So my 90's steering box/gear is leaking from the pitman arm. I think it has a tooth broken in it very sloppy steering even after alignment. The truck was hit 2 owners ago, ergo.... the bent frame.... so I was looking at napa since my friend gets everything at a cheaper rate then us supposedly. I noticed they sell manual steering gears has anyone ever used on on a ranger? Are they real nice like the manual racks in the foxbody? I have an opportunity to get powerdyne blower cheap so I would have to change things up a bit. I would like to eliminate unnecessary accessories if I can.

Is the manual steering box larger than the power steering box?
(Oil filter relocation clearance)
Will I need to change any other things?

The manual box is actually smaller

The input and sector shafts are different from the powered gear, so you'll need a manual pitman arm (1" - 32 spline) and a manual steering shaft. I made mine from a Cherokee as they have the same splines (3/4" - 30 spline)

Found a 3/4 30 spline shaft on a Jeep Cherokee today. Luckily the DD shafts between an '89 ranger and first gen Cherokee are the same and it made for an easy swap.

Power vs manual

Both shafts shortened; left is Cherokee and goes to the steering box, right is Ranger and goes to steering column

Completed shaft. I used the rangers shafts' plastic inner sleeve fitted over the Cherokee shaft and rubber outer sleeve on both

Years ago I had a 2wd B2300 that had manual steering. It wasn't too bad, just took a lot more effort to turn the wheels at a dead stop. That was my main complaint, once you get moving, it's fine.

About what year Cherokee?

1990 or so, the older generation.

Most GM and Jeep from the 80's-90's used saginaw boxes with the 1"-32 sector shaft and 3/4"-30 input shaft, so parts are easily found in junkyards along with from places like Borgeson. I am using both the bottom steering shaft u-joint and pitman arm for a cherokee on my manual box, though combined with an electric power steering motor from a Saturn Vue.
