Propjockey,

Thanks man.. you will love your jeep in a whole new way. There is nothing better than diesel fumes, turbo whistle and the raw torque and knowing you did it yourself..

I so badly want to get an old 12vavle cummins and put it in a 70's ford 4x4.

I'm really interested in what your mpg turns out to be. The initial numbers sounded great.

I do believe that I can get a few more mpg when I go to larger tires. I am thinking 35 or 37 which will lower the Rpms quite a bit. Which will make freeway driving better. I have read that the Cummins like to hang around 1800 Rpm on the freeway.

As you guys already know I am running a front Dana 30 . If I run the synergy heavy duty ball joints and maybe add a truss so you think it would be reliable with 37s?

for wheeling 37s, you'd be pushing your luck on that 30. Even with upgraded shafts and u joints, does that not make your ring gear one of the weak spots? FWIW, I know for YJ types the HP D44 out of a '77-79 f250 is a common upgrade. Guys who aren't going full width get the tubes cut to waggy width and use those size shafts. Maybe something worth looking into, as far as adding spring buckets etc.
just throwing it out there

Power steering nightmare

Currently had to drive Oscar 37.6 miles through country roads with no power steering.

No idea what happen. It just stopped working directly after running over a decently large bush while wheeling on my buddies land.

No pinched lines or hoses, plenty of fluid. Just stopped working

Any ideas boys? I haven't looked into what a new runs.

Did you maybe break a gear inside the box?

It's a newer box maybe three years old.

I don't know if I broke a gear it's a possibility! ?!?!

Though I am assuming that if a gear was broken I wouldn't be able to steer it. I can steer it, it's just unassisted.

I called Jeff Daniels Jeep and everyone who was familiar with my Jeep was either off or busy. I would expect them to call tomorrow.

sounds like a seal or something broke, either in the box or the pump.

I cant not think of an easy way to test the pressure coming out of the pump, maybe pop off the low pressure hose and see if anything is pumping out?

Youngjeeper..

That's a really good idea, I was trying to think of some stupid way to put a gauge on the high pressure side. But your suggestion seems much easier.

I found a new pump from NAPA for 57 dollars. I am gonna pull the low side tonight and see if it's doing anything.

When the pump stopped my front axle was locked and I was turning. Is there any evidence that locked axles make the life expectancy shorter on power steering pumps

Bad part is the power steering pump is a complete pain in the A S S to remove. The vacuum pump has to come out to, and that's a real treat.

Remember about a week ago when I said if you do this swap be ready to wrench all the time!! Well here we go again.

Now maybe my experience is different because I drive long distance on roads and freeways, pull a 3500 pound trailer every week and drive on un improved roads. But. ..I TOLD YOU SO.

or it could be because I am not a mechanic. .

Well,

I am not really sure what to conclude if fluid pours out, but if nothing is coming out, well, I am still not sure what to conclude then either, just that there is a problem haha

If my memory serve me correct from Back when I worked at the Dodge stealership about 7 years ago os so . I believe the power steering pump Looks about like a Love Joy connection and one side breaks off. Nothing on a Cummins every breaks regular so If you see a problem about 3 time . You most likely won't see that again.
.. Except for the new 24 valve Ditry Fuel trucks. Any truck above 2003. really .
