I picked up a Durango steering set last weekend for the TJ.
Now, I went whole hog and took the box, pump, and cooler. As it's time to get moving on this, I'm having second thoughts about the pump and cooler. I know the box swaps right over - any reason the pump won't? Before I rip it off?

Just so you know you may have to "massage" the tube in front of the box to fit it,.. What year did you get box wise?

From a 99 V8.

Well, certainly doesn't look like it would fit....oh well. :(

Sorry, my mistake on semantics....it will not BOLT up correctly.
Give me a big enough hammer and I can get a 5.9L CTD in there. :D

It should bolt in,.. It's just a touch longer unless they changed in 99

You talking the box, or the pump? I know the box will fit.

I put one in my 99 XJ.... I took the Durango box out of a TJ. It's tight but it fits.
It will limit your turning radius a bit...

How about a Durango upgrade for your TJ :)

You wouldnt need the pump. The TJ pump is very torqy as is, and nothing would be gained by running a durango one.
The only way you would want a different OEM pump is if your TJ is a 4 banger, and even then, you can esily mod the 4 banger pump to match the output of the 6 cyliner. On the 6 bangers there is usually 1 x 15 thou washer on pressure releif piston, where as on the 4 banger there are two. The flow orifaces are usually the same. Pull one of the washers out of the 4 bangers pistion and you will run the same psi as a 6 banger pump.
Pull out both and you will run about 100-150psi over stock. Drill out the oriface 1/64" and you will flow more from the stock pump. That is commonly referred to as hot rodding a stock pump. Use a good cooler, and good fluid if you hot rod. They neccesarily last to long when they are hot rodded.
Definately run the cooler either way. Its just better for the system.
The stroke on a Durango box is slightly limited compared to TJ box. Three options.
1. Put it in and leave it. If you rub already, not a big deal.
2. Have a rebuilder tear it down, the travel can be extended to that of a TJ box.
3. Use a WJ stock pitman, which is about 1-1.5" longer then a stock TJ one, with pretty much the same drop, and can be had from the dealer for under 50 bucks. They usually have them in the wharehouse right in red deer.

Thanks, that's what I was looking for. If it's not an upgrade, I won't bother. The only reason I grabbed it was because the engine was out and it was easier to just grab everything instead of separating the box.
Thanks for the info on the WJ arm too. I'll grab one of those too.

Just be carefull with the WJ arm if you are running a 35" or more tire. The longer arm will add stress to the box.
Mildly wheeled on 35's should be ok, and wheel the crap out 33's is fine.
Stop at a chev dealer for ac delco ps fluid. Really high quality and ultra cheap.

Well, the TJ is on 35's, and apparently, I like to "catch a lot of air" when wheeling....
Switching to 34 x 9.5 x 15 pizza cutter Narrow SS....might help a bit with the stress.

Its mostly a diameter thing, and most the failures are usually impact related. Like sliding sideways and having the smack into something.
Regardless, on the older TJ and XJ's, sector shaft failures are really rare. The newer boxes on the 03 and ups are weak and really prone to snapping.
You should be fine.

Hey Bill, whats a good, reasonably priced upgrade for the 03's and up? Any JY swaps?

I'm assuming that the same as previous years would work....Durango V8's and ZJ boxes.

I thought the 03's and up had a different bolt pattern or something that makes them non interchangeable with the earlier TJ's.

I stand corrected, they are different. Supposedly you can redrill one hole and get away with it.
