I've seen a few of these trucks going down the road in front of me and the truck looks as though the front of the truck is in a different track as the back. Or sideways if you will. I've seen old trucks do this figured it was just a bent frame , but not a brand new one . Whats with that?

this was not after happy hour. I've seen it on several different brands but since i will be buying a gmc i guess that i've been looking . Kind of like someone hit the truck hard in sideways in the a** end and it stuck.

As I recall, the front track is narrower than the rear. So depending on the angle you are looking from it may look sideways. I have noticed it myself.

It's called 'dog tracking'. Sometime it has to do with alignment issues or rear end not positioned correctly (it can happen) or it could be from something bent after a wreck. It's easier to see with a very long truck as opposed to a short car.

What is happened is the axle isn't striaght in the back of the truck.. who ever put it in didn't make sure it was square... its just like watchin a trailer do the same thing... a lot of trailers you buy wont track straight beghind t vehicle.. thats why you should always test drive/test pull whatever you buy... I pulled a trailer for a friend once an the back of the 35 foot trailer was on the outside line with its tires while I was runnin' my front tire of my truck on the centre line. its just a matter of adjustment to get it square to run straight down the road

The front axle is wider then the rear axle, makes it look funny.

And it is exacerbated on a lifted IFS truck.

( car motor in a truck) is a figure of speech that alot of heavy duty truck mechanics in my area use. (ie.) ford 351 cammed for a car placed in an f 350 = no torqe had a few of those. Gm 350 cammed for light duty truck placed in a gmc c70 dump truck had one of those. My point was that sometimes an engine that was not initally made for hd work ends up in a truck . Since i planon dumping 40K into a new truck just thought iwould ask. As far as the sideways truck i have seen 2 of them in the last 6month. longer truck, front left wheel on yellow line back right wheel almost on white line, Brand new trucks. Was not drinking and they were certainly ( not right). As far as the lbz , my bad , Guess i should have asked about duromax overheating that i have heard so many people on this site comment on . It seems pretty clear to me that this thread is about some concerns of engine overheating and if my new truck is going to be misaligned going down the road and if it could be corrected. diddn,t mean to wreck your morning.

Optical illusion 100%.
With the front end track being wider than the rear, the longer the truck the wackier it looks especially if it's jacked up and the wheels are further from the body than if it were stock and they're partially hidden inside the wheel wells.

The IFS front suspension on GM 3/4 ton trucks has a wider track than the rear. They've been that way for years. The next time you see one from the late 80's or 90's rolling down the road check it out. People say putting spacers on the back makes the truck handle better. I put some 1 1/2" spacers on my lifted truck, just because the fabtech lift shoved the front tires out even farther and made it look kind of goofy. Spacers fixed that right up!

I think that I have read on the new duramax coming out that the front and back are different widthsbut I believe it is normal. why im not sure?

Sometimes it is the GRADE on the road doing it. If the road is graded to the side dramatically, or if there are trenchs int he road within the track, the rear of the longer wheelbase trucks will grab the trenchs, or the grade of the road will pull the back of the truck down wtih it... you see it a lot on Vans and long trucks......

Ever notice you have your wheel turned slightly while driving sometimes?

When the Army started fielding the M1009 CUCV (Military Chevy Blazer) I was a QA inspector in the main shop and several people came back to us with the same thing about them. When you follow them and you're offset from center they look like they're tracking "doglegged", so we put them on the frame machine and checked the frame alignment. They were straight as an arrow. The front axles are wider then the rear and it turns out that if you view them from straight in the middle of the rear you don't get the illusion, only when you look down the side of the vehicle. It's the narrower rear end that does it, or was in this case anyway. Sure sounds like the same thing to me.

Yes its dog tracking and the different axle widths, but I highly doubt that the front left tire was on the yellow while the right rear was on the white line. PUlling a trailer, esp likea 32 ft long one etc no doubt had it happen and seen it but jsu thte truck itself being that far off is hard to believe.

Measure the width of the front axle versus the back and you will find the front is wider. Looking from the rear, the thing looks will look like it's going down the road crooked till you look at the other side too. I've thought about spacing the rear out to match because it bugs me!

Its that way because of suspension travel, If you were to pick the truck straight up off the ground the distance would be the same width. IFS causes this yes, solid fronts are the same width.
