power steering problem

[tellyv]

I'm not sure where to post this. My cuda has a small gm style pump I put a dse resevior on and it's always whined really bad ever since, I dumped the atf I ran in it and put some gm stuff in and it only makes noise when you turn the wheels it used to wine all the time, any suggestions? I did put a little lucas in it and it did'nt seem to help. It works fine I just want the noise gone. Just though I'd ask before I buy a new pump. thanks Telly
