Front diff axle wrap? (1 Viewer)

[FJ73]

Has any one else had this problem? Im running an fj73 cruiser soa with a shackle reversal long leafs and shackles. Getting unreal flex with that heaps of axle wrap. Im thinking a ladder bar may be the way to but there is very little room and its going to have to be very short so i think it will bind up and limit travel.

Any suggestions?

Thanks

I think Andrew Farmer talked about a front traction bar a few years ago, can't remember if he made one or just talked about putting one on. Not a common issue though. Check out his ROTW from a while back.

Theres a few threads out there about the right and wrong way to build an anti-wrap bar. The bar that seems to work the best uses a shackle on the end attached to the frame, and a high and mid mount vertically on the axle. This allows the springs to still do what theyre supposed to, but wont allow the twist youre experiencing. I built one for the rear and it works awesome, I would thing the same principles would apply on the front, but may be harder to figure out where to put it. Good luck!

I have an anti-wrap bar on the front of my 60. I am not sure why other people are not having problems with axle wrap on the front but they do on the rear. I am currently building one for the rear axle. I have an add-a-leaf in the rear springs which helps to reduce the axle wrap but it still needs a bar. I like the anti-wrap bar to help protect my drive shaft as well.

Here is a link the the front anti-wrap bar I built.

Its not usually a problem becuase there isn't the weight on the front end like the rear in a hill climb. The front axles don't tend to hop as much as the rear can either.

are the clamps that hold the leafs on your springs clamped tight?

no there not so i get the most out of the travel. thanks PPfJ60 need seen or heard of onr on a front diff befor i already have one on the rear so will now make one for the front.

Huh?

The spring clamps are not tight allowing the springs spread.....! Getting loads more down travel. So yes i do realise this is a big factor in whats making the axle wrap just intersted if this is a problem for anyone else and how fixed? Im thing that the ladder bar is the better way to go. There is just very little room to fit it. Im also conserned that its going to be very short causing binding.

What kind of springs are those? Looks like lift Springs. that could be part of the issue, and i think it was part of the issue in PPFJ60's rig.

I would clamp those springs back together, or better yet get some stock flat spring!

the flex you are gaining is not worth the issues its causing. I think a wrap bar is just a band aid in this instance.. most soa guys dont have issues with front axle wrap!

toyota pichups came with front wrap bars from the factory.im pretty sure your gonna break something set up like that good luck

I ran a center limit strap on the front axle for a long time....it did not limit articulation, but only allowed the front axle to droop about 1" to 1-1/2" at the center...this kept the springs from fanning out during climbs when the front would unload and kept the wrap under control....also kept the front end from 'walking away' when it would get traction and the rear would not

I broke the crossbar in CA....wheeled in IN without it a few weeks later and noticed a LOT of wrap...on my list to re-install in the next week.

Mine was a custom 1" tube with a center bend, just enuf to clear the harmonic balancer, and welded to the frame in the same area as the front bumpstops

Brian .. did you have pics of your front strap .. ?

I'm in the process of a new front and rear track bar .. maybe the rear would keep the JJoint in the shakle side.

not presently.....will be rebuilding soon tho...

On flat ground the spings are dead flat they are stock rear springs..! The current setup works great if i can limit the axle wrap. If i clamp the springs back together i will lose lots of down travel if i can find awawy around that i be happier. But even if i do clamp them up it will still only be relying on pulling up on the last clamp pulling again on the top main spring.

I really doubt that, And tons of flex is way WAY way overrated.

 

[woody]

you won't lose lots....mine flexes plenty with the wraps clamped tight...

 

[PPFJ60]

I have stock (flat) springs in the front and an add-a-leaf in the rear. I think the add-a-leaf does not flex as much as the stock springs which limits the axle travel. The stiffer spring does help with the axle wrap. If I were to remove the add-a-leaf and not add the rear anti-wrap bar I would end up installing another ring and pinion set $$. I am about half way through building the rear anti-wrap bar now.

 

[HANCOCK]

There would be close to 300 mm from the last clamp to the do I need one closer to end of the spring? If so there is no point to mount it so what's the best way? I still think its a lot of force on the end of the spring I can only see a ladder bar if done the right way reducing that load its done wonders for the rear and its the same principle.

They just don't see it occuring, but it's there, and it's happening. When you look for it happening, you'll see it. Everyone wants to point the finger at the rear axle... try pulling into FWD, head up a hill, and see how much it hops. It's there. PPFJ60 & Woody's are proof even if you don't believe me.
