Steering wheel gets a moan/groan in it when turning to right only and really moans at about 1/2 turn from the stop. All lube points have been hit. Noise sounds like a dry bushing somewhere. Looks as if the lower column is a brg? Anyone know whats up near the steering wheel above the pivot joint?
Words of caution if the the reservoir is still being made like my class A 1995 Ford 36' motor home. My P/S is the same as what was used on Freightliner, Ford, International (Navistar)Buses and Trucks.
Any crud that falls into the reservoir when you remove the large cover or when you remove the dipstick cap, it goes directly thru the entire steering pump system before it comes back up to the filter. ( Bad Deal ) The 4" O.D. filter has a large 8 PSID by-pass valve. A dirty filter should not restrict oil.
A whine-type noise could be aerated fluid requiring a purge of the P/S system. Dwight
We just had one and the lower column bearing was the culprit. The dust shield had come down exposing the bearing and the bearing was rough. Ours was a tilt column and the assembly is put together such that you can't take it apart and IH doesn't sell anything seperate. We had to buy a column assembly and put it in. There is a clock spring up in the top of the column also, but ours was fine. Ours made noice in both directions though.
