fj40 coil spring removal

Post by **rx7fj40** » Sun Dec 24, 2006 10:02 pm

i just bought a shorty 40 82mdl it has a very stiff ride and it has coil springs on top of the leaf springs. is this normal for this model?
can i just pull the coil springs out to give it a softer ride?

also i need to get a roll bar for it is there anywhere to buy these of the shelf?

thanks for any help

How many leaves does it have? Outback suspension does mods where they add coils to leaf sprung vehicles but they usually take out most of the leaves. I had a Hilux with this done front and rear and it was great. It only had two leaves in the front and three or four in the back. When you disconnected the leaves from the eye mount they actually sprung down so that the vehicle was riding on the coils only until a mega compression when the leaves kicked in for assistance. The leaves were basically only there to locate the axles. Perhaps yours was done by someone with no idea though....

thanks for the reply, ill check on how many leafs there are, but it is very bouncy.
is there any way to tell if its a proper Outback suspension job?
thanks

If it's very bouncy, it means you most likely need new shockies.

It may have a sticker if it was done by Outback but the easiest way to tell would be that it is a great improvement over standard. It sounds crap so it is probably a back yard job. If the coil looks like it is well mounted then you could experiment with removing some leaves or just take out the coil.

Andy - he originally said that the ride was "stiff", and you are right "bouncy" would be shocks.

when i bought my shorty it had the coils as well as a full set of leaves. the only flex was in the tyre sidewall. the coils and mounts on the diffs came off with an angle grinder.

im about to take the coils out as i think they might stress the chassis rail too much where its not ment to.

i have ironman shocks, does anyone know if these are a really hard type of shock.
As that may explain why the front is really hard considering the front doesnt have coils aswell.

are there different stiffness of ironman shocks? and how would i tell what type they are?

thanks

i think its more likely the front is stiff because of poor spring design.
things like bad shackle angle, too many leaves, leaves clamped together too tightly, leaves not tapered or leaves too thick can all make for poor flex.

ok i got the coil springs out of the back a couple of days ago and all seems well.
the ride in the rear has softened alot and the over all ride seems better.

the front is still hard, im going to try some softer shockers in the front to try to loosen it up.

thanks clint

Std 40 has no coils, take them out and see how it rides then if its still bad you can take a few leaves out. 40's expecially the swb are bouncie.

outback susp are around the corner from me, most OBsusp jobs have been fitted with KONI shocks, if it was done buy a backyarder
i'd check the chassis for cracks around the coil locaters as to harder coil puts to much weight in one spot causing stress cracks. the right coil and leaf set up evens the weight over 6 points of the chassis per end.

hey im in croydon aswell, no it has ironman leaf springs that are load carrying ones and ironman shocks aswell.

im going to get some new shockers for the front as the back seems much better now.

thanks clint

I ran the same load carrying springs for a while mate they are rough.
You can get away with taking a couple out of the pack which will improve the ride. It's a way of life with a 40!

ok im might have another problem, are my shackles ment to be on a 45deg angle?

as this is what my rears look like

Post by **rx7fj40** » Tue Jan 23, 2007 11:12 pm

this is the fronts

Post by **MY45** » Wed Jan 24, 2007 4:03 am

No, thats about the angle that they are std. If you pull some leaves out of the packs it should improve the angle of the shackels a bit but you will loose some ride height. That said you will also improve the atriculation (if your shocks allow it) and ride. Just know that taking out too many my cause some axle wrap. The reason those are almost upright is because they look like there 2"ish extended
