scored me a 99 grand cherokee steering box tonight on the way home . i had a freind scope out the jeep today and let me know if it was still on it . he told me it was the easiest score ever id better hurry . so i stoped on the way home to me local pull your own . and he wasnt kidding . this thing had the front end striped off . nothing was left . motor trans header panel hood bumper suport front axle and steering column , all gone . all i had to do was take out the 4 bolts holding it to the frame rail and it was mine . luckily it still had the mid steering shaft still on it .15 min. i was out of there. now i need to gather up the rest of my stuff and time to put it on .
well i my self do not know . mark t.on here told us about it . on fleabay theres a place selling a kit which incudes the box and an adapter plate to do this swap . so i figured id try it my self . it looks like it would . im going to try it on my 55
The one on Ebay says its for '52-'59, So I don't see why it wouldn't work on your '53, Another guy on Ebay is selling a kit to use it on '49-'51 Mercs. They don't say that they are Jeep power steering boxs but its not hard to see that they are. The Corvette guys are also using them to get a modern power steering box. '99-'04 Jeep Grand Cherokee is what it is.
dolsen37 here on the HAMB put one on his '50 but I dont think he has driven it yet. He said it was pretty easy to install.
I tried to find the one on ebay, but no luck. Theres a s****yard near me that's really CHEAP. I could probably get one for $10-15. Might be worth a try.
i give 35 for mine at pull a part knoxville tn. with the steering shaft to the column. so i can make a shaft or something with it . im gona make me a thin aluminum plate for now of the jeep box . then i can put it against the bolt pattern of the original box . and see shat i need to do . if need be then i can take it to a local fab shop and get them to make it out of 1/2 inch steel plate and thread the proper holes and taper the other . i dont have the stuff to do that part . or i can see if like the old chevys and a swap they do on those . 3 holes line up and they weld a pipe on top the frame for the forth bolt .
I don't see it mentioned so I ask... what are you using for a pump/reservoir? The E-Bay ad doesn't mention one either.
I think the adapter plate on the Ebay kit is 1/4 thick. You could use just about any power steering pump or the original Jeep Grand Cheerokee pump, if you have done a motor swap you can use the one from that engine. I'm swapping in a 351C into my '55 so I bought a power steering pump and brackets for that engine. Years ago my buddy swapped a small bock Chevy into a Ford pickup, he kept the Ford power steering box and made new lines to hook it up to Chevy power steering pump that was on the Chevy engine.
Be aware that Ford power steering and GM power steering use two different pump pressure rates. Speedway Motors sells modified pumps to overcome this problem, and also lists a power steering pump pressure regulator. Too much pressure will make the power steering overly sensitive and "twitchy".
im aware of diffrent pressures . and i will have to work with that . i going to try to find and original jeep pump. it was gone on this one . when i said this thing was nothing left i meant it . i done some quick measuring yesterday when i was replumbing my brake line . another story . and its realy close to the original 4 bolt gear . humm. the best i can tell by the picture on ebay is the adapter plate moves the box up the frame about an inch . to me the plate looks to be about a 1/2" thick. the first big thing i done to this car was to do a disk brake convertion . i made all new lines and had them all pretty . well i mounted the frame braket in front of the wheel instead of behind because of the way my hose's come out of my calipers . well after doing my spring swap i come to realize that was not a good idea do to now the sway bar could touch the hose's . so i get to relocate the frame brakets behinde the wheels . i think i figures out a good plan on it though this time .
well , most pumps are actualy controled by a valve where the pressure hose gose on the pump. alot of vehicles now use the same style pump . which is actualy shown to be not a good as the old style pumps . the imput shaft likes to shear on them . the valve is easily changed . which is another thing not yet brought out . on the newer vehicles like the jeep . the valve is electicly controled by the computer . { WHAT } . yes . but you can put a non electric one in it . that is how the change the feel in the wheel .
Today 10:47 AM Mark T Does anyone know if the Jeep(Dodge/Chrysler) and Ford pump pressures are different? It would appear that Jeeps use a Saginaw-style pump, same as GM products. Saginaw flow rate is generally considered to be 3 gpm where Ford pumps are generally considered to be 2 gpm. Since Jeeps also use a Saginaw power steering box, it's likely that its optimum flow rate for the Jeep steering box would be the same as that of a GM p***enger car, 3 gpm. Saginaw pump flow rates may be changed by a simple valve change, so it's not a sure thing that Jeep applications (with street tires) would have the same flow rate as GM p***enger cars, but I think that would be a pretty safe bet. Jeeps with big, off-road tires from the factory might be valved to flow a slightly higher rate. (If in doubt, a Jeep service manual of the appropriate year would give you this spec.) So, Mark T, I'd say the answer to your question is "yes, they are different". Note: Speedway Motors sells an adjustable power steering pump flow rate valve to fine-tune (reduce) a pump's output to suit the needs of the steering box. Hope this helps.
So the Fords 2 gpm won't be enough to turn the Jeep steering box? Can the ford pump be modified? I would really like to run the stock pump that came on my on my Ford motor. Power steering systems are Greek to me!
That's right. I doubt if the Ford p***enger car pump flow capacity can be upped, but I'm not an expert on power steering either. I understand that Thunderbirds with power rack and pinion steering used a 3 gpm pump, so this may be something you'll want to look into, depending upon which motor you have and if the bracketry is available to mount the T-bird pump to it. Another place to look is on 4WD and off-road Ford trucks, both OEM and aftermarket. Big tires require more power steering power, and the way to get it would be with a pump with elevated pump flow capacity. Food for thought. Google is your friend.
if at all possible..i'd like to see progress pics. i think my winter project will be installing power steering in my 55 fairlane.
it will be a little while before i get on this . i need to round up more parts and figure out what i want to do about the column or another one . i snag up what i can when i can then when i get enough parts rounded up i try to get time to do it . this gear box was the only one they had and i realy dont think they will be getting another real soon . and if i get it from a regular late model junk yard it would cost alot more . but i will try to remember to do pics when i get started .
that would be great because there's been so much talk about this conversion. and so far nobody has really proven how and if it works. if it does then i will gather everything i need to do this to both my fairlane and my girlfriends 55 wagon.
Bringing this back! Got my '99-'04 Jeep Grand Cherokee box last week. Now looking for a 55/56 MS steering arm to investigate fitting it to the Jeep box...
has anyone installed power steering on a flat head and worked out the bracket and belt problem for a 53 ford
I'm still planning this conversion, gathering parts now. I'll update when I get it done, but may not be real soon.
