alignment specs

Hey guys
Im new here.
Cant seem to find a straight answer,

I've got a Approx 2in lift with dobinsons struts and JBA upper control arms, Im wondering what caster spec did other JBA uca users has set caster to??

Jba says around +3deg but i find my truck to be quite unstable on the highway. Everything suspension part is new in the last year and alignment was done twice.

Im on 285/70r17

Thanks!

 

How fast are you going on the highway?

 

60mph-65. but the symptom is there even slower but its not as disturbing lol

 

What are your current alignment specs? Also, have you replaced the steering rack bushings?

Any other non-oem parts specifically alignment cam bolts or lower control arms?

 

bearings and LBF are oem, Uca and Upper BJ are JBA, tierods are non oem, LCA are oem with moog bushings and cambolts, rack n pinion bushings has been replaced a month ago with moogs.
Alignments specs are stock except for caster at 2.8, originally it was set at 3.6 with the jba and got it down hoping it would help me out, but did not make a difference.
Only parts that were not replaced, are inner tie rods and rack n pinion but I cant find any play in them.

 

What's the toe set to? You probably want about .15-.25 total toe-in.

 

Alignment info you probably want is in this thread. Check the suspension section. Straight out of that guy's ^^ finger.

 

That, my friend, was helpful lol thanks a f***** lot

 

Do you have your alignment print out?

Most around here will suggest always sticking with OEM Steering and Suspension Components.

 

Not only that, but Moog had that big recall on their lower control arms, premature failure.

 

yeah well lower control arms are oem but with moog bushings lol Its going into the shop to check everything. I just cant properly check suspension by myself on the floor lol plus its getting cold... Ill look into the alignment specs and report later.
