Upper Wishbone Design.
Angel Acevedo - 25/7/17 at 01:01 AM

To the collective,
I am fabricating my wishbones, front only as Iīll be running a Live Axle in the back.
I was going to go with this first....

But found angle was a little bit extreme at the weld to the threaded insert, then I decided to use this approach even though I am using Top Hat bushings instead of Rod Ends.


Question is:
- Are there any considerations against doing so?
I donīt have to comply with IVA or SVA or the like

Also, I will have only full turn adjustment on Camber and pretty much Fixed Caster. Considering 11" (275 mm) distance between lower and upper balljoints, and fine threads on the Track Rod End used as Upper Balljoint, I get about 5° for 1" (25 mm) full travel which leads to 0.25° per turn Camber adjustment.
I donīt see it being a problem, Do you? if so, could you ellaborate?


Thanks in advance

I made mine with a curved design because it seems to "fit" around the spring

and in my opinion looks better.


Make sure you make them with enough castor.

do you really need camber adjust? Could you not use inline rod ends, or shims?
You'll get a stronger, lighter wishbone if you keep the forces between balljoints inline

Camber adjustment will be made through thread of Upper Ball Joint Shaft (??)
I will not be using ball Joints on the Chassis Pivots, Iīm using Bushings.
My question is regarding the manner pipes are joined together.
On the first example, there are only 2 pipes per wishbone.
On the second there are four, but angles coming into the threaded tube where the Upper Ball Joint will screw in, have a less acute angle, therefore easier to cut, fit and weld.
I decided to go this route.

design on first pic is imo much better in terms of strength

First picture is better. Second just has more cuts, more welds, and is harder to make. Its only done that way to allow threaded rod ends to be used.

Decided to go this route..
I was halfway through the pipe cutting and decided to end up with fewer welds...
So started from scratch and cut four long pipes to do first design.

Thanks all for your comments.
