C'mon now, you used a colon for punctuation.

You cannot use a panhard bar and a four link set up without binding. The panhard bar is actually working against the four link's natural path of travel.

[Hacksaw707]

Naw, I just tried to do one of those cool sideways sad faces all the cool kids do when texting, but failed.

And yes you would think it would be binding.......yet it's not, until right at the very end of suspension travel. It may be wrong but it does work.

[EeePee]

Coughain'tright....

[stelerzman]

Doesn't a Jeep JK have the 4 link with the panhard in front and the same for the rear with the exception it's called a track bar?
What's the difference between panhard and track bar? It serves the same purpose, right?
Didn't ford install them in the '90's?
I have seen some of the 1:1 foff rigs with them, front and rear.

Thanks

what kind of wheel hexes do you have on the rear?

Not sure they came on the axle when I got it.

I need a parts list please Sir, I think I found the base for my ultra4 build. I might have to bug ya for more info come time.

Thanks man.

Hey very nice craftsmanship! What rear axle housing is that?

Rc4wd aluminum centered Wraith.

Jeep Is a parallel 4 link, Hacksaws thingamajigsawpuzzle has a triangulated 4 link.

I like everything but the panhard bar though

[stelerzman]

I like it.

If you ask me (which you didnt lol) here are my opinions:

Truck looks badass. And looks ready to go fast just sitting there!

Parallel 4 links with a track/panhard/centering/axle swing control bar are where its at. So rigid, and you can control the movement of the axle in any axis based on link length. Only thing better would be a Watts link, but thats a lot of work for an RC vehicle where it really doesnt matter what the geometry is as long as it works ;)

Now, if you built a solid axle, IFS 2wd truck for drift, road race or all out speed, Watts would be the ideal setup for the rear. But meh, we haul it in the dirt. Consistent pinion angle is about all we genuinely care about hahaha

Dig the beginning of this project. Keep the updates coming.

Well after a better look now I'm home all i can say is......


there are 2 screws missing out the front underside



But that chassis and layout look awesome

It's ok for you say how you really feel


I been getting killed all day for a panhard bar on a sloppy 4 link set up.

[M1tch]

ignore them (and me) lol. its your build, not theirs.

[stelerzman]

Just lable it as a track bar and forget what the Bitches are saying.
Hey, if it works and doesn't bind in any way shape or form, then who cares what people think or post. This is your project and if your happy with it and it flat out works, than F 'em. It's your $$$$ & your project.
Gooooooo foooooorrrrr iitttttttttttt.

[WHITE-TRASH]

That is one sexxay rig you're building. If your dual triangulated 4 link is sloppy enough to need a panhard I'd be looking into some raised shock mounts to bring the lowers back out to their proper location to increase their triangulation.

If you insist on (wrongly ) running a panhard with it as is then lower the frame mount and/or raise the axle mount so it sits level at static ride height. That will minimize the side to side sway.

[doublej]

Y'all are missing the point that his backend doesn't bind. It has limited travel.......

Internet arm chair suspension geniuses - gotta love em.

[stelerzman]

Why don't we let him him get it built and running, then we'll all see what works or doesn't work.
I have faith it'll work out in the end.

[monkeyracer]

I think I am confused about why it doesn't bind because math works everywhere except on this vehicle according to the OP.

Make a right triangle. Any right triangle. Now keeping the hypotenuse the same length (that's the long side, for the backwoods hicks ), change the angle of one the two non-90 degree angles, and tell me what happens to the sides of the triangle? The side opposite from the changing angle gets smaller as the angle gets smaller, and the other side (known as the adjacent side) gets longer.

What that all means is that as the suspension in compressed, and as long as math is still valid, the axle WILL push to the left. Now, add in the two triangles of the upper links, and there has to be some binding. If you can't feel it, just wait until you are at speed and take a huge jump, it will manifest itself there.

Basically, the triangulation isn't working if you have axle sway. Period.

Try this: remove just one of the upper links. Either one will do. Now cycle the suspension and tell me that it isn't any smoother than with the 5-link version.
If you think it is the same, then somehow you live in a math-free vortex, and maybe I should come to your house to do my taxes to try to get more money from the gov.


Beyond that, I think it looks great, and would love to see what you do with the tube work, etc.

[doublej]

I'm gonna be honest - I didn't read your post because your not reading his......

The rear end has limited travel. Meaning during the motion of travel it does have it does not bind.

It may be hard to tell on a RC rig but go built a couple 1:1s. Things don't move as much as you think they do. During the travel of the axle it will actually take quite a but of shock stroke before the axle starts to move side to side from the panhard bar acting on it.
Now do the math - most kitted out 1:1s use 14in or bigger coilovers. What size does most scalers use and what is that in comparison?
