Pulling right in 4wd

2014 TRD or pulling right in 4wd after jba uca and alignment. Could this be because on side has 3.8 caster and the other is 4.3?

 

Possibly, why not try to get 2.5 - 3 degrees caster on both sides?

 

i told the tech to set it between 3-4 degrees and the numbers above are what i got. Thought it would be okay but if its causing it to pull then i will take it back. Ihave looked under my truck and everthing seems fine. The uca and alignment are all that changed.

 

thanks

 

Do not drive on dry pavement in 4wd !!!!

 

I didnt drive on pavement in 4wd.....

 

Do you have a print off of the alignment? I see no reason for it to pull with that much caster. If the camber isn't set right, it can pull. Before I put my new suspension on, I set mine up with 3.3 and 3.6 caster and 0 camber and it drove great. If I remember correctly, it has 2.7 and 3.0 caster and -0.4 camber on both sides now and it wants to drift to the right a little. I didn't feel like messing with it at the time so I just did a quick toe adjustment.

 

I do but cant load it at the moment....

left right
camber -0.2 0.1
caster 4.0 4.3
toe 0.01 0.01

 

Finally, someone else who knows this word exists. You may be the only other person I've seen use it in the real world.

 

Thought the left side was 3.8 but it is actually 4.0...

 

It's only a slight pull on dirt road in 4wd. If im on gravel or mud you can't even feel it. Just was curious because it tracked perfectly straight before.

 

FYI - perfectly fine to run 4WD on pavement "in a straight line" - in fact, Toyota recommends:
Four-wheel drive usage frequency - You should drive in four-wheel drive for at least 10 miles (16 km) each
month. This will assure that the front-drive components are lubricated. Page 180 in my owners manual.

 

That slight difference shouldn't really be noticeable. I had a hard pull to the right (I too have caster that's a bit off from side to side) and gave my mechanic a bit of an earfull - but didn't have time to drop off the truck to have it redone for awhile. When I rotated my tires, the pull totally went away. I'd forgotten about it until reading your post.
