This info aint even really for my good but id like to know bout it. My buddy who had the samurai traded for a 84 sas 7in lift well i seen him take off earlier today and his axle went from normal to pointing up ( axle wrap ) i know you put blocks in there to tilt the dif up when lifting a truck hight like that but how do you fist the axle twisting? I know theres a way im sure theres a thread i just cant find one.

anyways if you could give me tips to relay to my buddy that would be great then ill know how to fix that prob if i ever have that prob. lol ( got pics on my profile thingy of my buds 84 if you wanna see it )

 

traction bar

 

+1 to the traction bar.

 

hmmmm but that wouldnt help at all for flex and would get in the way for wheeling right???? lol its somewhat normal for the axle to twist a lil right? see he has a 7in lift on 35s am sure its geared it has too but im not sure maybe if he geared down more? my dad has a 89 on 35x14.5 with a built engine and he dont twist like that ... i was like HOLY hes going to break the ujoint lol or drive shaft lol

 

Is he using lift blocks as part of his lift ?, they can cause axle wrap real bad, thats why its not a good idea to use them. I have 16'' of lift on my 86 4Runner and i don`t get any axle wrap at all, so maybe his lift isn`t set up right ?.

 

The blocks cause a lot of the axle wrap because it increases leverage on the springs. A trac bar does not increase or reduce flex. It just keeps the axle from twisting. It also does not get in the way while wheeling, the differential hangs down farther than a trac bar.

 

yes actually we figured that out last night i guess he didnt notice them before i was thinkin the same thing that the blocks would cause wrap but he said he didnt have any so i looked lol and i was like UM YEAH YOU DO DUDE! lol but eventually he will get lift springs not just blocks. lol ME i wanna get a 6in spring lift for whatever 4x4 toyota i get. I am thinking marlin crawler idk tho whoever is a good good brand high quality and is in a decent price range. i can do all the work.... OH AND FOR THOSE OF YOU WHO KNEW BOUT IT. I GOT MY BUDDIES 85 TRANNY IN AND DONE AND ITS RUNNING NOW.

 

The solution is link it.

Leaf springs are always prone to axle wrap. There are things you can do to minimize it, but always at the expense of flex or ride comfort.

Leaves are cheap and easy, but as with all things, there is a price to pay for the cheap/simple solution.

 

yup but not everyone has the money to link it, lol he will prob end up rebuilding the rear end meaning new springs, new shocks, prob new axles and gears / locker lol knowing him he will redo tho whole truck in time.

 

anyone know where i can get a good traction bar. i dont have alot of money to spend, but i have to get rid of this annoying axle twist. also, what are some other benefits/problems with traction bars.

 

I think the Budbuilt is going to be the easiest way unless you have access to a welder. Its all bolt on. But there are other universal kits that will requite welding to the frame and the axle (google will help you find them) . Benefits are it practically eliminates axle wrap and semi protect your driveshaft, when set up correctly there are no cons.

Edit: and congrats on bumping an old thread rather than starting a new one. Way to keep an old thread alive!

 

Another option is to add an anti-wrap leaf to the top of the spring pack:

Basically a half leaf that is held under the spring plate and arched so as to pull up on the front of the spring pack to resist the axle itself twisting:


Does not eliminate axle wrap but goes a long way to controlling it, especially at low speed like rock crawling. And does not affect the ride or suspension travel or flex. I run them front and rear on my '85.
