When i take a left turn i hear a squeak and it starts to grind

It sounds like you have a front bearing hub assembly going bad. The easiest way to check for a bad hub is to jack the front wheels off the ground. For safety install a set of jack stands underneath the frame. Now one at a time, grab the tire/wheel assembly at the 12 and 6 o'clock positions (not 9&3) and rock back and forth to check for play. If you find excessive play on one of the hubs you must change the assembly as it is a sealed bearing. Look up the correct part for your truck on rockauto.com. Youtube has many videos on how to replace the hub. It's not a very hard job to do with basic hand tools. Good luck.

You probably have one or more bad ball joints in the steering on the front end. This truck should have grease zerks on the ball joints. If you greese everything and it gets quite, then it is the ball joints. However a WARNING. If the ball joint was squeaking and grinding, it should be replaced. Have a good mechanic check it out. Its hard to do yourself without the proper tools and knowledge. This is possibly a dangerous situation and something could come loose on the front end and you lose the ability to control the vehicle.
There are other possibilities, like snow and ice build up between the tires. Or bad wheal bearings. Jack the front end up, and rotate the wheels. They should spin freely with no noise. Next grap the wheel top and bottom. There should be no play.

If this is a four wheel drive vehicle it is a possiblility you have bad CV joints or universal joints which transfer power to the wheels. To check this, engage the 4x4, set the parking brake, and jack up the front end. Grap the wheel and try to rotate it, it should not move at all. . If the CV joints are out, you should be able to hear noise when you do this.
