squeeking power steering

I recently blew the metal hydraulic return line that runs under the engine block mount. After replacing that line with hydraulic line (from the pipe at the rack straight to the cooler behind the bumber), I have a squeek that I can't get rid of. I hear a squeek for a couple miles, then it goes away. I'm wondering if there's still some air trapped in the system and was thinking of doing the bleed process again. If that's not it then I don't know what to try next. There are no leaks, and the steering feels normal. Any ideas? I wonder if using the non-factory hydraulic return line could be causing this, but I can't imagine why the low-pressure return line would impact the system, unless it's trapping air somehow.

Thanks for your advice.

 

P.S. - the sound is a "chirping" sound, not the squeal of a lose belt. The accessory belt is the same and did not squeek before. (and remember the chirpign stops after a couple miles). This all started when I had to open they system to replace the low-pressure line.

 

That could happen if your fluid got too low when it blew. Mine got too low from a return line leak and experienced the same issue.

it’s not the repair. Mine is just the hardline cut at the rack and a hydraulic hose running to the reservoir.

it should minimize over time. I’d definitely try burping it by lifting the front end and manually turning the steering wheel lock to lock a few times with the reservoir lid off.

 

Thanks. I bleed with the engine running, and pulled a vacuum on the system to facilitate bleeding, but I did not try bleeding manually. I'll give it a try.

 

Stupid question, but front wheels were raised during the process, yes?

 

My jackstands aren't tall enough to keep the front weeks fully off the ground, but I had the truck raised as much as I could. Most of the weight was off the tires.
