Rear Axle Suspension Question

[Onelfastlride]

Alignment shows my rear axle has -0.2 degree camber on the driver side and +0.2 degree camber on the passenger side. I think this basically says the entire axle is tilted slightly toward the passenger side (driver side higher and passenger side lower).

Anyone have any ideas why?

The car is lowered with Steeda Sport Springs, Whiteline Upper, Lowers, Relocation brackets, Panard Bar.

Yesterday I dropped the axle. As I lowered it I noticed the axle remained tilted slightly. I disconnected the shocks and sway bar and it remained slighted tilted, even with the springs out of the picture. So I disconnected the panard bar and bingo, the axle leveled out and shifted slightly to the driver side.

So I think it's the panard bar pulling at an angle toward the passenger side. Is this normal?

The only other thing is the lower control arms? I don't know why it shifted slightly to the driver side after disconnecting the panard bar.

Panhard is not adjusted correctly

That is probably due to tread and/or tire pressure differences between the left and right rear tires.
The Panhard bar will not affect the camber of the rear tires, actually nothing on the suspension will really affect camber since we have a solid axle.

If it's not adjustable you need to spend a little cash to make it right

Yeah, I’ve adjusted the Panard Bar a few times now. Additionally the alignment shop centered the axle also.

Are the lowers adjustable

If you want it spot on have them align it with you in it, just with you sitting in the car will change the alignment

Also if the springs are clocked you can get a little out of thoes

Yes the lowers are adjustable.

You might need to adjust them slightly one side might be a little longer than the other shoving the axle over

Yeah, I’ll triple check them and see.

Perhaps with the Panard Bar off. They maybe off less then an 1/8” from my last checks with the car up on ramps in the rear and the front raised up level.

I had that happen on a sn95 car I had once

Measure the rear of the front wheel lip and the front of the rear wheel lip when the steering wheel is pointed strate and see what you get, the car will change alignment when you are in it also, I'm 265lbs so it changes alot

Yeah it’s minor but bothers me. I need to check but I wonder if the passenger side lca is a touch longer. This is based on the fact the axle shifted slightly to the driver side when the Panard Bar was disconnected. Like it was pulled to the driver side by a shorted lca.

There you go , I think you might be on to something. If the alignment shop is cool have them align it with you in the car. Btw doughnuts make all repair shops very cool. I know this because I have worked at one for 20 years

I’ll check the lower lcas but I’m not sure that’s it. Because I believe the alignment shop thrust angle measurements were good, ie 0. The angle of the rear axle compared to the front.

You certain the floor is perfectly level where the measurements took place?

You may want to confirm that your axles are straight. Ask me how I know...
