I removed my sway bars this A.M before an all day trip of full articulation.
Problem: When the front springs are fully compressed (either side) the spring bows to the inside and rubs against the frame. I'm not talking a little nick. The frame is really pinching the hell out of the lower "ring".
The springs are OME(HD).
I'd love to solve this problem because I just dug the amount of articulation I was getting.

Anon,
Are you suggesting or asking?
BW
I do not have cones on my rig. |

Cones won't work on the front unless you mount your shocks outside of the springs. Personally, I wouldn't reccommend cones up front and you won't get enough flex up there to need them anyway. The cones wouldn't prevent this anyway since the springs aren't moving at the top, it's the middle that is bowing out and there's enough room around the cone to allow this to continue.
I've had my front sways off for quite some time and have never had this problem, but I'm running RTE springs. Seems odd that that is happening. I just don't remember my springs being that close to the frame under compression. Very strange. |

I might try and rotate the spring 90 degrees so that the bottom ring is near the frame. That might keep the "next-up" ring from protruding towards the frame under compression.
Yeah. I thought it was very strange too. When I heard the springs getting bit by the frame I just KNEW the springs had snapped.
I wish I had one of those ramps where you can drive up and get the full articulation. I'd like to see it first hand.

A handy ditch, curb, etc. could make a ramp of sorts just to see the spring action. Doesn't have to be a specific ramp to test your need. |

Greg,
I inspected the springs again and have came to the conclusion that rotating the springs will not help. The position I wanted to move one spring to is the exact same position the other spring is in.
I can't figure this out. Due to the lack of response from this board, or lack of interest I seem to be "stuck".
The only thing I can think of is that MAYBE a lateral shift is causing the springs to rub. I have checked every bolt underneath. Everything is snug.
Can you think of anything that would cause a lateral shift during compression?

Could it be possible that you just got a bad spring? Maybe a faulty one?
Or would the sway bar somehow keep the lower part of the springs from traveling inward? And with them gone has nothing to hold them away from the frame?
I don't have the answer, sorry I'm just as confused as you are and just trying to help. |

Loosen the bolts to the spring perch and see if there is any play in the bolt holes. If there is move the plate as far as possible to the outside and retighten.

Greg & John,
I crawled back under her this A.M. I can't find anything loose. I think the springs are OK. Both left and right springs are rubbing. I wouldn't think I'd have two bad springs. The front left is rubbing more than the right. Maybe John D is right about the spring perch. I'll give that a try next weekend. The parents are flying in tomorrow so I'll have to lay the tools down for a few days.

Am I understanding correctly that this is happening when the spring is compressed? It sounds like most everyone's advice is relating to the spring during extension. Just wanted to clarify and also make sure if I'm misunderstanding maybe others are.
I find it hard to believe that a HD spring could compress enough on the front of a disco to bend very far inward. I would probably be looking for an alternate reason like the spring perches or the spring coming off it's seat during extension, and then pinching the frame during compression and reseating. I don't think too many people have a problem with this on the front, but I could be mistaken.
How long are your front shocks? Any problems with brake line stretching? On my DII I would have to flex pretty far to unseat my springs. My brake lines would snap before I had major problems, but I guess it could happen. Greg D mentioned cones are not necessary on the front, but if you are unseating your spring, you may need to investigate cones or retainers.
Just my uneducated guess. |

maybe your panhard bar bushings are bad that would allow some side to side shift under full tuck. |

Greg P,
The "scraping" is occuring during full compression. I still have stock shocks on. No problem with the brake lines.
Muskyman,
I do not know exactly what the "panhard bar" is. I have inspected the lateral linkage from the frame to the axel. I don't know the technical term for the linkage/arms. Could you describe the "panhard bar"?
I wish I had a small camera to mount underneath.

BW, the panhard bar is the lateral link from D/S of vehicle to P/S of axle. These busings are hard to check. Have someone start the vehicle and saw the wheel from left to right while you look at the mounts. If everything is tight and not worn, you should not have any lateral movement from the bar. I'm not sure that even if it were worn that it would allow enough movement for the springs to rub the chassis. I'm really scratching my head on this one. |

I'd be curious to see what would happen if you removed one end of the panhard rod. Could it be defective? |
