My 5speed whines in 5th gear very softly, but it does. This was happening even before I did my engine rebuild and even before I tore down the tranny. Actually I could not see any damage (to my knowledge) of the 5th gear. What could this be? BTW is my 87 Civic.
Cheers!!
Mine used to whir nicely too, not real loud but obvious, until I think a combination of low oil and a lot of 55 and 65 mph driving changed something. I don't know what caused my sudden increase in noise for sure, hope it was the bad rear bearing. One fear is that I get this all back together, find it's something else in the drivetrain.
In my case, 1992 Geo Tracker 4wd 5 speed, the 5th gear is (was, until Loctite 660) very loose on the countershaft splines. It's not the gear's splines but the countershaft splines though that are the problem. Reverse area was in good shape in comparison.
The splines where 5th counter gear lives have a kind of a rotational hammer damage, sort of a raised up area in the load direction if looking end on, folded over some. I think this is from years of 5th gear highway driving loading, and unloading with traffic using engine brake, etc, but that's a guess.
Anyway, pondering possible causes of noise, I used a new needle/roller bearing in the smaller 5th on the mainshaft (though it seems less robust then the one that was there) and for the big 5th gear situation, tried the Loctite, in case that hammering back and forth from the slop was the cause of the noise. My counter rear bearing was worn also, and that surely contributed some.
Trail Tough guy, who kindly sold me a circlip I'd lost, told me ok to assemble my big 5th gear without the Loctite, but I felt better with. Again, I am not sure what caused my problem, other than I had a really low oil level (missing a couple rubber plugs and not enough maintenance).
I wouldn't worry about yours unless it gets louder over time, or over a week's time like mine did. Lot of other people have mentioned their Trackers whirring along in places. But when it starts to sound like a banshee at high speed, like a plane in a dive or something, something's bad off. I suppose one option was to add back the oil as I did, and keep driving until something blew. Then I'd have known for sure. If none of this was the problem then I still get to do that I suppose. If it runs after sitting so long.

In other news, the output shaft rear seal included in my trans kit sure seems to place the sealing shaft-ride area too far back compared to the old seal. The new puts the sealing area mighty close to the clrclip. There's about a 1/8" or more difference in the old and new locations. The original seal rode the shaft about 1/4" out from the circlip.
I ordered a cross-ref'ed SKF 9795 to see if will fit closer to where the other was, but dimension wise seems like the one I was sent already. I don't want it exactly where the other was, it's worn in some, but not that far back towards the circlip, either. I guess I can not pound it in so far, but it's only .394 or so deep to begin with, whereas the original NOK is 0.5".
