hard steering on KW Help

there are two ways. On some steering boxes there are drain bolts, but no drain bolt on TWR box. I did it the other way.

I used to separate fluid return line and put it to bucket for old fluid, I drained all fluid from PS pump fluid tank, I closed fluid return fitting on reservour with rubber plug and fill it with new fluid. Guy who assist me started engine and I keept filling system with fresh fluid till I see clear fluid from return line (PS pump sucks fresh fluid in and pumps old fluid out to bucket).

But before you do it do PS pump pressure test to be sure pump is good.

 

Check the U-joints on the steering shaft. If they are seezed it will be very hard to steer.

 

I agree probably u joints in steering shaft.

 

or fith wheel if hard to steer when coupled to trailer

 

needs greese

 

Bad PS pump is loud. ZZZZZZZZ sound, sometimes bubles and foam if fluid.

Sometimes steering box is worn internally, sometimes PS pressure limiting valve spring is broken and steering is hard.

Too many things to check.
