Q1: Do I need both Retainer [A] and Retainer [B] ?

A: Yes – for a complete differential repair. The pinion pilot bearing assembly requires both retainers. If one has failed or is worn, the other has likely experienced similar stress. We recommend replacing both retainers simultaneously.

Q2: What are the symptoms of worn differential bearing retainers?

A: Common symptoms include whining or howling noise from rear differential, clunking when shifting, metal debris in differential oil, vibration during driving, and oil leaks from the pinion seal.

Q3: Will this fit my ISUZU NPR with the 4HK1 engine?

A: Yes. These bearing retainers (OEM 8970471490 / 8970471500) are specifically designed for ISUZU 700P, ELF, FRR, NMR, NPR, NQR, and NLS trucks.

Q4: What is the difference between OEM numbers 8970471490 and 2402270-P301?

A: These are different number formats for the same Retainer [A]:

8970471490 – ISUZU global parts catalog format

2402270-P301 – ISUZU parts catalog format (alternative)

Both refer to the same bearing retainer [A].

Q5: Can I replace just one retainer?

A: While technically possible, we strongly recommend replacing both retainers [A] and [B] at the same time. If one retainer has worn or failed, the other has experienced similar stress. Replacing both ensures balanced performance and saves labor costs.

Q6: Do you offer wholesale pricing for bulk orders (fleet / shop quantities)?

A: Yes. Please contact us with your quantity and preferred quality level for a competitive quote. Bulk discounts available for fleets, repair shops, and parts distributors.

Q7: What is your warranty policy?

A: This product comes with a 1-year warranty against manufacturing defects. Please contact our support team for any issues.

Q8: Can I get custom branding or packaging?

A: Yes. Custom packing with your logo or specifications is available for bulk orders.
