Well I installed 2 new front Hub assemblys in my AUII the other day, and now everytime i do a sharp left there is a loud whining noise. I assume its not the hub assembly because they were brand new, so I figure I must of done something wrong. Didn't tighten things up enough maybe?
Any ideas what could cause it?

You may have not done them tight enough. Some wheels bearings require to be tightened bull s**t tight, loosened, them re tentioned. Not sure on AU, but i'd go with it being a tightness issue.

Yeh, you were right. Tightened them up this morning and the noise is completly gone. The only up side to the whole saga of replacing them myself is i can now do it 10x faster, oh and i saved 150$ .
