Had a power steering fluid leak on old pump. old pump had crack in it, so i replaced it with a brand new one. its been 2 days of driving and im still losing fluid; however there are no signs of leaking. could it be air in the lines? i did turn my wheels and all after replacing pump and topped it off after turning the wheels back and forth a few times initially. after running the truck and it makes a grinding noise from low power steering fluid, i go to top it off (again and again) and the remaining fluid in the reservoir has a whitish foamy look to it. any input would be greatly appreciated. thanks!

 

Your rack might be going, thats what happened to me recently, I replaced the ps pump just to find out it was not the problem...

 

I agree, check out the boots on the steering rack. They can hide/leak quite a bit of fluid in there. The white foamy look you have is air in there indicating you still have some kind of leak obviously.

 

If yo are losing fluid then it is leaking somewhere and you should be able to find it. Clean everything off with a spray on degreaser and rinse everything off and then look for leaks.

 

I bet it's filling the boots?
