Power steering situation

[laserjock]

So, took the truck through the neighborhood. Couple observations.

1. Steering is considerably heavy to the left compared to the right. Right feels normal.

2. Hydroboost felt really tight at first and went toward more erratic.


Thoughts?? Air maybe? Steering box is a brand new red head.


Thanks

Is it always heavy or is it only occasional? The only time I've ever seen that happen was a badly clogged spooler not letting fluid through on one side of the box.

Seems to always be heavy to the left. I'm not sure if it's getting worse or if I've just not noticed. I've put less than a mile on it so far.

throughly burp the system before getting panicked.

A few years back, I put a new pressure line on a guy's 1995 Dodge 3/4 ton for him. He said it took two weeks of driving for all the air to work out of the system. You most likely need to go A LOT farther than a mile.

Less that a mile make sure it's totally bled of air which can take a bit with a new box.

I'll not panic yet. I topped the fluid off. It wasn't really low. I'll give it some time. Brakes firmed back up. I suppose it might still be working the air out.

Thanks for the input.

Turn the wheel lock to lock, many times. This will purge the air out.

aeration of the oil is his worst enemy. i've seen systems take a evening of good solid driving to calm dowm.

Jack up the front and lock to lock 20 times with engine off.

That's what I was wondering what's the right way to purge these things? How about cars?

 

[laserjock]

I took it out the the parking lot and did some circles in both directions at full lock. Seems like I have very slightly less turning radius to the left. I mean very slightly. That seems like it could be normal. The thing needs aligned too. Hell I haven't even put a tape measure on it. Need to rotate the tires and do that. Fronts are worn from the old ttb front.

As already posted. Sounds like trapped air in the system. Try doing as already posted to rid the air. Going lock to lock has always done it for me.

Lift front end off ground both wheels...place securly on jack stands.

Fire up truck and slowyly turn lock to lock no weight on front end...keep that going for bout 10 min and press barke pedal on off too.

Its been my easy way to remove air......after vacuum priming the steering box first that is.
