Bumpsteer bad. Can someone check my angles

[-96JeepSpeed-]

Doing this puts too much stress on the passenger side knuckle.

Like was mentioned before, check your caster.

Ehh, TONS of people do it, with success

For the second time, his RK steering is set up correctly.

I dont think so. If so thats a prett Fawked up setup, Why the hell would somebody do that??

Can you turn your wheel both ways till the knuckles hit the stops?

It keeps the drag link in the factory location, below the knuckle so the trackbar and drag link stay parallel. The tie rod has a bend near the knuckle so it clears the draglink. If they mount it above the knuckle, then this would require welding a bracket to move the trackbar up too and it wouldn't be bolt-on.

So how does it flex with the Mis-alignment spacers already maxed out on the drag link just sitting on flat ground??

thanks for all the help guys. hopefully i can get the caster angle checked and figure this all out soon

That's not what I was told when I had my rig inspected by an off road specialty shop. They told me if the suspension cycles and your steering turns or jerks during this cycle then it's bumpsteer. For instance, when I would climb over this 1 foot rock, my steering would turn to the left on it's own and I would have to correct it. The cause of it was the drop pitman arm putting the draglink out of sync with the trackbar. Once I removed that drop arm, the bumpsteer was gone and i could cycle the suspension with zero movement in the steering. It made perfect sense to me. Perhaps the 22 year off road vet was wrong........or it's the same thing, explained differently??

Either the 22 year old offroading vet was wrong or you misunderstood him.

he has exceeded the recommended maximum lift height for that steering setup.

x2, that's why I think the IronRock setup looks screwed up as well....

Perhaps I did. I stand corrected and apologize for the wrong info. Thanks for correcting me.

he has exceeded the recommended maximum lift height for that steering setup.

But the thing is, If it were lower, and the heim wasnt maxed out, What do you think it will look like at full drop with/o straps? Maxed out.

Caster doesn't cause death wobble, but it will hide or magnify the real issue... just like a wheel to wheel tie rod, and steering stabilizer will.

Have someone shake the wheel back and forth with the vehicle running while you watch and feel every link, bracket, and bushing under the front end. If you don't find anything repeat with a wheel against something (tree or whatever) to check everything under a load.

If you don't find anything loose check your toe. If that is in spec swap on a set of tires from something that doesn't death wobble.

If it's gone at that point you know your issue.

That is the strangest setup I've ever seen. I didn't think it was installed right at first, but it looks pretty close to the mfg. picture in the directions.

im going monday morning to pull the 2inch spacers out of there and throw some cheap 30 inch tires to drive around on while i work out this suspension and steering.

Hopefully pulling the spacers and running drop brackets will get my control arm angles a little better and maybe help my steering.

That is the strangest setup I've ever seen. I didn't think it was installed right at first, but it looks pretty close to the mfg. picture in the directions. It still seems to me like the tracbar would need to be lowered at the axle end to be "right".

As far as trac bar and drag link; your looking for similar angles AND similar lengths. One can certainly make up for (or hinder) the other to a certain extent. For instance the change in drag link length of our 1-ton setup OTK from stock seem to minimizes the difference in angles.

same with stock steering, it gets maxed out at full droop.

I got the 2inch spacers out tonight and now im sitting at around 6inchs and there a huge difference in handling. rides so much better now. No death wobble on the way home. Putting it on the lift tuesday to wiggle everything and make sure its all tight

 

[ChristmasXJ]

Alright so like I said I took out the 2inch spacers.

It looks like my axle is really angled down. The lower control brackets are angled really bad also.


I just want to get this dialed..... Getting death wobble crusing at 80 on the highway is scary as shit lol

 

[JNickel101]

You really need to get those control arms leveled out. That looks scary to operate.....

Brackets dont really count,but those CA angles are out of this world!
