Got grinding noise in front end at no particular speed or anything. replaced the hub assembly and the half-shaft so all the bearings are new but still get grinding noise every so often. do you have any ideas where to check next?
Several possibilities. Sound transmits through metal. The rear Emergency brakes will lose their lining and the linings fall into the rear brake drum. They will often pulverize the material and the piles of debris will shift when backing up and repeat the process going forward.
Rust on the front rotors. Constant battle. Can rust in 3 days enough to make noise. Sticking caliper or rubber brake hose is breaking down inside and blocking brake fluid return. Fluid has pressure to tighten caliper but relies on gravity/suction return. Rubber brake hoses internally can form flaps which act like 1 way gates.
Check other front axle for same parts, maybe 1/2 shaft is failing.

I am assuming this is an all wheel drive. That being the case you probably have an axle CV joint going out. If you hear noise when making a sharp left or right turn and accelerating that would more than likely be the problem. And, yes this is a serviceable part. Easy to replace if you have the proper tools to accomplish the task. Good luck.

The hub bearing is usually pressed in and can be pressed too much and damaged.
Also,you may want to check to see if your brakes are worn out on the front which could also be making this noise.

The bearings should be inside the drum assembly.The brakes do not have to come off. The bearings may have to be pressed out if they are sealed type bearings.
The front wheel bearings on your Dodge Dakota allow the wheels to spin freely on the axle spindle. These sealed bearings may cause noise once they wear out, develop a pit on the races, bends and other damage that interfere with wheel performance. However, the front bearings form a single assembly with the wheel hubs and they should be replaced as a single unit. Fortunately, installing a new assembly is not a difficult process.
Before raising the front wheel(s), loosen the half shaft nut using an axle nut socket. Then remove the wheel/tire assembly and the half shaft nut. If your particular Dakota model comes equipped with an Anti-lock Bake System (ABS) sensor, remove the sensor form its bracket and move it aside.
Now you are ready to remove the brake caliper and rotor. Make sure to secure the caliper to the coil spring using a piece of heavy wire. Do not let it hanging by the brake line to avoid damage to the brake hose attached to the caliper. With the caliper and rotor out of the way, you have access to the hub/bearing assembly mounting bolts.
On some models, you can only access the hub/bearing mounting bolts through the holes in front of the hub/bearing assembly. Rotate the assembly by hand as you loosen and remove the mounting bolts. Once you remove the bolts, you can detach the hub/bearing from the steering knuckle and halfshaft. If the bearing assembly seems stuck to the halfshaft, use a 3 jaw gear puller to remove it.
