I had left front wheel bearing failure on my '91 B13 SE-R this week. It had a humming sound on the highway that got worse when I made right turns. I removed the bearing assy today and replaced it. The inner row of ball bearings were bad. Even though both inner and outer seals were in place and looked OK, there was some moisture [water] in the failed bearing too. This brings up a good point that I never hear anyone talk about. Ever notice that when you buy those $59.99 rebuilt axles that the factory metal splash shields are always missing? The rebuilders hammer them off and throw them away. For $59 you're not getting new ones, so you put them in with those parts missing. Well there
is a price to pay for that. Just give it enough time.....
