rumbling when cutting the steering wheel

awhopper · 02-28-2013, 09:14 PM

I have a 2012 z. I just noticed when I cut the steering wheel all the way to the left or right there there is a strong/loud rumbling. Anyone know the reason?

Thank you.

Cavitation in the power steering pump. Normal. Just don't make a habit of doing it. It will eventually ruin the pump.

is there permanent fix for this?

If it's happening while you are sitting still, it's probably the pump (my guess would be a pressure bypass doing what it's supposed to do, not cavitation, but I'm no expert). If it's happening while you are rolling, it's probably the tires.

If it's the pump, just don't turn the wheel to either extreme. If it's the tires, not much you can do but get quieter tires.

Many ppl, including myself, have quite a bit of tire noise when making very sharp turns at slow speed. It's normal, just annoying.

Cold Temps? My tires feel terrible in the cold weather when turning sharp.

It happens when I am pulling out from a parking spot or drive way. It is definitely not the regular tire noise.

Thanks for the help guys.

A technician told me this is normal. He said it's called camber roll, but he could have just been handing me a line...
