Cisco etherchannel question

I have etherchannel setup between cisco 7500 router and 5500 switch.

For data going from 7500 router everything seems to be ok and data is
well split between four interfaces with about 1/4th sent to each one
(about 40% utilization each right now). 

But for data going from 5500 switch the split appears to be that one
interface has 100% utilization while another one is 20% and others are
less then 10%. So its not really splitting data on random basis to
each interface and uses other interfaces as overflow after the main
one. I don't like this as the one interface that is 100% full appears
to sometimes be dropping packets on either switch or cisco router side.

I'm wondering what I can do to force 5500 to use etherchannel in similar
way cisco 7500 does?
