Q&A
Q1: Is the ZGAQ-02034 cage made of steel or plastic?
A: Depending on the specific application within the Hyundai axle, we provide both high-strength steel cages for high-temperature zones and reinforced resin cages for reduced weight and noise. Both meet OEM performance standards.
Q2: Should I replace the needle rollers when I replace the ZGAQ-02034 cage?
A: Yes. For maximum service life, we recommend replacing the entire bearing assembly (cage and rollers) to ensure even wear and prevent premature failure of the transmission gears.

A: Yes, we can supply the sun gear, planetary gears, needle cages, and shafts as a complete kit to simplify your repair process and save on shipping.
