Outer Limits 4x4 Board

Was under my GQ checking the Transfer Case oil, and having a perv at my new OME Suspension, and noticed that the rear springs are "bunched" differently

You can see in the photos that the left spring has the coils bunched at the top, while on the right, the coils are bunched at the bottom.....is this OK?






Is there such a thing as an upside down spring?

The front ones both seem to be bunched at the top....

I think one is in the wrong way

normally different distance between coils means a different compression rate, i'd agree that one is upside down and you'll find it will handle quite differentlt at extreme compression, etc I found this out on an old gemini where i made that sam mistake...... and yes they should go in a specific way...... not sure which though

so there is a right way????

Upside down
take it back & make em fix it.
It doesn't take long to do it yourself, but y bother they stuffed up

somewone has to ask, was it put in the correct way?

im no expert by any stretch of the imagination but i wouldnt have thought new springs should bunch to that degree in the first place, im obviously wrong but just a thought,

my reply will be of absultely no help but im thinking re slight difference in spring lenth for divers side vs passenger and weights and this relating to spring loading,

I did think about this, but wouldnt they have done the same on the front?

OME state which way up the progressive rate spring goes, meaning that there is a right and a wrong way.I can not remember which is which but take it back and have it fixed.

you would have thought so but unsure

the coils have a top and a bottom.. they have a differnt seating on the top to the bottom on the mounting plates.. the top of the coils is flat, and the bottoms has a pig tail that locates in a notched out section on the bottom mounting plate..it actually not an easy mistake to make.. the coils will be visably not seated if fitted upside down.

the top pic is on the right way, but the tail isnt sitting up to the notch. in the bottom pic the notch isnt visible so hard to say, but the coil looks to be upside down

Hmmm, just had a look but cant really tell......wonder if my newly aquired vibration is due to the potentially upside down coil????

how much lift is ur new suspension? if its 50mm or more, the vibes will be ur tailshaft angles due to the lift.. welcome to the 'gq vibes after lift club'.

No your vib is more likely to have some thing to do with G/B flange to Pinion flange misalignment from your lift.
The usual fix is a pair or four gearbox packers,depending on whether you are a SWB or LWB and the inches of lift.

funny cos its true,

you now own a shake rattle and roll patrol....not being a smart arse just feeling your pain...

wizard drop brackets on mine helped but catch on everything...

cheers mate
Bingham

who put them in because it doesnt give them much hope if they cant even put new springs in! or maybe a few beers were had during fitting!

its a 2 inch lift on a Shorty....

Its going back this week for the mesaurements to be done after the 500km, may also be getting the gear box packers put in after they have a look.

Could the spring possibly be causing the vibration though???

id say spring not causing vibration as the weight of the vehical would be enough to hold it firm even if it wasnt located properly...as to your vibes, are they constant, or do they come at a certain speed or rev? at 50mm u will find that its the pinnion -uni misalignment as mentioned already.

Its at about 40 -50 kmhr, vibrating in the back end, seems worse under load?? Not rev related...
how would I go about fixing the pinion - uni misalignment?

also...wizard drop down brackets will only help ur front end shimmy dramas after a more dramatic lift then 50mm.. caused by not enough castor correction after lifting front end suspension. get ur spring checked that its in the right way, check to see if vibes are still happening, then try a single 6mm packer in the x-member..should be adequate to sort out 50mm lift vibes..if not, id give the guru cheezy a buzz and have a chat with him..

yeah thats definately due to the new angles of the shaft..like i said, at 50mm lift id go the 6 mm x-member packers first. when i got my lift, 5 inchs, i had about 30mm of packing to rid my vibes..but this amount of packing is no good. 6mm will be fine for u..

on bigger lifts u have to get ur pinnion angle back down to where it was standard..by using longer lower trailing arms. most guys go the way of shorter upper's to spin the pinnion up higher but this is not the way. like i said before, speak with the guru's. cheezy does a bizzillion lifts on gq shorty's and will tell u what to do. wheter u buy his gear or not. but he sells the right gear and at cheep cheep prices for stuff of top quality. call him.

What is that swaybar doing still installed?

ey??

This is a daily driver too.....

Personally I'd still ditch it it makes cornering more fun

agreed. Majority of patrol users dump their swaybars after lifting / touchin the suspension.

TOM

hard to say if id dump my swaybars on a 2 inch lift.. dont think it would restrict amount of travel, but will make body roll a bit more pronounced. if ur lift is comprised of heavier than standard springs u should be ok in the body roll depatment while the shocks are still new and working good..but after a work out when they start to fade the body roll will be worse. if u had something like the big bore ralphs then id say ditch the sway bars. they wont fade or soften up and are adjustable so will take care of body roll issues under all ur circumstances if u adjust them up properly...

after all that being said, id dumped my sway bars after my lift, but i went up 5inches
