Need to see alignment spec sheet they gave you.

If you still have it.

 

Yup, without knowing the specs then no way to see what's going on.

Booger is that there isn't much adjustability in the doggone thing.

No camber adjustment, no caster either IIRC, about all there is is toe adjustment, short of going with offset ball joints.

Mine is a touch out of spec, camber off on the left side, and it's wearing the inside edge of the tires quicker than the outside, but it doesn't pull.

Not far enough out of spec for a warranty fix, and not worth spending the big bucks myself to correct it, so I'll just flip the tires on the rims so it will wear the high side down.

And OP, that is something to try, to try and correct the pull, is flip the tires on the rims and see how that does.

 

Camber isn't adjustable.

But caster and toe are.

 

I don't need your sheet. Take a picture of your caster adjustment bolts on both sides and post them on here. Just had a lot going with all this between both of my trucks. I can align them in my driveway now and they both drive strait. If you need more details help PM me and we can talk off the forum.

KBoom, Mine has slight pull to right also but tire wear pattern is just about perfect. If I remember right, the way to correct slight drift right is to increase positive caster on opposite wheel. Is that what you did? I did this on my old Chevy and had it so I could let go of the wheel for a long ways if I wanted to.

 

If you try to put more then about 1/2 deg of cross castor on a radius arm truck it will start to lean. As Kboom did you should be able to get it to drive straight with castor the same on both sides.

 

Try cross rotating your front tires. May have a tire pull. When you cross ratat the front tires it will either go straight or pull to the other side.

 

I rotated the tires and crossed them. No difference.

 

Find someone who will adjust your caster to spec and who will also mind the ride height while doing it. It can be done. I do it at least 5 time a week on solid front axles.

 

Out of curiosity....how is the caster adjusted on these (4th GEN) trucks??? I know where the bolts are....just wondering about the actual procedure...

Is it adjusted with the weight of the truck on the front wheels while on the turning plates??

Is it adjusted with the alignment machine jack stands on the front axle with wheels suspended in the air??

Is it adjusted with the frame supported, and the axle "drooping" ??

Thanks !!!

 

How are the tires wearing? Could be an issue with the brakes also.

 

Tires are wearing normal. The alignment guy said he couldnt see any abnormal wear.

 

2015 3500 dually. Pulls to the right. Seems to pull worse when accelerating.

I have had it aligned and all the stock tires rotated.

If you have the Alcoa's....I assume they simply rotated side to side (fronts).

If you have the steel wheels.......was the air pressure adjusted when rotating?? Was the air pressure even checked by the alignment tech??? Prior to test driving for any alignment issues, a good alignment tech will check tire pressures first-----before test driving it.

And that's the kicker, finding someone who is really good at their job, knows what they are doing and gives a darn about doing a good job.

 

Vehicles will pull towards negative caster. The more forward the wheel is the more positive caster will be.

 

First thing first. CROSS ROTATE FRONT TIRES!!!

 

First thing first. CHECK & SET ALL TIRE PRESSURES!!!

Fixed it for ya.... :S:

 

Mine is pulling to the right and I am starting to see scrubbing on the left outer side of the tire on the drivers side and inner on the passenger side. I figured it would be the other way around, I have 712 miles on my truck.

 

I'm going to guess the negative toe is too much. The passenger tire is dragging and the driver tire is fighting to compensate.

Definitely take it back to check alignment, if you haven't done any lift or modification yourself. Make sure you check tire pressure and keep it exactly what the manual specifies in case the dealer looks for any excuse to deny coverage.

If the tires are worn, and it came that way off the dealership, those should be replaced as well. Not an unreasonable request considering how much these trucks cost.

 

Wow guys! I didnt expect this thread to get so many responses. Currently driving to TX. I'll check back later when i stop for the night an try an answer the questions.

 

Yeah, I watched the guy when he checked mine and was wondering why he was rolling the truck back and forth, now I know!

