Re: New Avalanche owner, questions

Replaced the front shocks with new Bilstein 4600s last night, 1 was completely blown and leaking, the other could be easily cycled with my hand but not leaking. The front end out of control shake is gone but there's still some vibration above 65mph. The tires are AMERICUS brand, and the road noise is still there. I can't tell if it's coming from the transfer case, the front diff, or the tires, it's completely dependent on speed, but doesn't seem to change going over different types of road surface, so I don't think it's the tires. Doesn't matter if I put it in neutral at 60 either and isn't dependent on throttle input, so I don't think it's the trans or T case. I'm going to change the front diff fluid tonight to look for shavings, any other ideas? I drive it to work today and now don't think it's wind noise
