I have been working on my front suspension on my jeep tj and i see some people dont use a panhard par with 4 link front suspension, so my question is what does the panhard bar's purpose if your running a 4link front suspension? It might be a newbie question but i have asked alot of people and no one has the answer so hopefully someone on here can explain to me the purpose.

your posting this in the wrong forum:flipoff2:

this is a suspension 101 question

search, google, pull your head out of the sand

if your asking people, and they CAN'T tell you, maybe try askin someone other than your girlfriends mom.

The panhard controls side to side movement.

If you are running a triangulated 4 link and full hydro steering, a pan hard bar is not needed. If you plan on running a steering box, stay with a 3 link/pan hard bar and set the pan hard to follow the movement of the drag link (ie same downward angle and keep the length of the panhard as close to the length of the drag link as possible). A few have done triangulated 4 links with steering boxes and drag links, but bump steer then becomes a major issue.

i run double triangulated with no panhard....i use hydro assist which helps with the bumpsteer but there is still some feedback....you get alot more unrestricted suspension movement out of this style of suspension but how much is really necessary...i went this route b/c it was just a little bit easier and seems to work good

hydro assist will not make a difference in the amount of bumpsteer that occurs - bumpsteer happens when the drag link goes up and over as the suspension compresses while the axle only goes up. The only way for the system to 'not bind' is for the wheels to turn or the steering wheel to turn

Ok so if im using a triangulated 4 link set-up i need to ditch the steering box, thats the question i have been looking for so i cant use crossover steering with a triangulated 4 link setup?

you can but youre gonna get bumpsteer. if you run it make sure you set up the drag link parallel to the ground at ride height

I hate bumpsteer i need a set-up that has no bumpsteer so maybe i should go with the 3 link with the panhard the more i read the more it sounds like the 3 link is the way to go to not have to worry about bumpsteer.

A 3-link does not eliminate bump-steer! Any system that uses a drag link (and thus has mechanical steering) must be properly set-up to avoid bump-steer. The only way to completely eliminate it from the system is to go full hydro (eliminate mechanical steering linkage).

Bump-steer (or lack of bump-steer) is effected by the geometrical relationship between the panhard bar and the steering drag link.

ok so i can run the 4-link with crossover steering as long as the geometry is correct.

i really wanted to do a 4 link on my tj in the front but it was not worth the extra work i am doing a 3 link with a panhard and it is turning out pretty cool and i am actually glad i did the 3

If you choose to build your own 3 or 4 link w/panhard you need to look deep in to the way every thing works and why it works. There is a lot more than a few links welded under a rig. If any of the setup is wrong there is a good chance a standard short arm kit will work better. Sad but true!
