Very shortly after the 4/20 flush we started to notice the squeak again. Maybe 2-3 days afterward. It was very subtle though. Had to turn the radio off and AC down to hear it. I also noticed the steering was slightly jittery. My wife didn't notice but I did. We let it go for about 1500 miles and it didn't get any worse. It was inconsistent though. Sometimes no squeak and sometimes a little noise.

There were two things that I did differently that time and it's had me wondering if...
1. The fluid was different (I used up the one pictured above and so I bought the "same" stuff but it was only available in a 1 gallon bottle)?
2. I didn't purge the air out? (I just filled and dropped the car because I was in a hurry)

Yesterday, I had the car up on stands so I decided to flush it again and this time do exactly what I did the first time but using the new fluid. That was to drain, fill 1/2 way, then turn the wheel from lock to lock about 10 times (wheels off the ground). I did that and noticed the fluid level dropped where as the 4/20 flush didn't. I also noticed there was jitter and some resistance at the same time when turning the steering wheel about 270-360 degrees. Then after about 5 complete Left/Right turns there was a decrease in resistance and it started to get smooth.

Only driven about 30 miles so far and its back to no squeak and smooth turning (like a new car). Going on a trip next weekend and I'll watch it closely.

btw..
- I'm thinking I had not purged all the air out.
- The fluid looked slightly darker than new
- Ambient temps now are in the low 90s. (The squeak doesn't seem to be air temp dependent)
