Firestone alignment

Hows this look. I took it to Firestone. Truck feels fine. I had adjusted my coil overs to compensate for my bumper. Had it realigned. He said he couldn’t get the caster in spec.

3in ultimate toytec cool over lift.

 

I had noticed wear on the outside of my tires after the coil over adjustment. Hence the alignment

 

well It definitely got better but seems like your missing adjustable upper control arms or the alignment tech doesn't know how to use them properly.

SPC upper control arms are my favorite if your just trying to not beat on your vehicle. I have gone through lots of tough terrain without issues and it allows full movement without hassle of caster/camber.

 

Yes sir. Don’t have adjustable UCAs. Toytec said I didn’t need them with this lift. Due to the diff drop

 

whomever told you that doesn't understand suspension. the diff drop doesn't have anything to do with the upper control arm besides possibly a midtravel unit where you want the diff drop to compensate shaft location for the longer down travel.

Adjustable upper control arms or aftermarket arms do three major things
- Allow for caster/camber correction so that your able to get into spec
- give more clearance on the backside for larger tires
- allow more articulation due to better balljoints compared to stock (using balljoints vaguely here as different joint types are used)

 

Roger. Thank you. Good info. Looking at this alignment sheet do you think I need them?

 

Personally I would say yes. 3" lift will cause bind without the upgraded uppers as well so your stock balljoints wont last long (and yes I understand some have been running it for a while without issues) I highly suggest the upper arms. Maybe talk with a different vendor first and ask their opinion but your caster is at its minimums while barely hitting the camber adjustments. Camber is a major factor in tire wear and caster really affects overall drive-ability so it will pay for itself in just the tires and the effort to drive.

 

Does This camber look ok for now until I get some arms. Don’t wanna trash my tires

 

I can also back the coils off a lil. Maybe take her down to 2.5

 

It isn't horrible so unless its gonna be a while I wouldn't bother it too much. adjusting the coils will just affect the rest of the specs and cause need for another alignment.
outside only wear is normal for front tires. its from underinflation or hard/loaded cornering. Toe and camber can wear tires but normally its pretty extreme for toe and very mild on Camber.

These are just my opinions. I highly suggest getting more and making a decision. I know i get the most mileage, the best economy (17.5mpg on 35x12 with rtt and full armor) and the easiest driving truck of the people in my area, due to not accepting "Close enough" for my alignments and tire choices. Keep in mind the economy and tire wear are directly related as well, too soft of a tire pressure and your tires will roll causing bad wear as well as being bad on fuel.

 

I was running 27 psi. Also I do drive like an asshole. I am now at 35. Gonna slow down my asshole driving.
