Ball joint removed from securing point on frame. Unbolt the bushed end of Panhard rod from the locating point on the axle. In this case the securing nut is easily fitted as it is welded to this locating tang.
The adjustment nut on the Panhard rod can now be tightened up. Add grease to ball joint, take vehicle for a test drive and get a wheel alignment if necessary. Phil Lord.

I fitted these over over 30 years ago. They really sharpened up the cornering. Here's the one on the rear. Stueeee , Nov 26, Joined: Dec 10, Posts: 6, Profile Page. Not leaf sprung, but mine works well. Danny, please be mindful the rear will travel up and down in an arc.
Less pronounced with a long bar. Also it should be level when the car is at rest so the rear is centered. Joined: Sep 16, Posts: 8, Profile Page. My new 41 truck has recently installed parallel leafs and I inquired with several local builders about installing a panhard rod and they all said it wouldn't be necessary. My 34 ford with semi elliptical leafs however does have a panhard rod to the QC. Bandit Billy , Nov 26, Joined: Jul 20, Posts: 8, Profile Page. It was a long bar to minimise the suspension arc however under compression the rear axle would move slightly to one side, where attached to differential housing.

As this bar sets now, it would tend to move the axle left and right depending on the bump going over a bump would push the axle to the drivers side; a pothole type dip would push it to the passengers side.
Did I understand this correctly? Joined: Jul 27, Posts: 6, Profile Page. Seem like the panhard bar needs a bend down near the chassis to get it back level.
It will have to be remade since the bend will make it shorter. The longer, bent bar would actually 'grow' as it fell and keep the rear located under extension, compression would have some movement but if you play with the 'bend' you can minimize that as well.

This triangulates the system and eliminates the need for a panhard bar at the axle. WelderSeries , Dec 16, Joined: Apr 3, Posts: Profile Page. Once the weight of the vehicle is added the frame will come down and the bar will be level. Even so, that amount of angle in the bar is not too bad.

I am new to this forum but have been building road race cars for quite a few years. It is all made to make your car handle better. As for a buggy spring type rearend, I personally believe that a watts linkage would be better because it keeps the rearend perfectly centered no matter what the suspension does and a panhard bar does nothing more than help center the rearend from moving right or left and if not setup properly will make the car handle worse than nothing at all. To understand why the mounting location of the panhard bar effects cornering balance, it is first necessary to understand how engine torque and roll center height effect oversteer and understeer.
The engine rotates the driveshaft counterclockwise viewed from the rear. That rotating force is transferred to the axle. As a result, the axle also tries to rotate counterclockwise and weight is transferred from the right rear wheel to the left rear wheel.
So, if all other conditions are equal, there will be more weight transfer at the rear wheels in right turns because the weight transfer from the engine torque is added to the weight transfer from cornering forces. This increases the car to oversteer in right turns. The car could easily be rocked from side to side weight would roll from one side to the other. In the rear of the car, if the jackstand were moved to the right then more of the cars weight would be placed on the left side of the jackstand.
If the jackstand were moved to the left then more of the cars weight would be shifted to the right of the jackstand. FMI Knowledge Base. Search this site. A Glossary of Quarter Midget Terms.
