Ford Ranger / B-Series :: 1999 - Power Steering Shudders?

I had suddenly developed a case of P/S high frequency SHUDDER, on my 99 Ranger, when the steering wheel was moved to either side of center. The fluid level & condition were A ok!!!!, I have kept it changed, so it's never gotten dirty. I removed about 4 oz of fluid from the P/S pump reservoir & added a like ammount of SeaFoam Trans Tune, to bring the level back up to full. In about 10 min 90% of the shudder was gone, After a 40 mile fishing trip to the lake, 99% was gone. The next day, after another 40 mile drive to the lake, fishing, it's ALL gone. So if your experiencing P/S shudder, try a SeaFoam Tans Tune treatment & a fishing trip or two, maybe it'll tune both of you up, did ME!!!! LOL BTW this is the second time the Trans Tune has worked on a P/S sticking/shudder problem, worked on my 94 Taurus two years ago, when I was experiencing a "sticking" problem with the steering wheel turned WELL off center & it's still ok. So if your having that kind of P/S problem, don't be afraid to try the Trans Tune, & a fluid flush & change, if it's dirty, like the Taurus fluid was, it just might WAKE things up.
