Sounds like the best thing to do is change the springs & put the 32's on.. Thanks heaps guys!!.. Sounds awesome John, Keep me informed. I think i might have to save some extra pennies & re-do the whole system. Will have to do the snorkel first as it's comin in to flood season.
Cheers Guys
Tony

No worries, glad to help, i am hoping to get mine done soon, but the list is long and i have something on every weekend this month, 2 are 4wding, have to get my new front bar made and get the winch fitted and wired for a run at the start of november, plus re-do half my wiring so i don't blow fuses as much, and make 2 ground anchors!!! so much to do, not enough time to do it!!!

I make a Hilux/MU extended shackle with greasable pins for $130/pr. I use brand new greasable pins and custom make the side plates from 8mm plate which is somewhere in the vicinity of 150% stronger than the standard 5mm plates that are used.
Oh, John - why are your springs so expensive? Are you buying the torsion bars as well?

Full military wraps front and rear, nylon inserts, I'm still waiting for a reply as they are really rodeo ones and 5+1 leafs will be too much for me as i only have 4+! at the moment and i don't want to go any heavyer. If they can't do it then i might have a look at yours again, but are they 5+1 too??

If they turn out to be to heavy you can always remove a leaf. You might be suprised though as if these springs are like mine each leaf is quite a bit thiner than your originals. Add the nylon (or teflon?) inserts and they might give a perfectly ok ride and still articulaty ok. What brand are you useing Mine are Lovels and were made in Aus but still a lot cheaper but only have partial military wrap and no inserts

You've seen the photos of mine flexing up really well, and they are 5+1's. Until I drive it I won't know, but they actually seem nice and soft. And they are $300 for a pair. You do have to buy a urethane bush kit for the front spring eyes, which is an extra $25 or something like that, but otherwise the bolted straight in (oh, they don't have the handbrake cable brakets that genuine packs have... but hey, thats what zip ties are for ) Steve

Hey guys, the springs i'm looking at are EFS ones from aussy, they have the full wrap on one end and a half wrap on the other, with taapered leafs (whatever that means). I have bent my old sprinds quite bad so i need them with the wraps.
Hey steve, If you could put up a photo of your springs that would be really great. Are your ones the maxitrac ones, as i can buy them from repco for about $100 less than your offer. I dont want to be a prick, but that way i don't have to pay freight or that,

Mate i am the first to admit that i am NO EXPERT but you should be cautious if you are thinking of 2" susension lift as well as extented shackels. Some of us in OZ, not me, but others have tried to combine the 2 options and have found that the tail shaft angle to great resulting in a constant grinding noise. My Mu suspension lift was closer to 2.5" and myself and jimmu both have a slight grind sound only when the tail shaft has is under power or tension engine braking,...the point when you take the power/accelerator off and when the car rolls by itself, if that make s sense).
Just thought to warn you first that anything/most suspension lifts over 2-3" will/might end up with this problem.
Cheers Pissy

Like Chris pointed out. The vibration is a pain the arse!
I have tracked down some tailshaft spacers that should solve the issue, I need to duck over the slacks creek and pick one up and test it out.

Hey John - if I could buy something at some crazy-assed staff-discount price, or pay full retail, then I know which option I'd be taking Don't sweat it. Also, you might want to consider a driveshaft similar to the one I made using a Hilux double-cardan to avoid that grinding - and when you make the new spring perches you can then point the pinion straight up the driveshaft to virtually totally eliminate any driveline vibration. The only thing I'm not totally sure about is the long-term strength of the Hilux double cardan joint... time will tell... if it survives my lead foot, my 3.1TD and my 36" Simexes then it should survive in your beasty Steve.

Jimmu - Tailshaft spacers to eliminate vibration? Won't they just effectively make the driveshaft shorter, therefor the angles (ever so slightly) steeper, therefor the vibration (once again, ever so slightly) worse?

Hi Steve,
Yes. In a way it will. While it will add to the length of the shaft the current driveshaft will be more compressed on the expansion joint so it will be shorter.
Which I am told should eliminate the grinding noise problem which is aparently fairly common after that sort of lift on many vehicles.
I am hoping the unit for a hilux will fit the tailshaft off the MU.
Aparently the problem is not so much the angle of the tailshaft itself but the fact that after a lift distance between the two ends of the shaft increase and the expansion joint is then operating outside where it should be.
But there is only one way to tell for sure and that is to try it!
Either that or get a new tailshaft made up.
Jimmy.

Thanks Himuzulux, my mate at repco gives me real good deals!!!
I was thinking about pointing the diff up-wards a bit, this wouldn't cause any bad affects would it?? i can see what you have done to yours there, but i really don't want to have to do something like that if i can avoid it. I was going to ask this question in my thread, so any opinions welcome here!!

Its VERY important that when you use a standard uj to uj driveshaft you keep the angle on both ends the same... don't rotate the diff unless its to do that.
UJ's run in an eliptical arc, not a circular one so they need to be in sync to stop vibration... but if they are on different angles then the eliptical arc is different - which introduces vibration...
Hope that makes sense.
The double cardan runs in a true circle due to its design of two UJ's, so you have the UJ at the other end running perfectly straight (the only point where a UJ runs in a circular pattern) and again, no vibration.
Steve

What is military wrap?

Post by geeves on Nov 2, 2005 14:13:20 GMT 11
OEM springs generaly only have an eye in one leaf and all the other springs rest on this. This type of eye is a weak point and if it breaks renders the vehical undriveable. In military wrap a second spring also forms at least part of an eye so if the spring fails the vehical can still be driven to get home. Breaking springs is rare which is why the manufacturers dont bother but most after market springs are made with military wrap

Try looking up efs on trademe, they are who i'm buying my new springs though, or just have a look on the net, like gevees said, they are pretty common. Both myself and a freind of mine bent our springs just behind the front eyes, which reduces the springs lift quite bad, my friend got military wraps and he bent his under the diff, not just behind the eyes!!
Stay tuned as my new springs have been ordered and i will have them in a couple of weeks, i have a thread going in suspension about remodeling the rear suspension.
Hey steve, so you are saying that i can't tweek the diff head up a little, like a couple of degrees when i put the new spring plates on?? as i am running the standard mu drive shaft??, you kinda lost me a little.
