I just replaced my PS pump, PS Pulley, and serpentine belt on my 96 GC 5.2 litre. Afterwords it squeked all the time even when in idle. I sprayed some wd-40 on it which appeared to work it does not squeak during idle anymore. However once I get up to around 1500 rpm the squeaking comes back. Any suggestions on hoe to remedy this would be appriciated.
