How do you replace the Front wheel bearings on a 1997 Jeep Grand Cherokee?

Piece of cake!

SRSly, this is what we call cakework.

1) Jack up the front of the truck ( or the affected side).

2) Remove the wheel.

3) Remove the brake caliper, pads, and rotor.

4) Remove the axle nut. I use a 36mm socket.

5) Remove the three hub bolts (from the back of the spindle) ea.:

5a) You will need a 1/2 12 point inch ratcheting box wrench and larger

box wrench as I use or a 1/2 inch 12 pt. socket and ratchet with

long handle for rich folks who can afford such luxuries.

5b) Force the bolt to loosen 1/4 turn, then retighten. Spray the threads

with penetrating oil, then loosen as far as it will go (not much) easily.

Now curse about Mopar and rust. Ask a sailor for help if needed. Wire wheel or

5c) Go to 5b) until the bolt is out.

6) Use a sharp chisel and hammer to draw the hub bearing out of the spindle. Try not to use the chisel near the bolt holes.

7) Use a sanding disc remove any burrs from the hub mating surface of

the spindle.

8) Use wheel bearing greasre or moly grease to coat the splines of the

axle, the big hole in the spindle, and the threads of the bolts.

9) Put it all together.

10) If you got lazy and didn't do step #7, get a wheel alignment, then

drive for about 5k miles, repeat steps 1-9, then get a wheel

alignment again.
