Some one said, there is a company that makes a front steer ball joint with ackerman corrected. I haven't found it yet.... Edit...... I noticed I didn't put the updated pic of the tie rod end. There is actually a 2" spacer in between the steering arm and heim now to remove bump steer.... Last edited by R5P7Duster; 12/30/09 09:45 AM.

Very common swap, been done in Oz for years using a Holden rack which gives no bump steer issues, etc. What model Holden? & what coupler to the stearing column any info thanks. drag345

And used a stardard Holden steering coupler, shortened in the middle abit You do have to swap the lower steering shaft in the steering column to Holden too, or the entire one if you machine a circlip groove in the top for the bearing.

FWIW I feel you are not comprehending the good advise given based on your last question to HemiFred. You cannot change from a rear to front steer by simply exchanging a few factory parts. Your proposing undoing proven critical steering engineering. What will you benefit? And at the cost of your and someone elses safety. IMO Bill Reilly and BondoBob (maybe others too) have adequately validated their front steer systems. Don't attempt it on your own on a budget (both money and fabricating resources) because you are not only putting yourself but others safety at risk...

Thanks drag345 I never weighed it all... I actually have the steering box and all the linkage out of my Charger still and a setup out of another VJ I wrecked too around...and have a couple Holden racks around The racks are easy to get to, but the steering box and stuff is kind of buried My K frame was from Paul Norris by the way I just got the K frame from him, then a rack and steering joint plus column shaft and put it all together over here. Here is the coupler mod I did (got a couple extra couplers, just incase ) 5713092-newpics485.jpg (181 downloads)

The answer is no. My front uses all factory parts other than the rack.my spindles are from an early disc brake I think by Kelsey . the lower arms do not fit on later spindles Fred looks like the lower balljoint arm got A little hot at one time for the push toward the tire

I have cut the steering arm from the ball joint then made the new steering arm that bolts on using longer ball joint bolts. This arm moves the tie rod joint the same distance outside the ball joint as it was inside (stock rear steer). Hard to describe in words. We'll see how it works about March?
