Does your Spohn Adjustable Panhard rod rattle?

Well the rear end has rattled ever since I lowered it over a year ago. I thought it was the springs but today I dissmissed that theory. I pulled the rear springs and put a piee of nylon reinforced rubber tubing around the top coil and put them back in. Low and behold, the rattle remained. SO I investigated more and foud the sound to be coming from my Spohn Panhard rod. Not on the adjustbale side but instead on the other side. I tried to get a picture but my camera was being stupid and would not take a clear shot. I have the basic adjustable one and not the double eneded or spherical rodded one. Does anyones else rattle here?

which design do you have. it is very important the jam nuts are TIGHT. if they are loose at all it will rattle, and you risk breaking the peice.

I found a pic after all that came out. This is where the rattle is coming from. But the piece is not loose.

Yea they are as tight as can be. You can see the white paint on the pic that I used to measure how much I actually tunred it. Neither side will turn and it is dead tight. I may take it off and make sure since all the wieght will be off it.

is that picture your car?

if that picture IS your car, try putting the spherical bearing on the axle side, and the other side (if it is poly, if it is spherical also, disregard this) on the body side.

Yes that is my car and that is how it is installed. My digital camera took one good pic. That pic was taken with my head under and behind the passenger side rear tire. The poly side is on the car and the rod side is on the axle. Wait, I may be wrong. Is the body side on the driver side? The car is in another garage and I cannot go look. Anyways, I will double check that tomm when I go back.

Is there ANY play in the heim joint itself? The smallish ones like that tend to wear out like PRONTO on a street car.... Just remember that the outer portion of that joint is "smashed" around the inner portion and that metal is not exactly heavy duty. That and the teflon (or whatever) lining of the joint will wear out quite quickly as well. I would try to position the joint itself so that when you tighten it up the heim is centered and not all cocked to one side like that. There are rubber dampeners that you can install with the spacers that will keep it centered and quieter. I have seen people use zip-ties for that function as well.

Not sure if any of that will help your exact rattle problem or not, but those are things to keep in mind when running heim joints.

Hey thanks guys. Looks like I will be switching it around tomm. I will also try to keep that joint centered. It is really hard to adjust these thnings on the car without going to far or making that joint out of allignment. i would hope that this peice isn't worn out yet since it only has a soft 2,500 miles on it. Maybe less.

Did you just buy the end or a whole new unit?

Does this affect adjustable panhards with poly on both ends?

Just a new end. Email Spohn, I don't think he lists them on his website.

which part? the jam nuts. YES even more so on poly/poly, when the poly binds, it can actualy start to back the jam nut off.

which way it is mounted, has no effect, as you have the same bushing on both sides.

Well I turned it around this morning and it seemed to work. I also made sure that joint was as centered as possible and not cocked to one side like it is in the pic. I gave the car a good shake and it appears to be gone. Thanks for all your help guys. I would have drove it to make sure but the motor is all apart for the cam swap.

Sorry, I meant is the rattling an issue with poly/poly adjustable panhards. But I guess if it backs off the jam nut, that would cause rattling eventually.

Ever since these adjustable parts came out, my biggest concern has been longevity. Should there be a better design in the way the adjustments are locked in place? I drive my car every day through rough NJ roads, which I'm sure would just end up jarring the adjustment out of wack on my panhard and LCAs (once I get them).

as long as the jam nut is tight you will be fine. the panhards shouldn't back off, but if you put the poly into bind, it can work its way loose after a while. i would put some locktite on the lca's jam nuts.
