Re: Rear Panhard Bar ?
I'm going to disagree on this one. The roll center on a torque tube rear end runs at the height of the universal joint. The roll center with a Panhard bar is where a line directly up from the axle crosses a line from the center of the u-joint to the center of the Panhard bar. Basically, this is right at the height of the Panhard bar, a good 6 inches above the u-joint. The closer the roll center is the the CG, the lower the roll. 6 inches is a pretty good improvement.

Re: Rear Panhard Bar ?
The backend can rock side to side on the rear spring shackles . The panhard bar holds the rear axle steady on sharp turns

Re: Rear Panhard Bar ?
" ... The roll center on a torque tube rear end runs at the height of the universal joint."
That's up near the gearbox and chassis rail. "The roll center with a Panhard bar is where a line directly up from the axle crosses a line from the center of the u-joint to the center of the Panhard bar. Basically, this is right at the height of the Panhard bar, a good 6 inches above the u-joint. The closer the roll center is the the CG, the lower the roll. 6 inches is a pretty good improvement." That's half way between the diff and chassis rail? The center of gravity will be higher for a sedan than say a speedster. |

Thanks for sharing drawing ! Is there a set distance/location on the right frame rail where the bar attachment is shown ? Or, can it be randomly placed in the general vicinity shown In drawing ? Is the length of bar set, as made and sold by vendors, or is a longer bar better ?? |

Re: Rear Panhard Bar ?
Can't see it? I see it... I can even see it in your post. If you can't see it go to my picture album.
https://www.fordbarn.com/forum/album.php?albumid=3320 https://www.fordbarn.com/forum/pictu...ictureid=39757 Hardtimes, that drawing is Bass Ackwards. The Panhard bar available form the vendors mounts to the LR shock mount and the center section of the rear axle. Last edited by Y-Blockhead; 02-15-2018 at 03:22 PM. |

Re: Rear Panhard Bar ?
Dunno about the aftermarket Model A panhard bars, but as to a general bar, the longer the betterr so to minimise arc length change movement.
And the bar should be up hill to chassis a bit ( in height elevation) at normal riding height loaded, so its working life going over bumps is in the best arc. |

Re: Rear Panhard Bar ?
Thanks for your efforts, Y Blockhead but I can't get to see anything on the album either - never have on this forum. Don't know whether it's something I should do here or something should be done behind the scenes.
Does anybody else either have a picture or have a suggestion as to how Y might be able to load the pictures?

Maybe check your "profile privacy"? |

Re: Rear Panhard Bar ?
Well sorry guys. I never had this problem before. Maybe it has something to do with the Ford Barn server upgrade?
Sooo, let us try Flickr... Please let me know if this works. I can see all the other pictures I posted just fine. Last edited by Y-Blockhead; 02-15-2018 at 07:50 PM. |

Re: Rear Panhard Bar ?
I followed this Panhard post from the beginning. Having driven our 1929 Tudor for 50 years, at 45+ mph on the country roads, the Tudor can be a real challenge to keep it on our side of the road. It always dips and dives all over the place. It has all new spring shackles, shock absorbers and the tudor is in great shape. I ordered the Panhard from Snyders (on line) on Sunday and I received it on Wednesday by USPS. Cost plus shipping came to about $150. It took about 30 minutes to install and then I test drove our Tudor. I just got back from driving on the same country roads. The Tudor showed about a 90% improvement on the dipping and diving. Body roll was greatly reduced too. It was money well spent.

Re: Rear Panhard Bar ?
So it is only a half panhard bar.
Not as good as a long one but better than nothing. I sometimes wondered if the side it was anchored to chassis mattered re RHD and LHD cars. . The RHD OZ car I copied mine from was anchored on left as well. |
