What kind of noise?
Engine noise? Gear noise? Tire noise? Engine noise is the only reason to go with 3.73 over 4.10, but only while running empty. As soon as you start towing, the transmission will downshift and the noise will be right back. Gear noise is caused by defective parts, and should be replaced under warranty. Tire noise can be remedied with different tires.
Keep in mind that with the 6+ speed transmissions, rear end ratios don't mean the same thing as they used to. As a general rule of thumb, the gear ratio is effectively one ratio numerically higher with a 6+ speed transmission.
3.42 is like towing with a 3.73 and a 4-speed
4.10 is like towing with a 4.30 and a 4-speed
So if you really only need a 3.73 effective ratio, the 3.42 will be fine.
