Saginaw Steering Box Restoration/Rebuild
ฝัง
- เผยแพร่เมื่อ 24 มิ.ย. 2021
- Another Jeep restoration video. This thing was super rusty and leaking a bit, so I thought it would be fun to restore it. It wasn't in super bad condition, but it was covered in oil and grime so I figured I'd make it look a little nicer and replace all the seals so it wouldn't leak anymore.

I'm a retired ASE Master Technician and I have rebuilt many a Saginaw steering gearbox. It can be found in GM and Chrysler cars and trucks of the heyday of Detroit car manufacturing. It is the best design of that era, but was made obsolete by the rack and pinion. The Ford gearbox is a copy of the Saginaw: It is absolutely identical in design.
At 26:48 you show on screen, "properly adjust this nut per maintenance manual". It is a critical adjustment and I'll tell you why. First the adjustment. You need an inch pound torque wrench for this adjustment. Measuring the effort it takes to turn the stub shaft, turn the adjustment screw clockwise while moving the rack back and forth over center until you can feel it begin to bind as it goes over center. This is because as the adjustment screw goes further in, the tapered Pittman gears push the piston assembly into the other side of the cylinder. The specification is for there to be an additional 12 inch pounds (if I recall correctly) to move the stub shaft over that center. Lock it down. This adjustment comes into play when the front end alignment is made.
So why the "bind" in the center of the gearbox's travel? It is so the front end alignment can be set with 1/4 to 1/2 degree LESS caster on the LEFT side of the car to compensate for road crown. A modern alignment mechanic that works with modern cars that have rack and pinion steering gears might say, _"But that will make the car pull to the left into oncoming traffic!"_ That would be true with a rack and pinion car. But an experienced mechanic who had a properly adjusted Saginaw steering gearbox would know how to set the toe-in to avoid that pull. He would set the toe-in so that as the car was traveling in a straight line, the steering wheel would be 1/2 degree to the right so that any pull coming from the caster angle would be running up against the bind in the gearbox. That little bit of resistance inside a Saginaw gearbox was DESIGNED to make it possible to have a car that pulls a little bit to the left to compensate for the commonly heavily crowned roads of the 1950's and yet one that won't go over center, as long as the mechanic fully understands the equipment, knows what he's doing and properly adjusts the alignment.
I absolutely LOVE the way an old Buick Electra 225 handles on crowned roads when the front end is properly adjusted, and that's because of its Saginaw steering gearbox.
Great reply, the B bodies of that era all rode like Cadillacs. Loved them.
Here's another little tid-bit for you guys who might be interested. At 14:54 you see him pop the stub shaft out of the spool valve. If you look closely you'll see it has a pin holding the torsion bar inside. It is the thickness of this torsion bar that determines how much effort, and therefore how much "road-feel" the gearbox will have: The thinner the bar, the easier it is to steer and the less you'll feel from the road. You can't see the bar, it's inside the stub shaft. Some performance cars and trucks it's about 1/4" thick, on a '68 Cadillac Brougham, 1/8" and you can park the car steering with your little finger.

probably one of the most insightful youtube comments i've seen in a while, even though its a year old haha
I am thoroughly impressed by your knowledge sir. I have a 64 Imperial LeBaron. (made by Chrysler) Does it have the this same Saginaw box? I just had the box on my car replaced. I didn't ask the shop the specs. I was going to have the original one rebuilt but they recommeded a new one rather than have to deal with the possibility of problems with a rebuild. Thoughts?
I actually like That You Don't Use Music In Your Video's
Natural sounds is better than music 👍🏼
@@mgmesh8533 do. Çfdddfffffff me. ..... . BH vv vvvvcvvvvvvvvvvvvvvvv😅
It’s relaxing
Started GM dealership 1979. Needless to say we were the rebuilders of everything. I had the tools needed to do this job. A spanner wrench and a center shaft stub. You are supposed to remove large plug first, and then 1 inch nut or plug. The shaft would allow removal of spool valve while keeping all the balls in place.. Yes there is 22 balls. 11 shiny and 11 dull. Using the shaft allows you to stack the piston with balls then install in housing. Your way worked, but one ball out of place and you get to start all over again... Nice video...We rebuilt the 800 and 600 series gear boxes. The 600 series was the smaller ones with round top cover, you know the one that always leaked. Don retired.
Seeing your videos gave the encouragement I needed to try fixing stuff on my car myself. Its saved me a ton of money and is so incredibly gratifying. It always leaves me feeling proud of myself and what I can accomplish.
I'm looking forward to future videos!
The cherry on top was putting the original label back on.
That really made me smile.
I love watching a craftsman at his best. Outstanding work!
Thank you for showing the whole process of getting the arms off of the box too. Most complete video out there
Irony - I am watching you from Saginaw, MI & I live 1 mile from the plant that steering box was made.
