FJ 62 SOA begins!

Yes, it is overkill for just an anti-wrap bar. I will eventually build another crossmember in front of the transmission and put a skid plate between them. i would rather overbuild than have to worry about it in the future



i cut my exhaust off at the end of the cats. I will get a shop to redo it later.

I was wondering how you got around that, as the exhaust was missing in your pic.
I got a price from a muffler shop to re route the whole system using some bigger dia. pipe...425.00. Not too bad I dont think. Just cant afford it now, so Ill work around it for the time being!

Be careful with larger diameter exhaust...it will alter your backpressure with a more than likely reduction in low end torque/response...unless you are installing a SC to push more air through the system .

Also, i am gonna run the single bar instead of the ladder bar.

single bar doesnt work. I does not stop axle wrap. there was a good thread a while ago in 40 series section all about it.

 

[SCJO06]

So what would be the best option as far as to eliminate axle wrap?

Straight bars are weaker unless you use some extreeem stock.

Think about how much weight a truss roof can support with just 2x4's compared to a beam. The ladder bar is a type of truss, it gives the most strength for the least weight.

Actually you can build an anti wrap bar with a single bar. It just takes an impracticaly large hunk of metal to do it.

The ladder bar Chicago sketched is a good example of how most people do it. It is a tried and true design.

There's also a good thread in the "hard core" section about 2 pages back...
A lot of discussion on the trac bar issues.

a 2x3 piece of tubing that has 2 conection points at the axle end should be strong enough to keep your rear axle safe.

It would be very similar to a radius arm suspension (think FJ80)

The key to a single arm bar is the multiple axle end points..

The only set up I've seen like that bent the first trip out.

JK customs makes one for sale.

I have seen one that failed as well. 2x2 tubing. It all depends on how strong the material is

What wall thickness on that 2x2? .187 or .250?

 

[Mace]

failure was probably .187 .250 is fairly strong stuff..

 

[YODA 88 62]

I already have a piece of 1/4in thick 2x2in tubing. it will connect like the jk customs on the axle.

While I haven't done a SOA on a 60 series, I've done a few SOA's. My questions are why can't you just build a better spring pack? I was able to build one that rode great, supported the weight and did not have any spring wrap on my Jeep. Also my 4runner did not have a anti-wrap bar and again I didn't have any problems with spring wrap. Both were geared low and wheeled all over the west.

Keith, you have the AAL's, so are you sure that it's going to be a big problem? I know what can happen when they do wrap, but isn't there a different way?

[Cruiserdrew]

This is a good question since Pismo Jim drove his SOA for years with no wrap bar. I have beefed up my springs with another long leaf from another spring pack, but I'm still going to build an anti wrap bar. The guys I've seen with a broken pinion are hating life.

this the one I run I run on my 40, works well. broke three pinions before adding it. now I can pull the front left tire off the ground on the street with out worring about the rear end.

 

[SCJO06]

thats a huge frickin track bar!!!

That looks pretty good there BOSS!
I am really diggin the way that you mounted the shackle to the x member too!
The way I was thinking, was that it was gonna have to go on the TOP of the x member, which would move the bar UP, but this is a good alternative and kind of splits the difference!

How much arc does that shackle endure? Its doesnt rotate up to 180* does it?

NICE JOB!

Hey Jack!
My thinking on this is... Id rather put forth the extra effort now, rather than be sorry later on the trail in the middle of no where later.
Im sure the AAL's would help the situation, but im really not willing to bet on it. Rusty TLC has a pretty strong opinion on this as well.
He is of the camp that trac bars are REQUIRED for an SOA and the difference is night and day!
Im trying to do things, simple and trying to make things bullet proof as best I can to avoid failure on the trail...Now, with that being said, there are limits as to what I can spend to achieve this (Longfields...just cant afford it right now!) the trac bar is something that I can make and not spend a bunch of coin on!

You prob did have axle wrap but where not aware of it. Most people find out they have axle wrap after its too late..couple good hops, skinny pedal, snaped pinion.

A good way to test it is to let some one drive your rig backwards and mash on the brakes if your rear springs turn into S's you have axle wrap.

Yulp mace you are very much correct. I have seen a few bars like that, Wag has a very nice one...I was just thinking of a numerous amount of axle wrap bars out there that have one mounting point and one bar. A fellow cruiserhead this GSMTR broke 3 pinions because of it.



As for why Pismo Jim did not break one. Although I have never met him or been on the trail with him. He might not have been that hard on the skinny pedal. Also the Fine spline pinions are a great deal stronger than the course spline you find in most 40series. I think by the time you built a spring pack in the rear that stoped axle wrap you would have almost nil flex and a very harsh ride.

Well theres my 2cents...

wrong you are surfer boy!

as long as you have three mounting points. 2 at the axle fixed and one at the front of the bar that allows for movement.
the single bar IMO is a better design.
