Alignment issue need help!

So my km2s have been crowning (outside wearing), my tie rods are good and i have replaced my steering rack bshings. All of my numbers on alignment greened out but the sai is -2.6 which is not supposed to be according to tire kingdom (wont be getting anything done there again). Why would it be off this much they said maybe be something bent. I believe the wear is caused by the camber being off and they didnt even put a wrench on them but i saw with my own eyes that the camber greened out on the machiine....wtf is going on? cant afford tires to wear. Any thoughts appreciated....

 

but supposedly 1 gen tacos with 3" of lift will align fine.

 

plus they didnt even touch the camber adjustments

 

well next time i align it i wont be going to a diff. shop. a local 4x4 shop that deals with toyotas alot

 

i will ride on them and see if this alignment helps.....does anyone have their specs with 3" lift on a 1 gen?

 

sai is an angle that indicated a bent suspension part

 

well they said it was way off but i don't know what is bent unless the frame is because it drives very straight and the suspension rides good just the tire issue with the crowning. is there anyway to know what is bent?

 

just read it could be my steering knuckles bent? would this be causing my crowning?

 

Steering knuckles to me would be for Solid axle..... Not ifs

Wheel bearings and bad balljoints can cause issues like this as well. How often do you rotate your tires?

 

every 3000 to 3500 miles so it has to be suspension related. i mean it could be bad ball jointsit does have 216xx miles on it.

 

That was the case with my truck. The lower balljoint was toast, but it didnt knock or cause any other issue while driving.

 

Maybe the SAI is off because of the lift? It doesn't have to be bent, just different from the way the factory designed it. I believe that measurement has something to do with how much the toe changes when turning the wheels. If the wheels are toeing in when you turn, that could certainly cause outside shoulder wear on both tires.

Taking it to a shop that deals with modified trucks regularly sounds like a good first step.

 

ya well i will ordering some new moogs soon then getting it aligned again...i think it might be ball joints. i thought my tie rods were bad but i lifted my truck front end up and yanked on the inner and out rods and there is no movement....maybethere is movement from the weight of the truck though?

 

Best way to check ball joints is to take the weight off the front suspension and also take the spring tension off the joint you're going to check. I do this by supporting the truck on jackstands under the frame, then using a floor jack under the lower a arm to get as much spring tension off as possible. Then give things a shake.

For tie rod ends, leave truck on ground and get someone to turn the wheel back and forth slightly while you look for play.

 

I take my truck to a mechanical alignment shop and the guy checks it all by hand. Do not! I repeat do not trust a douche bag behind a machine lol. Oh and the guy said my frame was bent and showed me how he had to adjust one sides camber way past the other side and he still got it to drive straight and it's wearing great.

 

well i am going to tire kingdom one more time since it is paid for but a different one...getting specs will post them then if i could get some feedback then if need be i will go to the 4x4 alignment shop that i take my Bronco to...if the sai is then still out of wack i will do my ball joints even if they arnt causing it they need to be done anyways. Thanks guys
