Topic: Durango Steering Box issue, need some help and ideas PLEASE!

[neale_rs]

I called PSC and apparently TJ/YJ/Xj/2.5l/4.0l fittings are all the same. I ordered a 4cyl high pressure and low pressure hose. I'll see tomorrow.

It seems that what is happening is one of these two alternatives:

1) The box in the TJ is not a stock TJ box, and neither is the high pressure line
2) The parts store gave you the wrong steering box, one that does not work with the stock TJ fitting

Power steering pumps are generally positive displacement vane pumps so a smaller line will increase the pressure drop through the line not the flow.... i wouldn't worry about line size as long as its not smaller than the original line for the pump.

only if it cannot sustain flow, there's a limit in pipe (or fitting) diameter difference at which pressure drop is negligible, it is more significant in gasses which are compressible, not so much in liquids, also depends where your pressure hold point is, and in this case is the box when it is loaded (when you turn the wheel, at which point the pressure is applied in between the pump and the box thru the hi-press line and fittings along the way).

There were no fitting issues at all when I put the '98 box in my '01. As for the sensor, I honestly don't recall having to deal with one. So, I guess I'm not much help to you.

I'll have to wait until I swap in the new 4cyl lines I'm getting from Napa. The Durango lines can't be used because they won't allow for the sensor to be attached. From my understanding, the sensor is there to kick up the RPM when turning the wheel to prevent from stalling out.

that's what is for, mine broke and it bogs down in rpm when i reach the end of the travel on my steering, it's good to have (i got one from the wreckers but didn't get a chance to put it on, you have to glue it though if it doesn't come with the connector on it so i'd be interested how yours comes to know if i should just order one).

Is there a chance it doesn't come with the sensor connection? I know I'd be using my sensor, but why wouldn't it come with the connector if I ordered the OEM replacement?

So how did all this get resolved?

I ordered the 4cyl lines and used those. They were a pain to get right, had to position them just right in order for them to connect correctly. I had to use the original fitting from the line from the reservoir to the box as for some reason the guy at NAPA couldn't figure out how to order a new one for me. I think it will work out ok. I'll find out when the build is finished and I fire her up.