 

See, this is why I love this forum. I can learn more here than several days of goggling, lol.
As I posted on first page, my truck has had tug to the right since the day I brought it home. Also tended to wander a little. Tires are wearing pretty darn good though for 28,000 rotated once. After reading these post, I rotated tires today and put more positive caster in right side. It's almost neutral now with no wander and ride height looks good. I don't think they had it right from the factory. I'll let it stay like this for awhile and see how tires wear. If I see abnormal wear I'll pony up and let the shop align it. Problem is just as you guys have stated, its hard to find someone who'll put the time and effort into getting it right.
Thanks again for your replies. :thumbsup:

Edited to correct for typing camber instead of caster, thanks Ltngdrvr

You mean caster, right?

Camber is not adjustable on these trucks.

 

when you guys talk about left and right sides, which sides do they correspond to?

on driver side, when rotating caster cams, which direction is which +,- ?
is rotating towards 3 o’clock pos or neg?

how about the passenger side?

thanks

 

On driver's side, rotating towards 3 o'clock is positive. On passenger side, negative. Reason is, moving the bottom pivot point forward gives more positive caster and backwards gives more negative.

 

Sides are determined by the orientation as to when one is in the driver's seat.

Left side is driver's side.....right side is passenger side (assuming here a left hand drive vehicle of course).

 

Thanks to both you guys for your input, I really appreciate it. From what I'm hearing, Kboom, you have a perfectly aligned axle from replacement while something in my setup is either bent or borderline on spec. The cross settings of the cams does make it drive neutral, but just barely. I plan to take it by the dealer since I'm still under warranty to at least get it documented. So far they've been pretty good to deal with. I've also got oil showing around the front crank seal and need to show them that also. Thanks again for your comments.

 

Have you cross rotated your front tires yet?. I've done alignment for 5 years in the past at Sears automotive. If the alignment specs are good and the vehicle still pulls it's usually a tire pull.

 

The adjustable ball joints can do wonders. On our 2015 it pulled enough to keep you on your toes and after biting the bullet and shelling out the dollars it drives fine and the original equipment tires got about 60,000 miles on them.

 

3700 miles and mine is pulling to the right. Have an apointment on 24th at the dealership for alignment. After reading some of these posts I'm scared. It's covered under warranty and first alignment is free with in 12months /12k miles.

 

Got in little sooner. Here is the report. It still feels like it wants to pull to the right. I don't know if it's the slope of the road or me. I also cross rotated the tires.
Called dodge, but they were busy. Left a message and haven't heard back.
The dealership actually subbed it out to a near by shop.

 

Vehicles will tend to pull to the higher camber side of the vehicle or pull to the lower caster side. Your Readings look dead center.You will drift to the right. In an alignment you typically want to see higher camber on the left side to compensate for road Crown .Camber is not really adjustable on these trucks. You could lower the caster on the left side slightly to help compensate for road crown. I Did alignments for for 5 years in the past until I started working on forklift equipment.

 

Readings look good. I would just forget about it and drive happy.👍

 

They changed nothing other than 1/16 inch on the toe. Waste of time imo. Then again anyone who still does toe in inches shouldn't be doing alignments. Obviously you'll end up back in a shop since your troubles continue. Request them to lower the caster on the left side by .4 degrees. Then request your total toe be set to .10 positive! .3 on the left and .7 on the right. Both positive.

 

So what unit should that positive 0.10 toe be, if not inches??

 

It is the disconnect axle that causes it. Only way to solve it is manual hubs, or put slightly more air in your passenger side tires. Basically there is friction in the t-case that causes the front output to turn, and driveshaft and differential. THis assists the front driver wheel in rolling more easily, whereas the passenger side is completely disconnected, and therefore has no assistance, dragging more, causing it to pull. That is why all of our trucks pull.

I put 3 psi more in my passenger side tires, and it doesnt pull anymore. Different source of reducing drag, but effective all the same.

 

Thanks guys
I'm going to pay close to attention to tire wear. I'll take a pic and post from the tires that were in the front. It was the outer shoulder and only the one side (back side) of the lug that had more wear.
This was the front right.

This is what it should look like

Again you will have different wear from left to right because of the different drag caused by the disconnect axle. The front right will always wear worse because it naturally is dragging more since it is not being assisted by the forward rotating driveline. Only way to deal with it is rotate every 4k miles or less.
