Trying to figure what is the best way to go with power steering conversion.
Who is using what and good and the bad of your setup?

Looking at ones with solid front axle not ones swapped to independent.

Should I use the factory location conversion or the swap using newer style front mounted box?

One of the easiest and most popular is the mid 80's Toyota 4wd box. Fits in the same place as the factory box with simple modification. Do a search.

If you give us your truck layout, engine, etc., size, it would help.

My truck is 55.2 GMC 150
2002 GMC 5.3 LM7
4L80E
Stock front suspension
Stock rear suspension with 9.5 in 14 bolt semi float rear 3.73 gears

I've got plenty of clearance for either setup I just wanted some opinions on how everyone likes the setup they have before spending the money to swap mine out.

I used a power steering kit from CPP for my 51 panel.
Also, upgraded the brakes to discs at that time.

No drama on the install and steered like a Cadillac. And, stopped on a dime.

I'm up for the disk brake swap but still working out details. Since mine is 8 lug its more of a challenge. Looking at probably using 88 up rotors on modified factory spindles. That will be my next challenge. At the moment steering needs to be decided on to determine which headers I use for clearance.
I like the looks of the CPP kit but I have access to 2wd truck steering box for the other swap.

I did Disc front. I did the power steering that uses an owner purchased Saginaw box on a 1956 GMC.

I'm using an 86' C10 Saginaw box with a kit from Brothers Truck. So far the only draw back I see is that you need to reinforce the frame at the mounting position. I am still working that out. The drag link and pitman arm were straight forward, just adjust the length and your good to go.

If you choose to use a CPP kit, make sure that your kingpins aren't worn out. The power steering gets swimmy if they are worn. This is annoying because it adds to the lack of road-feel inherent to driving with the Saginaw p/s box.
I removed the original caster shims and replaced them with 6 degree caster shims. This greatly improved the feel of the road. Now when I come out of a turn, the wheels return toward the straight ahead position just like the stock manual steering box does.

I can see reinforcing the mounting point. The GMC I'm working on has a much larger front cross brace engine mount than what is on a comparable chevy. But if going that route I will definitely beef it up , thanks.



I was told about the degree shims to help out with caster. But I seem to remember that only 4 degrees was recommended.