Watching you work is so effing relaxing I wish I had the challenge and patience for the amazing work you do God bless
Super nice work there. Holy Smokes, that is a lot of seals! A very intriguing design.
3:29 I've only ever seen diagrams of the insides of a recirculating ball steering box and never imagined that the recirculating ball mechanism would be a U shaped tube split into 2 halves of bent metal.
Great work. 🔨🔧🔩
Thanks so much for sharing. 😎👌🏼
fords are a split tube,. that can open up,like mine did.. non power.. probably why..
Would love to see all the Jeep vids in a playlist. Super amazing to see someone taking the time to restore the parts than just get new. Gives me inspiration for my project XJ. Think I'm gonna try and refresh the axles myself, using your video as kinda of a guide of sorts. Keep up the great work.
While that's a decent idea, get the factory service manual for your rig and follow that, it'll show tolerances, torque specs, and more, stuff that is vital to get right
What Is a jeep video?? Greetings from Italy
@@wop60 the vehicle this component is from is a jeep, and this person has made several other videos about his jeep. Hello from not italy.
@@levivaughan3434 thanks for explaining from not Italy

As an aspiring mechanic I find this super interesting, satisfying, fun and educational. Absolutely great video! Leaving a like!
Nice job, I never had the patience to do it or would of as I tangled with everything else so hats off to you
Looks pretty complicated. I'd leave it to somebody in the know.
never saw this kind of rebuild done.enjoyed watching.thank you
Greetings my dear friend....
In fact, I would like to thank you for this beautiful video because you never entered music...Never.. How beautiful it is to make the sounds of nature speak ❤️ and not the ugly music and song for example...
We want to see and hear the sounds of the tools that are used and made 💐 What a beautiful feeling 😍😍😍...
A man who doesn't waste time with words but results.
Damn i love the simplicity of a steering box!! Damn fine job!
Maybe I'm biased, but it seems more complicated than rack and pinion. A whole lotta extra parts that can be tossed with one of those things.
I downloaded this video and literally watched it step by step to rebuild my steering box, greet job
Quality craftsmanship right here folks!
This is the best reconditioned st.box video I've seen. Dam nice work Sir.
Beautiful resto! One of my favs.👍
I love you jeep videos I have a 98 XJ that needs a lot of the the stuff you've showed thank you!!!
impresionante trabajo, realmente impresionante!
en verdad, nunca me canso de mirarlo!
maestro, recibe un gran saludo desde República Dominicana!
Very good upload as usual. Thank You.
Nice rugged Ridge heavy duty steering, I have the same one on my 98 xj, awesome video, super jealous on the rebuild steering box, came out better then factory....⭐⭐⭐⭐⭐
Very detailed in restoring the engine, very useful for mechanics, greetings from Indonesia 🙏
Excellent Craftsman. Great Job!
By far the most quality and conscientious steering box rebuild ever. Wont find that good of a job in a rebuilt steering box from your local auto parts store.
A absolute pleasure to watch...
Such care and attention to detail...
I always love how your projects turn out!
Nice set of tools also. I have several of the old Craftsman quick release ratchets and I love them. Mine are stamped Patent 1971. They are getting rare. I managed to find 1/2, 3/8 and 1/4 inch drives in good shape.
I bought the first one, 1/2" drive, brand new in1973. 50 years, wow.
With the proper tool, these repairs are child's play and a delight.
I love powder coating. It has to be one of the better tools available to restoration. And there are so many colors to choose from.
You did an amazing job!
Complicated but you did an outstanding job. 👍🏻
I come here for the peace and quiet…. This guy is a Jedi. Best part of the web. 👍
My Daddy once said that everything that hits the floor has to be picked up eventually!! LOL!! Love your video!! Please keep them coming....
Your comment made me remember once while repairing a watch I dropped a c-clip the size of a pin head on the same color carpet. I didn't think I would ever find it but I did & right away.
Огромная, качественная работа! Спасибо за контент!
nice job bucko, i’ve done 3 of these on my jeeps and they can be a little challenging, you have to be pretty organized. You did a great job.
i’ve only had to replace the bearings once, they are robust and don’t see the kind of pressure and abuse other bearings get.
The cast housing usually eggs out before the bearings give up
Excellent Work Absolutely Stupendous Job Great Stuff I think I leaned something today Cheers.
That was amazing. Wow.
Awesome how to! Well done!!! You dealt with all the issues I needed help with mine. Thank you!
Nice torque wrench “ impact impact ---click”, you gotta love it!!!!!!!😉😆
Perfect rebuild. Better than new.
A little heat even from a cheap propane torch would have helped get that pitman arm off without cutting it
It was going to get replaced anyways. So why go through the trouble
Legally can’t use heat on any steering parts. It can fuck uo angles and such
@@kalebolson9710yeah, no, that's not even a little bit true, nor correct.
