can new springs settle at different rates ??

[5inchgq]

I ve just put a 3 " lift under my gq lwb (springs, shocks, castor correction, panhards etc ) and have been a bit worried about a 25mm sag on the passengers side, rears heaps worse than the front. Took it back to the manufacturer of the springs and questioned them about it they said we'll have a look , they tell me they took the springs out measured em its all good but your chassis is bent , so i took it to a chassis guy with caraligner etc he says nah mate it s your springs !! I ve just gotten back from a 300 k round trip all highway with all seats filled and it seems to have come good . Has anyone had springs settle differently left to right ? Would love to know cause it s still a daily driver and the mrs is screamin at me to put it back the way it was !! Any and all advice would be greatly appreciated .

Cheers

there are left and right springs to counter differnt weight... theres also front and rear springs. They could be the wrong way around.

I'd go to another suspension place and ask them for advice...

I fitted the whole lot myself and all the springs are in the correct corners etc . I went back to the place where i got the springs cos they made em !!!

Happened to me with the 2 OME suspensions I have bought. Fit trimpackers on one corner. Should solve it.

My GQ is exactly the same, from the factory and after a lift kit. I've measured many reference points on both sides and can't work out why it sags on the passenger front side. Looks shit house too. Any ideas?

have you swapped springs left to right and tried again?

We did that at installation. Swapped the R -> L on both front and rear incase the stickers were on the wrong springs. No difference.

take them back then

There is a possibility that it can happen. The only way to know yourself is to take them out and check their free length. In reality there shouldn't be much of a difference between the pair of springs. If they are the same or close enough to being the same might be worth asking the spring company to load check them for their spring rate. They should have the facilities to do this.

thats next on the list elmo will keep you guys posted !!

One tip for all to remember is to mesure the heights before fitiing new springs. That way you know for sure exactly how far each corner went up and weather it ia a spring problem or just the chassis/body sitting uneven..

Also its not overly an issue on patrols that i've seen but it is always a good idea to release all rubber suspension bushes (leading/trailing arms, panhards etc) and retighten "at ride height". Failure to do so can put stress on the bushes and also cause the vehicle to sit uneven..

Just remember the height of a spring depends not only on free height but also coil thickness, wire length , material used etc

[Suspension Stuff]

All the drivers side coils are usually about 10-20mm different in free height otherwise the driver and battery sags the drivers side down. The spring rates are the same or within a fraction because everything else about the coils is the same. It is likely that you may sit up a bit on the drivers side until the coils settle. (As you have suggested)

If you swap over the coils from left to right both at the same time then I can't see how it could be the coils unless you then sagged on the drivers side after you swapped them.

Every vehicle has different weights over different areas of the vehicle so it isn't going to be an exact match but it should be very close for most people. I wouldn't think it would take too much to twist a chassis, they twist a lot when you flex it up. Maybe after you give it a hard time it has corrected itself. This is assuming that you did everything perfect when you swapped them over.

Life tells me that there are lots of things that can go wrong or done differently, like the coils not seating the same or in a different place when they were swapped over.

You may have had the shocks off on one side when you swapped them over. Shocks can raise your vehicle if they are the type that push out such as Procomps etc.

Shocks could be a bit stuffed on one side.

Panhard rods might have been pulling down on one side.

Maybe the castor correction bushes are twisted because of bent arms.

I'm no mechanic there is probably a lot more things that can go wrong.

If you get a 3" lift it is usually a 3" lift from a standard vehicle not your sagged out coils. Nissan brings out a different coil just about everytime they bring out a new model so standard heights do vary from the Nissan factory. However aftermarket coils have their normal duty, heavy duty, extra heavy duty coils and that's it and whoever you bought them off selected the best coils to do the job given the accessories you have or told him you have or have planned.

Anyway it is good it has worked out for you however it can be stressful not knowing what is going on.

Sorry mate I can't help you with the MRS that is a whole other problem and logic may not work for you.
