You have to use very light throttle, light acceleration when it gets below 2000 rpm in 2nd gear.

I experience it every day, at my lot entrance I take a right sweeping corner uphill from 20-30 in 2nd and slow to 10-5mph with a light easy braking, downshift to 1st, and enter the parking lot quietly. But if I stay in 2nd and going uphill my springs will rattle like crazy.
