours or drilling dimensions. |
| Axle tubes / half-shafts | Tube outer/inner radii remain 32/22 mm and their ends retain the old wheel-end stations. Tips now extend to ±40 mm after an explicitly unmeasured50 mm inward extension; toothless gear boundaries move to ±40…68 mm for the estimated cage end-wall relationship. Their 11.5 mm bores are geometric boundaries, not splines or measured engagement. |
| Carrier / pinion flange | A hollow taper and four exterior web cues distinguish the carrier from the housing. The pinion flange shares the existing propeller-shaft drawing face and its estimated four-hole 70 mm PCD. The inherited centered pinion axis is unverified; actual hypoid offset and flange alignment are unresolved. |
| Surrounding obstacles | Existing leaf springs, clamps, dampers, straps, tank and exhaust references remain available in the combined view. No suspension travel, tank clearance, carrier sweep or loaded axle registration is verified. |
Workshop use and missing internals
Isolate the housing to inspect the open carrier mouth and through-axle passages. Select the carrier, gasket or pinion flange independently to understand the joints. The two side-gear envelopes mark where the half-shafts end; the cage and smooth crown-wheel/side-bearing/cap boundaries now have a native comparison. Exact pinion/crown-wheel teeth, planet internals and bearing adjustments remain unmodeled.
The exploded view separates reference groups to expose geometry. It does not verify half-shaft withdrawal distance, carrier release, pinion-flange removal, bearing preload, fastener access, support points or a safe replacement path. Fitted identification and the applicable workshop procedure remain necessary before a removal rehearsal can be trusted.
