Dog tracking?

Hi guys, I was driving yesterday and another guy got out of his truck and told me my truck was "dog tracking", basically from what I've researched means that the rear is not aligned with the front and it travels down the road sideways. I recently replaced the leaf springs and I do so with OEM springs and I've checked to make sure they're tight and centered properly on the pin. Another point of interest is that I noticed quite a while ago that my bed does not line up properly with the cab, it's an older truck and had a few minor scrapes so I didn't think much of it figuring as long as my wheel alignments are good it was more of a cosmetic issue. Because of this I'm wondering if it looks like it's dog tracking but is in fact fine. I'm going to do a few more measurements and I can't get it into the shop until next Tuesday so I'm wondering if any of you have any thoughts or suggestions on what I can do to determine the cause. My plan is to initially take measurements from front wheel to rear wheel on both sides and see if there is a difference. Thanks for any suggestions, alignment issues are not my specialty.

Its actually called Crabbing .

So we have to ask :

Any major accidents

Check rear U bolts closely , rusted ,broken, loose

Check leaf spring hangers , bushings etc

Thoughly check frame for rust , cracks and sags n bends that dont belong

Thanks for the suggestions, the truck has been in no major accidents. I checked all the rear hardware and it seems fine. I just had the frame inspected by Toyota and they passed it and undercoated it. As mentioned earlier I replaced the leaf springs but they seem to be all lined up with hardware tightened. I did grab 2 x 4's and put them under the back of the front wheel and the front of the rear wheel and took measurements. The passengers side measurement is about 1" longer than the driver's side.

I'd double check the pin setting on the leaf springs. It's easy for them to pop in the wrong hole when they're lowered on to the axle.

I'm not sure what pin setting you're talking about, there was a single hole depression for the leaf pack pin to sit in on top of the axle. There were no other holes and the packs are square on the plate.

I remember the plate having more than one hole. One time I was working on the springs and when I lowered the jack, the wheel moved and dropped it in the wrong hole. After I bolted up the u-bolts and took it for a ride, it didn't feel right. I took it back apart and realized I didn't have it positioned correctly.

Garage
Throw some flour on the ground and drive through it to see if your tires follow each other

Thanks @frndrfoe , great idea, and cheap! Hope I don't get the cops called on me when someone spots me coating the local parking lot with flour...

You said you replaced the leaf springs, you could possibly installed one of them incorrectly. I cannot guarantee this but I do believe they are not bi-directional. You may have installed one backwards? Something to look into?

Update...after tearing it all apart I finally got to the problem, the center pin on the leaf packs were not universal and there is a 1/4” difference if they’re not installed properly. There were no markings on the packs stating this and given the minor difference I didn’t realize it when I inspected them when initially installing. There is only one pin location on the axle so that was never an issue. It was frustrating that there wasn’t an indication highlighting this but it did teach me a lesson to inspect thoroughly. Thanks to all who offered solutions.
