bump steer correction
« on: February 07, 2005, 01:59:24 PM »
I currently have an 87' samurai with a 2" shackle lift and 31" tires and have suffered too long with bump steer and wandering on the street (highway driving can get scary at times) .
My question is will the 4.5" pitman arm from roadless gear be the right choice or should I get the 3" pitman,I'm afraid the 4.5" may be to long of a drop to work properly with only 2 inches of lift.
I'm on a budget so the high end steering systems are out of sight for the moment but I am planning on a SPOA w/wrangler springs in the future.
Any info is greatly appreciated!

When I read the thread title I thought you were talking about my Ex Girlfriend...   ::)

Whenever her Ford Probe would start steering too much in one direction she would "Correct" the steering by "Bumping" it at about 20 Miles Per Hour  :o  into the curb on the opposite side of the road to which it would veer...   :-/

She IS a blonde though... ;D

Yeah, what fuelish said. Drop pitman arms will not help bumpsteer. Get a hi steer and be done. Check out Acme adapters, its the most reasonable.http://www.acmeadapters.com/flash_content/launch.html

I'm interested in that ACME set-up too, but maybe also stay SPUA ( depending on the way the 33"s behave offroad after the Calmini 3" Shackle Reversal, 3" IronMan suspensionRaise and 1" bodyliftkit ), so I sent them an Email about  that and to  ask how much shipping would be to the Netherlands, Europe.

They should work, but why not just do it the right way and get rid of the 2" shackle and go spring over ?

yes, it will. Huppo on this board is running TT's hi steer SPUA. The spring is farther down so why wouldn't it work?

A panhard does nothing for bumpsteer.

I think they are using Mercedes steering arms for the crossover.  I'm sure you can find some of those over there for cheaper than you can buy the system.

Thanks for all the advice!! :)
I'll probly be ordering the high steer next week.

As for going spoa I plan on getting the jeep eater setup but that will be a while as I have a baby on the way in a few months and that tends to lighten the proverbial wallet a little...lol.

I installed the 2" shackles about a year ago because I got a set of 31"/ 10.50s for free and wanted a lil more ground clearence for the trail.

At least you have a plan, the drop arm only fits one type of steering box i.e. power or non power so if you were to buy it and then wanted to go power steering you would of wasted some money,I have trail tough steering on one of my samurai's and rocky roads on the other(there early style, yuck)but they both work good,sky makes a good one also.

Jeff answered me ( very quick ! ) and it does work SPUA and SPOA ! Shipping is not too bad, so I think I'll be ordering soon ( just have to check how much customs will be  :( )

Received another Email about another question I had. When I decide to go even higher doing SPOA I can use the 3"dropped pitman arm I already have. Jeff also states that the backspcing on the rims should not exceed 3.5 ". He can accomodate for different types of axles and for powersteer.

Hmmm, can't seem to modify my own message from another computer  :-/ Well, I have a question just to be sure:

When measuring backspace of a rim, do I measure from the flat part where the wheel attaches to the brakedisc to ( eerrrmmm, how do I describe this  ??? ) where the straight piece of wood is I hold over the inboard outside of the rim ? With that last part I mean that I hold a straight piece of wood over the rim, laying it on the rim itself so I get a straight line over the centre to measure to from the flat part of the rim..................................................................I don't even understand it myself when I read it back, but I see no other way of describing it  ;)

[edit] I have to of course keep my 1"wheelspacers in the total sum of backspacing I think ? Well, then it can't be a problem, the rims are only 8" wide anyhow, so 3,5" backspacing will be the least they will be [/edit]
