Front spring going through radius bars

It seems as though you have to join that sight to get any info. At one time you could get a lot of info there but not anymore.

That is true, Jim, for they don't want everyone to know how to build a T-Bucket safe or give away any free info. I am a member, and just don't get not helping another guy out on a build project.

Yes found that out when i tried to get on the site. I have read about it on another link somewhere some time ago.

Yeah, you do have to register but it's free. I read the article and it is worth a look.

After ranting last night, I got up at 0300 today and did some research. I can't find anything to support my idea that behind the axle is better than in front, and we've all seen plenty of buckets with the tie rod in front. I may have dreamed the whole thing. Either way is an approximation of perfect Ackermann, which is plenty good for everyone except racers, who get very excited about suspension geometry since they are running high speeds, abrupt maneuvers, and tires just barely holding on. NASCAR drivers earn their pay.

If you're obsessed like me, there is also 4-wheel Ackermann, used in industrial vehicles with heavy loads and tight turning required. The rear wheels turn opposite from the fronts. Honda tried this some years ago in one of their car models. I drove one and it felt creepy; the damn rear end had a mind of it's own.

I know that registration is free and at one time, a long time ago, I was a paying member. After getting information that helped on my build I did not renew because of all the political hacks that were on there. Perhaps it is better now, at least I would hope so. Keeping all that political stuff out of this site is one of the many things that make this sight so appealing. IMHO. There are plenty of sites that cater to that and I have no problem with that, I just don't like it mixed in with car stuff.

In my opinion ,the Ackerman thing is important but quite often overdone. If you get it perfect thats great but if its close you or your car will not know the difference. Ford pickups in the 90 and some years newer used the same steering arms on several different wheelbases ,the ackerman on the crew cab long box would actually make the sidewall distort on a tight turn.What i'm saying is if you run the line back and its within a few inchs of meeting don't spend a lot of time and money trying to get it perfect.I would rather see someone spend the time on bumpsteer ,way more important to me.
Like I said just my opinion.

I agree, if you check some of the new cars from the factory there probably way out ,and you would never no it.

...and the diagram we use, with the lines meeting at the rear end, is only an approximation of perfect Ackermann. I've never seen a linkage or other way to achieve perfection. If we have any mechanical engineers, there's a good problem to make you crazy.