You're not heating the metal to a pliable working temperature, much less a melting or bending point. You're just getting it hot enough to slightly expand and get it to temporarily loosen its grip on what it's attached to. Once it cools, it is still within spec. You can witness this happening on an alignment rack. Grab a torch, heat up all the control arms and watch the toe spread apart a few degrees... Then watch the toe "snap back" to memory as it cools like nothing happened.
You'd spend a fortune replacing steering parts every time you needed to make an adjustment if you were always afraid to heat it up.
I agree.I used to be a motor mechanic.I was very surprised.And then what do you see,a blow torch.Had the heat all along.
That's totally right, I don't understand why didn't he think about that easy one!
It's been a while since I have seen a pair of spanner wrenches good job man keep up the good work
Outstanding video!
У нас в России много XJ, я сам полностью отреставрировал джип 94 года! Наслаждаюсь им! Видео 👍
I don't have high blood pressure, but if I did, videos like this would cure it.
Now you made the tutorial! I needed it 3 years ago 😂
I’m impressed!
Nice lighting & camera work !
Why is this so soothing?
Your “don’t @ me” subtitle had me dying!
I just watched a master class in dudeism.
Loved and subscribed my guy
ОГРОМНЫЙ ЛАЙК за порошковое покрытие корпуса!!!
A HUGE LIKE for the powder coating of the case!!!
Nice work Sir!
Youngstown Automotive Group
Great video you made it look easy and all while trying to film again great job. Im actually partial to your jeep series of videos as me and my dad both like jeeps specifically the Cherokee line he had a 90 pioneer that he bought in 92 and drove it until 99 he passed away in 2014 before i could get mine I've got a 95 sport with 230k still starts and runs like it has 50k and I've some work to deal with on mine mostly cosmetic though
Okay
very nice clean job!
Very nice rebuild 👌
Sweet rebuild and rig there bud...
Great job sir 😍
We made that gear housing at Saginaw Malleable iron foundry.
My Grandfather worked at Malleable iron & my Dad worked 38 yrs. at Saginaw Steering Gear (on Holland) plant #3... I knew I'd see someone from Saginaw, Mi. on here...
From Saginaw MI as well, saw Saginaw in the title so I clicked to see if anyone else was from here.
never seen one of these rebuilt. nice
Na,
the bolt had to be removed from the clamping part for the gearing! But you should have known as a mechanic that a groove is milled to prevent the shaft can slip out! Well disguised in the next picture!
Many greetings from East Frisia in Germany!
Great job man you got me to sub. You remind me of cool again restoration
A rare look behind the camera there too :)
Beautiful work, looks like I will be doing my ow rebuild instead of purchasing one, Thanks.
Excellent detailed video . Watch it . Great Video
Wooww, verry relax video. Thank you very much.
Hey guys, great job nice video
excellent restoration
really like it to see this job!
Good job mate 👍
The finished product will be stunning
Excellent work
Show!!!!!!! Congratulations!!!
Plz do more videos like this I absolutely love them bc I'm a mechanic
Good Lord, what a complicated setup. I've never seen anything like it. No wonder you needed a workshop manual !!! Well done.
Wait till you see the insides of a transmission.
Perfect Job!!!
Good use of the tools to verynice work
Good lawrd I wish I saw this last week! looks exactly like mine!
That jeep is going to be perfection
beautiful work
Great video. Thank you.
Strong work !!
Dang! Quite a project for sure. I've never opened a steering box. I'm thinking very few shops anywhere would be aa meticulous as you. 👍👍
That's only cuz they aren't on camera with hundreds of thousands of people watching 😛
Most shops won't even rebuild a gearbox. Unfortunately, due to the time it takes to remove, rebuild, and reinstall, it's more cost-effective for them to just replace it with a remanufactured box.
The only real value in this is if you're doing the work yourself so then you're saving on the labor cost.
Great job!!!!!!!
Hats off to this guy
Nice work 👍❤️
Great video👍
This is so satisfying
Reminds me of my 95 XJ when my son rebuilt the front end.
Automotive poetry!!! got to rebuild mine too, CJ7 jeep.. thanks!!!
As I am watching I am thinking while you where tearing it down thinking I wonder if that Box can be powder coated and sure enough you powder coated it, very cool, and I did not know the front caps on these boxes where aluminum and could be polished, very nice!! I still won't RR my own I just hand in a core and get already done, but you knew what you where doing,
Good job. I noticed at the end of the clip that the car needs a steering wheel. There is a deflection in the wheels
"What's the torque spec for this?"
"3 Ugga-dugga's"
Little bit of heat with a mapp gas torch always lets the pitman arm come off...
Anyways, you did a hell of a good job on the rebuild.
Believe it or not, melting a crayon on the splines above the pitman arm helps too. I didn't believe it myself until an old mechanic told me that trick and I tried it and it worked.
