Steering problems for FORD

I have a 1976 F-250, and I am faced with a problem. I don't know what to do with the steering system. It has a D44 front axle, and I know what you all are going to say... but i have a set of 38.5x15x16.5 TSL's on it. My problem is that the big tires are hell on the power steering ram and after the years of (ab)use that i have put it through the ram has begun to leak. I went to the local parts store and they told me about Lucas Oil, this helped to slow the leak but did not stop the problem. I have priced a new ram, it retails for about $200 to $250 bucks. I have seen rams such as an AGR Rock Ram, but $900 bucks is way more than i want to spend. I am afraid that if i buy a stock ram I will have the same problem over time. Can I use a farm implement ram fom the local farm supply store? I have seen this done but dont know how to go about it. if anyone knows anything about it i would be very thankful.

The stock ram on your truck will continue to leak just like it did on the 77 highboy that we had you could change out to a different ram or you could change over to the 78's steering if you want to put that kinda work into redoing the steering system also you can have them replaced or rebuilt for closer to a 100 bucks so I suggest you compare so prices first.  

The stock steering was never designed for that kind of stress. 38's put a awful load on it. If you put a larger cylinder on it you may have flow problems from box to feed it correctly. The ideal setup would be a custom dual stock cylinder setup if that flow controler in box would handle it. Basically is is custom high $$$ or same old same old.  

Superlift's super runner steering is a pretty cool deal for Ford guys.  It straightens out the angles but it may not fit your year truck. They may have better ideas call them.

I don't know whether the using a hydraulic ram off of a piece of farm equipment will work or not.  But your 76's steering will do the same thing as our 77 highboys and that is just keep wearing down under the strain of the tires until it starts to leak again.  So if you factor in the amount of money that you would spent fixing or replacing over time, don't you think that the $900 would be money well spent?
