All I'm gonna say is if you are gonna do a 3-link, you must understand how and how much you are loading the ends. Disco axles aren't as cool as it may seem. IMO you have a bit more room for fawk ups with 4-links...but thats for next time
Ghetto Fab. said:Seems to me, and feel free to flame away, that people have gotten 3 links somewhat confused with 4 links. A lot of people seem to consider having to lower links plus an upper wishbone or A-frame as a 3 link, since there are 3 main parts. Whereas a true 3 link is simply two lower links and one upper LINK. Each link having only two connection points. Side to side axle location is done via a panhard rod or track bar.
The wishbone or A frame suspension geometry acts just like that of a triangulated 4 link the only difference being forces on the joints.
Anyhow, just hopeing to clarify what were talking about!

Yep. Thats why I think you have less tolerance in fawking up link loads.cmk said:There's one problem here; in terms of geometry and dynamics, a "3 link" must be modeled as a 4 link.
Afterall, a 3 link is nothing more than a 4 link with 2 links converging before they meet discrete mounting points.

Do the layout. Convergence points are gonna be similar between the turkey bone and a real 4 link. Recall cm"link bitch"k was talking about dynamics and geometry.Azzy2000 said:

:flipoff2:
I understand what youre saying and where youre coming from but this is a pointless debate... im just saying if its got 3 links, im gonna call it a 3 link for sure...LAME said:

On a rig, in the garage.:flipoff2:IndyCJ said:Ok,
So where would one start to build a three link suspension?
Bah! Smartass. :flipoff2:LAME said:

What do you mean? First step in designing the suspension?
I would say t-case to rear axle. Figure out where you can mount the links to the frame.IndyCJ said:
Bah! Smartass. :flipoff2:
Yea, first step in designing. What to measure? Where to measure? What factors you need to take into consideration when you measure? Etc.
How 'bout a group project? :flipoff2: I've got my rig setting in the garage (project, not yet complete) and say I want to do a 3 link rear for it. You tell me where to start, and I'll start measuring, and we'll design it 'online'. I'll take some pics, some measurements, and let you Jethro's start your gazinta's.![]()
