I damaged one axle seal when removing the axles to replace the diff side CV boots. I was in a hurry (realized the seal was bad on Sunday, had a track day on Thursday) and local dealers didn't have the seals in stock. Ordered the Timken 710142 from Amazon with 2 day shipping and installed it Tuesday.
After some 350 highway miles and 3 track sessions the seal was very slowly weeping some diff fluid. Not enough to run down the diff but enough to wet the area around the axle.
Ordered a couple of OEM seals (same part number for Subaru and Toyota (it's a Toyota part) - 9031143009) from a local dealer and they arrived the next day (had I knew they'll come so quickly I wouldn't have bothered with the Timken). Swapped one in instead of the Timken and so far looks good. I have another track day coming up and I'll report back if the OEM seal performs better.
Although the Timken does fit fine and obviously works okay, it's pretty different than OEM. The OEM has a rubber coating on the outer ring while the Timken is bare metal. The seal is press-fit into the diff housing, and I can see the metal Timken not sealing perfectly to the housing (even if the seal around the axle is good).
Timken on left, damaged OEM seal middle, new OEM seal right.
