3550070-UQ1 Rear Wheel Hub Assembly for CHANGAN CS35 16- L
DUHUI Bearing supplies 3550070-UQ1 as a rear wheel hub assembly for the CHANGAN CS35. It is an integrated hub bearing unit for the rear left position, not a loose bearing chosen by bore, outer diameter and width, and it serves the disc-in-hat rear brake layout in which disc service braking works with a drum parking surface formed inside the disc hat. The left and right rear units are separate part numbers, so the required side has to be confirmed against the vehicle details.

Important notice: Confirm the complete number 3550070-UQ1, the rear-left position, the CHANGAN CS35 application and the disc-in-hat brake layout before ordering. No inner diameter, outer diameter, total height, flange diameter, PCD, center bore, thread or spline values are declared for this number, so compare the new assembly with the removed unit and check the ABS connector, hub studs and brake-disc mating face.

Vehicle Fitment
3550070-UQ1 fits the CHANGAN CS35 from 2016 onward in the rear left position, in the disc-in-hat rear brake configuration.
The 2016 CS35 export version uses a 1.6L JL478QEE 1598 cc BlueCore DVVT DOHC gasoline engine with front-wheel drive. That engine detail is context for identifying the vehicle; the rear hub application itself is not divided by engine, so a different powertrain version in another market should be checked against the VIN, the removed part and the hub and brake structure.
Some catalogues list separate rear hub numbers for the 2017 and 2018 CS35 versions; confirm the model year and version by VIN before ordering.
Product Features
- Integrated assembly. 3550070-UQ1 is a complete rear-left hub bearing unit with its mounting flange, so it is identified by part number, side and brake layout rather than by bore, outer diameter and width.
- Disc-in-hat rear brake layout. The hub serves a rear brake set that uses a disc for service braking and a drum surface inside the disc hat for parking, and both functions must match on the replacement.
- Side-specific design. The right-rear counterpart is 3550070-UQ2, and the two assemblies are not interchangeable on appearance alone, so the side belongs on every order line.
- Aftermarket reference. G3-479 is a common aftermarket reference used alongside this number. It is not confirmed as an official OE number and should never be the only identifier on a purchase order.
Ordering Verification
- Quote the complete number 3550070-UQ1, including the UQ1 suffix, and do not shorten it to the base digits.
- Confirm CHANGAN CS35 from 2016, rear left, and the disc-in-hat rear brake layout, then verify the model year and version by VIN.
- Do not substitute 3550070-UQ2, the right-rear assembly, and do not assume the left and right units can be swapped.
- Do not interchange with 3500070-UQ1, 3502150-W01, 3502150-W02, 3502220-W03 or 3503230-W04; each is a different CS35 rear configuration.
- Compare the removed unit with the new hub assembly: mounting hole count and spacing, center locating dimensions, hub studs, sensor wire length and routing, plug keying and brake-disc mating surface.
- Supply the full OE number, side, model year, brake type and VIN with the enquiry; G3-479 alone does not identify this wheel hub assembly.
- Treat look-alike spellings such as 3550070U01 and 3550070-U01 with care, because character similarity does not prove that two numbers describe the same assembly.
Installation Notes
Inspect 3550070-UQ1 for drop damage, rust, bent studs, flange distortion or sensor-wire damage, then turn the hub by hand; it should rotate evenly without binding, scraping or noise.
Keep the sealed unit packaged, never wash or re-grease it, and clean the axle face, threads and disc mating surface before fitting.
Use new one-time locking fasteners and the vehicle maker’s procedure; CS35 service data lists 66 N·m for the hub nut and 110 N·m for the wheel nuts, confirmed per VIN.
Procurement And Supply Information
3550070-UQ1 is supplied as one rear-left assembly; custom marking and private-label packaging can be arranged for approved B2B quantities and are confirmed at quotation.
Ask for the current quality-system certificate, product drawing, first-article inspection report and written warranty terms together with the quotation.
Until those documents are approved, treat the part as a sample or low-volume validation item rather than an approved production source.
Quality And Compliance
Production of 3550070-UQ1 follows the dimensional and material tolerances agreed with the buyer, and batch reports are issued against the inspection items and sampling plan written into the purchase contract.
Documents that name another hub number do not cover this assembly, so request certificates and test summaries issued for 3550070-UQ1 itself.
