3503230-W03 Rear Wheel Hub Assembly for CHANGAN CS35 1.6L 17~ L
DUHUI Bearing supplies 3503230-W03, a rear wheel hub assembly for the Changan CS35 1.6L from 2017 onward. It is a third-generation integrated hub with a double-row bearing, five bolt holes and M12 × 1.5 wheel thread, built for the rear right position, while the opposite side of the same axle uses a different number. The table below records the declared configuration; the ordering checks that follow cover the ABS and mounting details that a part number alone cannot fix.

Important: 3503230-W03 is the rear right hub unit. Check the VIN, the number on the removed part, the ABS plug and encoder ring, the five-hole mounting face and the M12 × 1.5 thread before the order is placed, and do not treat an ABS sensor or fasteners as included unless the quotation states them.
DH Code & OE Reference Numbers
DH Code:
OE Numbers:
Changan: 3503230-W03.
Reference Numbers:
RM931070R.
NT-3645 is an additional reference number for this part; match it to the removed part before relying on it.
Vehicle Fitment
3503230-W03 fits the Changan CS35 1.6L from 2017 onward in the rear right position, as the rear wheel hub assembly for that application.
The application is confirmed for the 1.6L CS35 from 2017 onward. On vehicles built near a model-year change, confirm the axle and side from the VIN rather than from the model year alone.
Product Features
- Fixed rear right position – this number is the rear right hub unit; the paired left rear position carries its own number and is not a substitute.
- Integrated third-generation layout – the flange and the double-row bearing are supplied as one assembly, so the wheel-end mounting interface arrives matched as a single unit.
- Five bolt holes with M12 × 1.5 thread – these two values define the wheel-fastening interface and are the quickest dimensional check against the removed part.
- Declared GCr15 chrome steel – a material callout for this aftermarket unit, distinct from an OE material specification.
- ABS equipment is build-specific – an integrated wheel-speed sensor is not confirmed for every build of this model, so sensor presence, plug keying and encoder ring have to match the vehicle.
- Hub unit only – a nut, mounting bolts or a separate sensor are not confirmed as part of the supply, so add them to the order when the repair requires them.
Ordering Verification
- Match the VIN to the Changan CS35 1.6L from 2017 onward and confirm the rear right position for this hub assembly.
- Compare the number on the removed part with 3503230-W03, and rule out 3503230-W04, which is a different rear unit and not a substitute.
- Confirm the ABS configuration on the car: sensor presence, plug keying and encoder ring must match the removed unit.
- Measure the five-hole mounting face, hole pattern, flange height, M12 × 1.5 thread and fitted depth against the old part.
- Do not substitute 3502220-W03, the paired left rear unit, on the basis of similar external shape.
Installation Notes
The rear wheel hub assembly and rear wheel sensor are integrated on ABS-equipped vehicles and must not be disassembled for repair. Tighten the rear hub fastener to 66 N·m, install in the reverse of removal order and adjust the parking brake cable afterwards. Use new locking hardware, never hammer the unit or press through the races, seals or encoder ring, and confirm final torque against the VIN and current service manual; 66 N·m does not apply to wheel nuts.
