I just had my truck aligned today. I tried to get the shop to align it to the specs that I found on the site from the chrysler tech but the shops machine read differently I guess. The truck used to pull really bad to the right and the specs were:
Left wheel: Right Wheel
Cas: 4.1 Cas: 4.4

Now they realigned it and the truck still pulled a bit right.
New specs.
Left cas. Right Cas.
4.0 4.6
They wound up flopping the two front tires and now the truck pulls a bit to the left. Its much better then it was but I was under there when they were aligning it and saw exactly how much they moved everything. my question is should I leave it or should I get under there in my drive way and adjust that right tire a bit farther back? Are those specs ok??

Left cas. Right cas.
4.0 4.6

Left Camber Right Camber
0.1 -0.1

Left Toe Right Toe
0.05 0.05 Total 0.10



The cams on the lower control arms are pointing in complete opposite directions too btw.

The truck also has 22" rims and 285/50/22 terra grapplers. I think it works out to be a 35" tire.

 

I have had that happen many times. Particularly with oversize tires, & bias ply's. Stock tires not so much, but it happens. If you rotate the tires, it may fix it, 'till you rotate again, or buy new tires.

 

If I flip the left front back to the right front it will pull to the right again.

 

sounds more like a tire problem to me. try putting the spare in place of the tire thats giving ya trouble.

your caster was good before they touched it, its not an alignment problem your fighting, all cars will pull the side of the least caster and lead to the side of the most camber, as far as the cams on the axle......dont worry about it, you cannot twist a solid axle, those are there for pinion angle, but it is possible to get a small amount of caster out of them but not much like .3 degree's, you have a tire problem

 

if the tire on the side it pulls to you can have the tire flipped over on the rim 9 out of10 times that will fix it

 

I had them redo it because it started pulling hard left. Put the front tire that was pullin on the rear and realigned it. It drives good now. What do you all think of these specs::

Left caster/Right Caster
3.5/3.9
Left Camber/Right Camber
0.1/0.1
Left Toe/Right Toe
0.0/0.05


I tried to get the right toe to 0.0 but it kept changing the other side. plus it was closing time so I said screw it and got it close as I could.. Also the cams are pointed in the same general direction now..

 

Anyone?????

 

I had to rotate/swap tires around three times on our '07 before I got it to steer right. The rears were about half gone when we bought it and the fronts about 30% left + one going bad on the outside edge if it didn't get lined up pretty quick. I doubt they had ever been rotated before that. It went like this:

Rotated, swapped side-to-side, balanced, aligned, rotated again, then the driver's rear to front swap, ending up with the good ones on the front.

Major PITA.

 

Looks fine but a lot of people run a little more caster. i have mine at 5.5 and it helped return to center feel a lot...
