First of all, it's my opinion that, if after the manufacturer's recommended break-in, you get on it once, running hard through three gears, and now the axle howls, there is a serious freakin' problem with West Coast Corvettes' supplier of rear axle assemblies.
*If* you've been in touch with West Coast Corvettes, they admitted there's a problem but they haven't been back in contact for over a month, in my opinion, it's time to be more proactive.
First thing to do is to write West Corvettes a letter briefly explaining the problem and "demanding" (politely, in the legal sense, not, angrily, in the literal sense) they either refund your money or repair the rear end to your satisfaction. End the letter by giving them a firm deadline and stating that if they don't respond by that date, you'll take legal action to recover your loss.
Send that letter by certified mail with return receipt requested. If they don't respond by your deadline. Go down to the Superior Court nearest to West Coast Corvettes' location, file a small claims case and have the OCSO serve West Coast Corvettes with the papers.
In reading this tread, in my opinion, there might be an inordinate amount of problematic rear axles coming out of West Coast Corvettes. It's certainly possible they have a "supplier problem" and are working to fix it (and I hope that's the case) but the fact that a customer has made them aware of the issue and has not had contact in a month and another is already going to sue is not a good sign.
Buyer beware, people!!
Don't make price *the* prime factor in a purchase of a rear axle assembly.
