'03 Mastersbilt build suggestions.

What about steering racks? I havent heard from the PO about the parts he has to sell so now im looking at a Woodward rack another forum member has for sale... 4.0 ratio i believe. I havent used a Woodward since the 80's... they look nice but the parts are pricey but arent they all....

This is very general (if you can't get info on what is supposed to be on car)

The rack will typically be 1/2 to 3/4" longer (between tie rods) then the distance between the lower control arm mounting holes. Example if the lower holes are 18" apart, then a 18.25 to 18.75" length rack is generally used.

Rack ratio: sort of a personal preference, but typically the shorter the steering arms are you probably want a slower rack and vice versa. Ratio's have gotten a lot faster over the years and 4.0ish or faster is more the normal, but if you have long steering arms (around 5" verses 4.5") you might go up a little to a 4.4 to get similar speed as the short arm spindles.

For sure try to get a rack with the vertical slots, Just be aware there are different ends, some are more around the top of the shaft, some more at middle and some that are more below the shaft. Which one you need can vary depending on car. Now granted a lot of older cars don't need the slots because the tie rods are meant to be above the shaft so the old non clevis racks work fine for the most part.

The rack I'm looking at is a 3.66... I think I can retrofit the slotted ends. Definitely a plus for adjusting bump steer. Not sure on the servo spec. I'd really like a faster rack ratio... the one on my '95 is 3.3 something. I could replace the pinion on the Woodward if it's new enough... they don't service anything older than 10 years or so. Different model. I like bigger steering wheels if I can get my fat gut out of the way.

I guess the mods dont even look at the tech section any more......

[Krooser]

Yep...you are correct. I sent ModJr1 a message a few days ago.

I see Wehrs makes an adapter to put slotted ends on a standard rack....anybody use them?

It's gonna make your rack length a lot longer.

Use just one and shorten the tie rod? Shorten the rack and drill/tap a new hole?

Changing the tie rod length could mess up your bump steer more than this part fixes it.

Yeah you're correct.

Back in the early 80's I was rebuilding my '69 Galaxie late model into a Torino. the car was an old USAC car from '61... I installed a '65 front stub, used Impala spindles turned around to fit the Ford rear steering box.

I spent dozens of days on a graph chart and under that car figuring out how to get zero bump steer. When I got it right I fab'd a custom center line using .060 1" DOM and weld on shock lumps.

The car debuted at Chilton, WI's little 1/5 mile banked dirt oval (which I would promote at 7 years later). Anyway I ran a ten lap heat race pushing like a dump truck... when I pulled into the pits, and hit the trailer ramps, the center link fell off!

So much for zero bump steer AND light weight steering parts!
