'GAS41T', we may as well air the problems here. Please make a list of "so many problems". You'll be helping me. I need to know. Currently, we are at noisy/binding spur gear.
Nick, those rear brass bearings are precision drilled at 2.42mm dia ( + or - 0.01 tolerance). The rear axle is precision ground to a dia of 2.38mm ( + or - 0.01 tolerance). Therefore, in theory, the maximum 'slop' you would get should be no more 0.06mm. It would be awful difficult to say that was sloppy. Having said that, you might have a freak axle. I have to say that, in 7 years, I have never heard of this problem before.
Did this Camaro come straight out of a factory sealed box or had it been around the block (meaning meddled with by another club member before you got your hands on it)? I can only think you have non-Pioneer parts in that Camaro rear axle.
Just in case you were not aware - we offer a pretty good 'sort it out' warranty service. If you are ever unhappy with any element of a Pioneer model, I will get it fixed.
