Icon4 Rear End Thump/weird smell

Sorry, I don't know what forum to exactly post this since two things happened at once so i just post here. Well anyway, I put my truck in drive to go to work and i didn't even hit the gas, truck just rolling, i hear a very loud THUMP in my rear end. Put it in park, got out, checked everything and seemed fine, got back in and off to work i went. I get to work and i get out and smell that smell of like burning electrical stuff or like a heated up RC car like that smell. Looked around and i found the smell coming from my Rear Left wheel, WEIRD.
On my drive home from work truck drove fine like it did earlier no thump but that smell was still coming from the rear left tire....i am clueless.

I know that thump had something to do with it but i haev no idea what the heck is going on the truck drives fine just smells terrible from that rear drivers side wheel which clearly isn't normal.

Anybody know or think what may be going on?
Thanks guys.

Pull the wheel and check your brakes. Could be that your brake is dragging just enough to get hot. That thump could hve been somthing inside the drum braking.

That would acctually be the first thing to check i would think, if your wheel cyliner isn't contracting it will make the shes stay out against the drums

A rear end thump and a weird smell usually indicates flatulence.

Yhea, I've seen many big trucks burn up after the driver used to much brake down a long hill and got them hot. Next thing you know it's not the brakes smoking but the truck burning.

all fixed. my left drum was the one that made the noise. something broke inside and was rbbing so created the smell and i didn't even know but the right one got checked and the wheel cylinder was gone and brake fluid everywhere so just replaced both sides.
Thanks for the help
