dodge durango steering box upgrade

i cracked my steering box last weekend at logandale and it moves around horribly now. i plan on plating the frame and getting a durango steering box along with hydro assist. they say that it is a heavier duty box and it has 4 mounting holes vice the 3 of a stock grand. but does it have the same spline count pitman arm??

edit: also, if i buy a remaned one from autozone or whatever, will they take my grand one as a core or will they try and give me a hassle??

I was literally JUST going to ask this exact same question! (great minds, you know.)

That is kinda weird actually.....

BUT (more Q's):
I heard that the Durango box (at least that of a 99 V8) has just 3 holes. Correct?

I do not have hydro assist in my stock POS. Is it possible to install?

Is the swap more difficult in any way than just trading it out for a new (ZJ) Steering Gear?

After research on many sites, I have repeatedly found that a '99 V8 Dodge Durango steering gear box will directly swap in. There should be no spline difference issues.

Also, a 1980+ Wagoneer will fit, and is a beefier box, but there seems to be dissent about the usefulness of this: it is time that wears down the gear boxes, so getting an older gear box may not improve any play experienced previously.

I still am unsure about hydro-assist. (did you mean that you already have it and you want to get a steering gear which is compatible?)

Knowing the typical 'diligence' of my local Autozone/Checker folks, I would be willing to be that you could throw an alternator in the box and they wouldn't know the difference, much less a steering gear ever so slightly different from what they are expecting. On the other hand, it would probably mess up their re-manufacturer's assembly line.

Bottom line: I am doing it. Pulling the gear box this Friday. I will let you guys know how it works out. Wish me luck!

To those who have done this mod:

Was it easy?
Do you have 3 or 4 mounting holes?
Would you recommend hitting up the junkyard or Autozone/Checker/NAPA?

Thanks a bunch guys!

car-part.com has a bunch and they are as low as 35 bux, but you never know the shape of those. i think im going to go the autozone route...

as for the hydro assist, i know a stock box with work but ive heard that a durango gear is better and it alone will have any easier time turning my 37s. so im going to drill and tap it for hydro assist. ill make a write-up if in anyone is interested. i will also be plating my frame with to ensure no cracking/bending/breaking there.

I wouldnt put a used box in my jeep, but if you're on a budget and dont mind possibly doing it a couple times until you get a decent box, then the JY route may be for you.

where exactly do you drill and tap for hydro assist?

Here is a writeup on how to do a full hydro steering.
Full hydro and hydro assist are very similar except that with full hydro you just basically remove the gear box, steering column and they give you a strong pump.

i dont know what years have the 4 mounting holes but this is the main reason for the upgrade since the weakness to our set up is the 3 hole design.

Junk yard is probably going to be your best bet.

done on an XJ but its the same. Cheap Hydro Assist - Virtual Jeep Club

when you tap the box you gotta be sure you get all the shavings out.

I had to replace my steering box earlier this year, and I didn't know about this option back then. Autozone does have good deals on rebuilt units with a warranty on them. They honor it, too. They're good quality rebuilds. I bought the KOR steering brace to reinforce it afterward, but I think the Durango box would negate needing this. It sounds like a superior option if you can manage.

Only if the rails are reinforced to help keep the box from flexing. The rails are the weak point. If you plan on running bigger tires along with moderate wheeling, it would be a good idea to do both.
