I purchased a 2007 Automatic Hyundai Sonata 6 months ago and have been advised by friends the rear wheel bearing needs replacing. Would this be covered under the five year warranty? If not, how much would the repairs approximately be? I live in Perth Western Australia. Craig

nope and my guess is whoever replaced the bearing broke or did not connect the wheelspeed sensor

Rear wheel bearing should not be very much. Front would be considerably more. Find a reputable mechanic with a reasonable shop rate. STAY AWAY from car dealerships , they always , always , always overcharge.

ABS is not involved in this.
Remove wheel/brake caliper (swing to side)/rotor, loosen the big center nut and pull the hub off. (may need hammer)On reinstall you NEED a torque wrench and find out the pounds per sq. inch pressure needed. (!20 lbs is norm,too tight will crunch the bearing) Hour and a half job if all goes well.
A good site for how-to's......

Get the mid range priced hub not the cheapie

the work grade ,tutorials,estimate and tools needed are posted on "All DATA" which you will find in most local library .dealers ,mechanics and shops use it as a reference .
good luck!

the rear wheel bearing is part of the rear hub and not serviceable the hub itself needs to be replaced, its fairly simple, and not that expensive,you must remove the brake caliper and rotor to remove it.

Did you remember to release the e brake?

Sounds like brakes hanging, foot on brake, or something that causes brakes to be on all the time, at least a little.

Yes this will damage everything that you described..and more. Brakes will work poorly...

dear friend-replacing the stud is a fairly intensive job,the hub must be removed,so you might have to replace the wheel bearing,you will need special tools to attemp this job.

if its due do it,if the manual booklet recomended,do it pls

1. for drum brakes with sealed hub(all one piece) remove lug nuts and wheel.
2. spray penetrating oil around studs if there is a big phillips head screw visible remove it with impact driver/if not use big ballpeen hammer ,tap on flat of drum near studs(becareful not to hit them) until drum loosens(your creating a shockwave to loosen rust)
3. once drum is off there are 4-bolts coming in from behind backing plate, remove them then hub should be able to be removed w/a little persuation from hammer.

with out sealed hub ,

1. remove wheel
2. remove dust cap,cotterpin,star washer(if equipped) do not re use cotter pin
3. remove nut then washer, wiggle brake drum and front bearing will come out.
4. put nut on shaft tighten 2-3 turns grab drum by sides and pull towards you this should remove drum leaving inner bearing/seal on shaft
5. to replace reverse procedure making sure to pack new bearings w/grease(take drum and use long punch to remove bearing races, use race/seal installer to install new races

with disk brakes

1. remove wheel
2. remove caliper/bracket
3. remove rotor
4. remove 4-bolts from behind,tap old hub out
5. reverse procedure
