Photos would help immensely here. Need to see what axle is under it, the general purpose front end is a "swept back" design by virtue of what it is. If you have the front end of a light industrial, its not adjustable, heavier design and should have larger spindles, there are a few versions of those.
If for some reason you think those front wheels, one or both are "toed" in at the top, and its speculation on my part, but its possible one or both are fatigued, I broke one last year on an earlier version tractor, an 850 with the GP front end, one wheel was doing that, it should have tipped me off, but I did not get it, until it finally broke in the field. Just a possibility, but I distinctly remember seeing the same thing prior to, when on flat pavement.
The center axle pivot pin is not that difficult of a job, its a wear point on these, maybe less with an industrial front end, but still, more so on a tractor with a loader and GP front end. If the center axle is really bent, its beyond me, never saw one with that problem before, bending something like that and then trusting it afterwards, that could be a real problem. I would suggest making repairs correctly, given it has a loader on it, something fails with the loader up, hard to say what it will do, I was lucky I was headed down hill and the bucket was low when my spindle broke. The biggest concern is checking the wear of the bore of the axle where the pivot pin goes through, if excessively worn, it may have to be bored and a bushing installed to bring it back to acceptable dimensions, for the new pin and bushing. The bolster that attaches to the block may need work, I have seen them offered already rebuilt, you can rebuild those so that all new parts can be fitted, I have to do my 850 soon, I know what it entails thats for sure, really need to see what front end is on that tractor to provide any advice though, lot of posts on front ends of these on the ford forum here.
I would suggest a shop manual, ford shop manual, good uses or reprint of same, ebay is a good place to start, along with a parts manual as well.
Power steering, I am familiar with these on that era ford tractor, but don't know a heck of a lot about troubleshooting, obviously your pump needs to be providing adequate pressure, not sure what the deal is on the inside of the power steering box, likely between the two somewhere. I've yet to accomplish repairing mine, do have a factory supplement on power steering for 600-800 tractors, for reference, need to find it again first though LOL !
Hi Everyone, I just bought a used Tractor 1964 ford 4000 industrial 4 cyl w/5 spd w/front loader and gannon box and it runs great and looks as old as it is, But the problems are...looks like the center axle is bent the front wheels are in at the top and the power steering is not working, its a bugger to turn. My Questions are... Can the center axle be bent back and if not how hard is it to replace it? and how do I check and see whats wrong with the power steering? Yes I'm mechanically inclined I just know nothing about this tractor.
