Post Dropped axle+rack and pinion?

I've been wondering this for a while. Can a mustang II rack and pinion steering unit be used on a dropped axle nastalgia from end? I've never seen it used, is it just because its not nastalgic/original to that front or is there some technical no no?

A rack and pinion gear can be used with an axle but it should be mounted on the axle. If you mount it to the frame the short tie rods will cause excessive bump-steer. Mounting the R & P gear on the axle eliminates bump steer completely. The problems, albeit minor, will be the U-jointed shaft from the steering column to the pinion and achieving proper Ackermann (sp?) angles.

It will work fine, but you will need to use a telescoping sleeve in the steering gear, to allow it to float up and down with the axle. I was involved in such a project a few years ago - I think the owner of the project purchased the telescoping joint from Posies. They made a few to sell, after Posie built his famed fantom woodie that used that setup.

SirSpeedy....Good point, Thank you.

Older Ford Pintos have a slider shaft in the steering columns and some decent U-joints too. This set-up works well and is cheap also.

Riding on your original message, are you going to keep the original steering column? I want to install a Hiedt's Superride II in that '40 to the left but keep orignal steering column. Borgueson has all the linkage but I can't seem to resolve the initial column to u-joint connection. If you have I would be very interested in how you did it. thx.

Raw, first I'd like to say nice ride. Second I'm not using the stock stearing column. I'm using a stearing colunm from a '77 trans am with tilt. I hope you get it figured out.

SirSpeedy and SJfast thanks for the help, I'm going to raid the yards in search of an old pinto.

Thank you for the compliment. It is a fun cruiser but can't wait to replace the 4" dropped I-beam with an IFS and Rack & Pinion steering.

Good luck on your project.

This is a set up that I am very familiar with. I used this same set up on a 71 Vega C/gas car. It worked perfectly. I used all slip tubes for the steering shaft and after the first run and feeling the steering wheel go down I never paid any attention to it afterwards. Car ran straight and handled beautifully. Had the Rack mounted to a 4" dropped tube axle......GK
