Hi, replacing the front wheel bearings on any vehicle is difficult if you don,t have the right tools, as the driveshaft and wheel hub (where the bearing is seated) needs to be removed. The hub housing the bearing may have to be heated (depending on corrosion) when the bearing is being pressed out, by using a heavy duty vice , and the new bearing is pressed in using the vice and the old bearing as a guide. I would strongly suggest you refer this repair to someone who has done this before, I personally would not undertake to change front bearings ever again, the first time for me was an experience I wouldn't want to undertake again. All the best.
here is a step by step instructions on how to replace your bearing. please copy and paste the link into your browser for an image.

Removal & Installation
Apply the brakes and hold in place.
Raise the vehicle.
Remove the front tire and wheel assembly.
Remove the cotter pin, lock nut and spring washer from the hub nut.
While the brakes are applied, loosen and remove the hub nut on the end of the driveshaft.
Release the brakes.
Remove the front disc brake caliper and adapter as an assembly, and the brake rotor from the steering knuckle.
Remove the nut attaching the outer tie rod to the steering knuckle. To do this, hold the tie rod end stud with a wrench while loosening and removing the nut with a standard wrench or crowfoot wrench.
Remove the tie rod end from the steering knuckle using Remover, Special Tool MB991113.
Remove the tie rod heat shield.
Remove the nut and pinch bolt clamping the ball joint stud to the steering knuckle.
CAUTION
The strut assembly-to-steering knuckle attaching bolts are serrated and must not be turned during removal. Hold the bolts stationary in the steering knuckles while removing the nuts, then tap the bolts out using a pin punch.
Remove the two bolts attaching the strut to the steering knuckle.
NOTE
Use caution when separating the ball joint stud from the steering knuckle, so the ball joint seal does not get cut.
Separate the ball joint stud from the steering knuckle by prying down on lower control arm and up against the ball joint boss on the steering knuckle.
NOTE
Do not allow the driveshaft to hang by the inner C/V joint; it must be supported to keep the joint from separating during this operation.
Pull the steering knuckle off the driveshaft outer C/V joint splines and remove the steering knuckle.
NOTE
The cartridge type front wheel bearing used on this vehicle is not transferable to the replacement steering knuckle. If the replacement steering knuckle does not come with a wheel bearing, a new bearing must be installed in the steering knuckle. Installation of the new wheel bearing and hub must be done before installing the steering knuckle on the vehicle.
Slide the hub of the steering knuckle onto the splines on the driveshaft C/V joint.
Install the steering knuckle onto the ball joint stud aligning the bolt hole in the knuckle boss with the notch formed in the side of the ball joint stud.
Install a new ball joint stud pinch bolt and nut. Tighten the nut to a torque of 70 ft. lbs. (95 Nm).
CAUTION
The strut assembly-to-steering knuckle attaching bolts are serrated and must not be turned during installation. Install the nuts while holding the bolts stationary in the steering knuckle.
Position the lower end of the strut assembly in line with the upper end of the steering knuckle and align the mounting holes . Install the two attaching bolts. The bolts should be installed with so that the nuts face towards the front of the vehicle once installed. Install the nuts. Holding the bolts in place tighten the nuts to a torque of 40 ft. lbs. (53 Nm) plus an additional 90° turn after the specified torque is met.
Place the tie rod heat shield on the steering knuckle arm so that the shield is positioned straight away from the steering gear and tie rod end once installed. Align the hole in the shield with the hole in the steering knuckle arm. Install the outer tie rod ball stud into the hole in the steering knuckle arm. Start the tie rod attaching nut onto the stud. Hold the tie rod end stud with a wrench while tightening the nut with a standard wrench or crowfoot wrench. To fully tighten the nut to specifications, use a crowfoot wrench on a torque wrench to turn the nut, and a wrench on the stud.
Tighten the nut to a torque of 40 ft. lbs. (55 Nm). Install the brake rotor, disc brake caliper and adapter.
Clean all foreign matter from the threads of the driveshaft outer C/V joint. Install the hub nut in the end of the driveshaft and snug it.
Have a helper apply the brakes. With vehicle brakes applied to keep brake rotor and hub from turning, tighten the hub nut to a torque of 180 ft. lbs. (244 Nm)
Install the spring washer, lock nut and cotter pin on the hub nut. Wrap the cotter pin ends tightly around the lock nut.
Install the tire and wheel assembly. Install the wheel mounting nuts and tighten them to a torque of 100 ft. lbs. (135 Nm).
Lower the vehicle.
Set the front toe on the vehicle to required specification.

Replace the volume control(rheostat) inside the radio. Only way to fix it. I would personally just live with it until one or the other quits working. Then replace the radio.
