Power Steering Hoses

July 18, 2018, 11:14:54 AM

Hello, All.

I just recently upgraded my steering rack to a unit from a 96 mustang, with maximum motorsports steering shaft. The power steering pump and lines are for a 88 thunderbird sport. After installation of the power steering hoses at the rack, there is a fair amount of movement of the lines where they attach to the rack. Is this normal or should the be tight? New o-rings and teflon washers on new hoses. I have the fitting snugged pretty tight and I am afraid to go any tighter, do not want to strip the threads.

Also, should there be a teflon washer on the fitting that attaches to the power steering pump? My new hose did not have one at that location.

Thanks!!!

Owen

So the two metal tubes that have the nuts on them that attached to the rack and pinion will have some play in them. By play I mean you can rotate them and they will have a little up and down to them as well. Easy way to make sure you don't have leaks prior to firing the motor up is to rotate the pump pulley by hand and circulate some fluid.

I would caution you prior to doing this that you have flushed the pump before you move fluid into a new rack. Once you have flushed the pump then hook up the high side line from the pump to the rack, cap the nipple on the pump reservoir, and put the return line from the rack into a can of some sort. Fill the pump reservoir up and rotate the pump pulley by hand and flush the rack. Once the rack is full and some fluid has flushed through it take a look at it and make sure there are not aluminum shavings. If not then rotate the steering wheel to full lock left or right and then continue to flush the rack. When you get clear fluid and hopefully no metal shavings then go full lock the opposite way and repeat the flush. What you are trying to do is make sure you don't have metal shavings in the pump from the old rack and then push them into the "new" rack and that the "new" rack does not have metal shavings and then push those into what I would assume to be an existing good pump and trash it.

Awsome, new pump installed as well. I do intend to prime the system as you described, just making sure that I have everything installed correctly. I assume the o ring does the sealing at the connection, as well the teflon washers.

Thanks!!!

Google a picture of a Fox Mustang power steering hose and you will see that both ends of the high pressure hose have Teflon seals.

Sweet!! I have a spare one that came with the new pump, I will put it on the new hose that is missing. Cannot wait to get the sport back on the road, been setting much too long.

Thanks!!!

Be careful how much you tighten then. They can be damaged pretty easily

a decent mod is to cut away the metal that is in the way of all that gobbled up set of lines.

yes they will be loose even when tight.
