2002 Toyota Corolla

Toyota does not use a sealed hub assy. You will have to have the old bearings pressed out.
If you raise car, put on stands, grasp wheel and push/pull horizontally and vertically and have no movement, your bearings are probably OK.
I have seen these bearings last 15 years or more.

Trying to use a puller or installer will probably cause more problems.

I wish all bearings would last 15 yrs. Thanks for your advice on removing bearing. Two years ago left bearing shattered and steering knuckle broke in two peices;
I wish toyota design the veh so bearings could easliy be removed and repacked. Since the car is 6 yrs old i will replace bearing to be safe side. The front end took a beating with all the NY city driving especially in Brooklyn area. Sometimes cant avoid potholes; actuallyl they are more like sink holes. Rob

I would suggest using Toyota bearings vs aftermarket.

I have used aftermarket axle seals on my Corolla with little success (leak continued), then tried Toyota seals and no leaks. Even though the Toyota seals are twice the price, I am happy to pay it so I don't have to change them every 6 months.

However, it's your money..........mmprince4000.

Do you mean the seal on both sides of bearing to keep the bearing grease from oozing out? Aren't they just caps with ruber lining on one side? I have had trouble with CV axle seals leaking; maybe i will go with Toyota parts but so expensive; toyota plugs are
$ 15 a peice{iradium}; they should have gold plated electrodes
