not really, my front bearing was the worst, and it got better on the way back to the trans, so it was kind of progresive i think. did you check the crank? run a razor across it, side to side, as not to scratch it, but to see if there are any noticable grooves. if there are mild sratches on the crank, some 400 grit sand paper or finer can smooth them out, just make sure you sand it in the direction of the scratches, and not to go side to side, this can make the situation worse. this only works if the scratches on the crank are MINOR! just to smooth them out.
