Passenger side leaning 1" lower than Driver side

Please help! My 1992 Formula is leaning and I do not know how to fix it. It has Eibach 2" lowering springs and they were already on there when I bought the car back in January. I have put on new shocks and a UMI double adjustible Panhard bar and it is still 1" lower on the passenger side. I thought that maybe the springs were the problem so today I removed both rear springs and switched them thinking that if one was bad then the other side would sag but no luck.

What could be the problem with my car?

Re: Passenger side leaning 1" lower than Driver side

Try the front springs? When installed they have to be "indexed" so that the car sits right. The driver's side is probably not indexed, causing it to be higher.

Or are you talking about how high up the wheel well lip is from the tire? On that, I don't know.

Re: Passenger side leaning 1" lower than Driver side

Ok I haven't tried the front springs yet. The weird thing is that both the front and rear of the car are off by exactly 1" front the driver side. I am measuring from the top of the tire to the wheel well.

I had a similar problem with my car a while back. The spring wasn't in the upper perch quite right so it lifted one side. Check your front springs and remeasure on a dead flat surface.

Ok I will try that tonight! If one of the front springs was off, would that affect the rear aswell?

Re: Passenger side leaning 1" lower than Driver side

meh, hard to tell. I would say yes. I think I noticed a 3/4" difference in the front and a 1/4" difference in the rear of my car. If you unbolt the front sway bar and lift the rear end (by the middle of its axle) you should see what the problem is right away. Ideally with the rear off the ground and the sway bar unloaded the front will settle according to the springs only.

Good Idea! I will try that. I'm hoping its just the springs or a bushing. I had another guy tell me it could be my LCA bushings.

Re: Passenger side leaning 1" lower than Driver side

It's true that if you lower the rear with urethane bushings in your LCA's that they will bind. Reason is the panhard bar sweeps the rear end towards the driver side as the rear compresses. I would think this would stay pretty left/right consistant though and not bind up only one side. Getting an adjustable panhard will fix this problem for its usable travel or you can shorten an existing bar by cutting and welding. If you have lowered your car significantly in the rear you should do that and get LCA relocator brackets.

Re: Passenger side leaning 1" lower than Driver side

I actually just put an adjustible panhand bar on last week and it is still leaning. What would the LCA relocator brackets do?

Re: Passenger side leaning 1" lower than Driver side

When you lower the car the LCA's form a bad angle cause they slope down. They should be fairly level. If they point down from the axle it also causes bad wheel hop since any traction will cause the axle to lift. LCA relocator brackets drop the axle mount point to help level this angle.

Ok I just went out and checked my LCA's and they are almost level. They slope UP just a little towards the rear axle.

What about ball joints? if they were bad could that cause my car to lean toward the bad ball joint? That is one of the only things I haven't thoroughly checked yet.

Re: Passenger side leaning 1" lower than Driver side

Ok I still can't figure out why my car is leaning to the passenger side. so I started thinking that maybe my frame was bent for some reason, so I took it to a frame shop today and they said that everything looks fine. So... What now?
I'm considering on putting stock springs in and see what happens. The eibach sportline springs that I have now were in the car when I bought it so it is the only thing that "I" haven't replaced. I did take the rear springs out and switch sides to see if that would do anything and it didn't. I havn't messed with the front springs yet.

Any Ideas?!?!

Re: Passenger side leaning 1" lower than Driver side

Ok so I took out my front springs today and figured out the problem. Just the driver side front spring was not seated right. I adjusted the spring and now my car is FINALLY not leaning! I can't belieave that one spring not sitting right would cause that much of a problem.

Re: Passenger side leaning 1" lower than Driver side

or losing a spring isolator from the rear...they're thick and significant. the fronts are mickey mouse rubber, but the rear is like 1" I think.

Re: Passenger side leaning 1" lower than Driver side

they may look to be 1" thick in the package but most of that is just to make a pocket for the end of the spring to sit in. I just recently installed these but I can't seem to remember what the measurement was. I know it was around a half inch, I'm thinking like 5/8".
