4100 rear steering

[Paulbrunk]

Hope someone can help....can't exactly drop it off at my local dealer. Have the service manual and have bled the hydraulics to a t a number of times. When driving in either 2 or 4 wheel steering the rear axle won't lock straight in 2 or follow in 4...it just randomly flops side to side making it useless. Still try to keep this great old tractor around for pulling a drag and scraper. The manual eludes to a steering solenoid that maybe regulates hydraulics to the rear steering cylinders ?

If it's like the 4166 or the 4186 there is a long rod under the right side of the tractor that runs the rear steer valve. Check
and make sure the threaded rod coming out of it is not bent. It might just need to be adjusted also. Hope this helps and
good luck!

Will give that a quick glance but believe it's a hydraulic problem not a mechanical linkage. Will post what I find. Thx.
