Power Steering Pump Bearing?

[Mike621]

Looking through the how to documents as my power steering pump is showing symptoms of a noisy bearing.

Part 31263GA840 is discontinued, and I am trying to find information on a suitable aftermarket replacement.

Thanks in advance.

Took my core PS pump apart tonight.

OD 35mm, ID 15mm, 11mm width are the specs. Ordered some timken bearings that match the spec of the NTN that was in place.

According to my notes when I took it apart, the original bearings were 6202LH made by NSK. You should be able to use compatible products such as NSK's 6202VV or NTN's 6202LLB.

As you know, size are d=15, D=35, B=11

If available, I recommend to you also replace the front and rear oil seals.

According to my memo, it seems to have been overhauled in October 2020.
