Alignment issues after 5100's @ 1.75"

Hi all! Been a while since I posted due to the fact I haven't really done much to the truck since I purchased it (2015 4x4 DCLB TRD Sport). I recently started my build though... Bilstein 5100's @ 1.75" up front and a 1" block in the rear to achieve a decent leveled look. Also, swapped out the stock wheels for 16" Pro Comp 7032 with 265/75 BFG KO2's. (Swapped on the KO2's after finding that 3 of my originally purchased Falken Wildpeak AT3's were defective).

Anyway, this is where my issues began, and now my alignment hasn't been right since. My truck pulls right after letting go of the wheel...The truck doesn't shoot to the right, but it starts to drift to the right within seconds after letting go. The shop I had do the alignment has now checked it and redone the alignment twice, but cannot correct it from pulling to the right. Attached is my recent alignment printout. At this point I may just have to take it to a local 4x4 shop or an independent shop to see if they can do better. Anyone else experience similar issues after installing 5100's? Any suggestions?

Thanks!

 

Someone correct me if I'm wrong, but isn't the caster bias supposed to be the opposite of what his is now? The caster bias can be used to correct the pull, but I believe more caster is needed on the passenger side vs the drivers side to do so.

 

Thanks for the replies in advance btw... I am not well versed in alignments. I have 30k miles on truck. I don't see any reason why I should have these alignment issues yet, other than a problem with the 5100's, bigger tires and aftermarket wheels that were just installed.

 

^^^this.

Have them lower the camber)closer to 0 on the driver side which will also lower the caster, but the caster still needs to be slightly lower or at least the same on the drivers side. It's pulling because the caster was incorrectly biased to account for road crown.

Also have them lower the driver side toe wtf

 

^^^ Thanks!

Much appreciated. I'm doing my best to research and try and understand all this now. All suggestions and comments are appreciated.

 

IDK if this helps, here's the alignment numbers I got a week ago after my lift was installed.... I have 265-75-16 bfg a/t ko2's.. billstein 5100's set at 2.25" (the top setting) a rear 1" AAL in the rear, stock springs, stock uca's.. No alignment issues at all. Drives straight as an arrow. Your total toe in the front seems higher than mine, they probably just need to put it on the machine again and re-align it better.. or take it to another shop if all else fails. Hope this helps!

 

That's one of the worst toe&go alignments I've seen. Were your LCA eccentrics seized? I ask because they didn't adjust them. At all.

 

How much lift did you get from the 5100s?

It's hard to tell from the picture but it looks like your front is higher than the rear. Maybe the spring seats are upside down and your getting a lot more lift than youre supposed to. This would explain why you can't get a good alignment. @Daria has 5100s at 1.75 if I'm not mistaken. Maybe she can chime in on her alignment.

 

With 2.3° caster and .6°+ camber I doubt he has more than a 2" lift. If the perch was upside down he'd be pushing a 4" lift with much lower caster and higher camber.

 

Just throwing that out there.

 

Just had another independent shop fix my alignment today. They got it perfect. Left the print out at work, but I'm driving straight as an arrow now. The 5100's are set at 1.75 and I have a 1" readylift block in the rear. The picture doesn't really show it, but I have a slight rake in the rear. I have 1.5" AAL, just need to remove the blocks and install it. Jumping up a tire size, the bilsteins and the block gave me about 2" in front and 2.5" in the rear.

 

Here's another pic. It does almost look like a front rake, must be the street. Still can't really see it, but it's definitely not nose high. The rear is about .5" higher.

Thanks again for all the replies!

 

lol no problems at all, it drives straight. Nothing was seized

 

I guess if you're happy with it that's all that matters. According to the numbers it's a piss pour alignment and I'd take it back to have it fixed if it were my truck. Your caster isn't even near being in the lower range of spec (which is still shit). Your camber is too high which will eventually cause premature tire wear on the outside.

 

Toe at 0 or factory spec
Camber at 0
Caster as close to 3.0 positive as possible
This is what you should have as your alignment specs

 

Not sure if this means anything or not, but my tires are 265/75/16, which is slightly larger than the 265/70/16 specified range. So I'm not too sure if the specified range numbers are correct. Or if that's all they could go by. Any ideas?

 

Tires won't have a factor in wheel alignment assuming the tires have no issues and are inflated evenly.

 

The issue is they didn't even bother to adjust the caster or camber. They adjusted toe and sent you on your way. Adjusting caster and camber takes some extra work so they were just being lazy.

It pisses me off seeing alignment sheets like that because people pay good money for alignments and these techs don't even bother to perform them properly.

 

Would having a truck that's not 4x4 having anything to do with the alignment being off as far as putting the Bilstein 5100 at 2.5?
