Hey Guys,
My 89 f150 has a 4" suspension lift and 33's on it. The back end if u giver hell at a dead stop the back tires hop so bad. It did it before the lift and tires got put on and now it does it more. It has new leaf springs, and only put 54 miles on since the lift was put on. I just want to no if this is normal or if something is broke that i'm missing. Can anyone help me

 

you need some ladder bars or something compareable to stop the axle from rotating up and turning the springs into an S shape. If you continue to let it wheel hop, you will break parts for sure.

 

Thats it? if thats all i can put ladders on. I wasn't sure if that would've helped thanks

 

there are a few different types of traction devices, it just depends how fancy you want to get. I have found my ladder bars do hurt the articulation in the rear, I have also built a single ladder bar, mounted it near the center of the axle with bushings and built a crossmember in the frame to hang a shackle to the ladder bar. This way it lets the axle articulate normally, but it also takes more fab work than simply bolting on two storebought ladder bars.

 

K good to no

 

Did you do the lift with blocks? if so thats whats causing your axle wrap

 

Yea i DID, BUT LIKE i SAID BEFORE IT DID THIS BEFORE i LIFTED IT

 

Calm down kid, no need to be an *******.

What tires are on it?

 

dont need to freak out here, notice how you said it got WORSE after the lift, well the lift block are ADDING to the axle wrap, no need to bite someones head off here. Heck my truck will hop the back end if i try and do a burnout at a stop. I take it as part of havin a truck, plus im not a big fan of burning my tires off, as tires are usually expensive, i dont know about you, but i know that i have to pay for all of my own things. including tires, Why would you want to do a burnout with 35" tires? Doesnt make much since to me, bigger tires USUALLY cost more money. Go out in the mud and sling some mud with those 35's and be happy that you can, dont worry about roasting em off.

But if you must, i do belive a ladder bar would be of benifet to you. As has previously been stated, dont know if it will be enough to also counter the effect from the lift blocks, but it could help.

x2 on the breaking of things if you continue to try and do burnouts, hopping the rear ends is a sure fire way to make something break, atleast from what ive seen!

 

Another thing to check is your tranny/transfer case mount. With an older truck, like yours that had seen some abuse (maybe not by you, then again, burnouts are abuse) the tranny mount will eventually wear out and break. Especially since you had the wheel hop before adding the lift. If you keep letting it ride, you will eventually start breaking driveshafts and joints, or worse, and start ripping the spring pads from the axle. Ladder bars are good to help out with reducing the wrap, but if the original proplem isn't fixed, then what have you really gained?

some one needs a spankin, musta been born in the 80's

without reading anything but the first post of this BS thread Id be willing to bet hes got stacked (or a 4") lift block in the rear and his axle is wrapping up. Id ditch the block(s) and flip the shackles. I have no faith in your 89 F150 and 33" tires really NEEDING ladder bars

 

And the hop isnt just from the axle wrapping up, but does contribute. Bigger tires, lack of torque to make them spin freely causes them to slip and grab creating the "Hop". I broke the spring perches and twisted the springs in my 78 Bronco doing this, and broke god only knows how many rear driveshafts. Thats what you get when you have big rubber and a heavy right foot.

 

Id say its much more likely with rear lift blocks (especially stacked rear blocks) than the lack of torque in the motor.

Your statement supports that axle wrap up is a low horsepower problem? WRONG!

Trust me. Flip the rear shackles and ditch the lift blocks and you wont have the problem. Busted drive shafts is also evident of a axle wrap issue.
