    The lugs on front wheels my 2003 taca tocoma get very hot. Is this normal? 2.4L RWD, base no options.

    77k miles. front bearings cleaned and repacked at 71k.

    never noticed this before, but generally I dont touch lugs immediately after driving. So, maybe it's always been like that?

    You mention bearings cleaned & repacked. When adjusting the bearing pre-load, cleaned & repacked used bearing sets should be adjusted just a tad looser than new bearing sets. The difference being that the new bearing set will "wear in" as a set and will loosen a very minute amount while doing so. So you could be running slightly tight bearings. That being said, the hubs do run somewhat warm/hot depending on a lot of circumstances (ambient temp, speed, amount of braking, etc). You might jack it up and do a spin test to see how freely they coast down to a stop, keep in mind about brake shoe/pad drag.

    x2 on the brake pad/shoe drag. How hot are we talking about?

    take your brakes apart, caliper slide pins are probably seized and causing the pads to drag or you have a seized caliper piston

    Both sides?

    It's kind of tough to say if that's even the problem, but you would just have to take the caliper off and you can leave the bracket where it is, to pop off the caliper and check the slide pins and piston to see if they're seized should be quick 30 minutes. I've worked on some cars and trucks where the lug nuts were just hot, especially steel wheels that have not a lot of metal between the wheel and the rotor. Aluminum wheels generally have more space between the wheel and the rotor so the lug nuts are cooler

    Also check your wheel bearing for any play
