i need to fix my camber and caster on my truck. i know you move the upper a-arm to fix the camber but what do you need to do to fix the caster? i cant remember what firestone measured it at but i know the measurements from right to left were pretty far apart. also, if my front spring isnt seated properly will it cause my tires to wear improperly? i think my drivers side front spring might be spun and not in the correct position, which way should the cut part on the top of the spring be facing? (it pops when i jack it up and when i let it down) thanks

 

you move both cambolts on the top a-frame accordingly to adjust caster and camber. 99-06 trucks are the easiest vehicle to do a wheel alignment on but take it to some one that knows what they are doin.

 

i took it to firestone and they told me there is no way to adjust camber or caster on these trucks so i am going to do it myself. i paid for the lifetime alignment at firestone so i can take it to them everyday for an alignment if i need to.

 

what truck is this on?

 

i've had a hard time getting places to do a wheel alignment on a lowered truck before, usually b/c they assume you want to pay the typical alignment price for an atypical alignment. offer one of the mechanics a bribe, and it may save you and him some frustration so you can put this all behind you and enjoy your truck. that's what i would do.

would a precision level help if placed flatly, and squarely inside the rim? i am about to drop my 1991 gmc sierra 1/2ton 3" in the front with 2" belltech spindles and 1" belltech coil springs, and 5" in the rear with 4" belltech leaf springs and adjustable shackle on the 1" setting (might need the full 6" in the rear, will post photos).

i'll post the outcome of mine and exact part #s used.

 

it is on my 2002. mine is lowered 3" in the front with springs and about 5" in the rear with springs, shackles and aftermarket overloads. i have heard about using a level to do it but i would rather have it right at -.5* as per GM specs, i have also heard there is a tool you can buy that measures the exact angle but i have been unable to find such a tool.

 

Tell whoever is at Firestone they're an imbecile and bring it back. Loosen the upper control arm nuts and put a wrench on the bolt head and move it back and forth, moving one side will adjust camber and caster, moving both at the same time will adjust camber.
