i have 37s, 5inch la and 1 inch bl and when i drive it likes to get thrown side to side, all bolts are tighthened trac bar is good wheel allignment is perfect. what to do to fix this squirley problem

 

Does it primarily happen when you hit bumps or all the time?

 

bumps uneven spots in the road or coming out of a turn

 

your caster will give slight flighty feeling if not adjusted fairly close to stock.....and i also have found that with larger tires....if toe is set to spec....it will wonder abit....with a slight toe, it helps take the wonder out....i got the lifetime alignment at firestone...and after wheeling i would take in for a alignment, and they would ask me how it drove and i talked with them....so forth and so on.....talked to the guy for awhile, and he said with larger tires, handling will improve with a slight toe in......i was like ok....so took his advice and sure enough worked......worth a shot...

 

Did your lift come with a drop Pittman arm?

 

yes i am using a dropped arm

 

As suggested, you may check your caster. Do you know what angle it is at?

 

i have the skyjacker non adjustable lower arms and stock uppers, what the easiest way to check caster myself

 

As Robar suggested you need to know what your caster is. Factory is 4.2 degrees and you may want to run more than (6 or so) that if your driveshaft can handle it. What is your toe in? As I recall stock is 1/16 and I'm running 3/32 but was prepared to go to 1/8 if need be. I have been told that on 37's and up sometimes a bit of toe out is required; from 1/16 to 1/8". I have no first hand knowledge of that so take it for what little it may be worth.

Try to be there with the tech when he does the work. I do know that when we mod these vehicles heavily just going with stock specs won't work.

 

i just want to stop it felling like it is dancing when coming our of a turn or uneven pavement
