New style bearings are all pressfit bearings, if your hub came right out of the bearing assembly, it is time for the whole assembly. The hub assembly has a locking ring that holds the outer bearing race inside the hub, after the wheel hub has been pressed out. Then, after the lockring has been removed it can be pressed out and the new bearing can be pressed back in and then the lockring reinserted. Then the wheel hub gets pressed in.

I did a quick replacement of a bad rear wheel bearing/hub on aKia ... How to install front struts on a Kia ...

If it is a rear wheel drive predominately then yes you replace the front vac hubs only as the rear is constantly driving, is it a east west motor or north south , that will tell you a lot

the vacuum hoses or wheel seals are leaking in the front wheels. they are vacuum operated. the dealer has kits you can buy to convert to manuel locking hubs, they had alot of problems with the vacuum hubs

a quick fix to solve the problem with the 4wd not working on the sportage is fitst check the vacume soionoid is working lockated by the suspention turet on theL/H side of the engine bay, then, chech hoses going to the hub, if there is still a vacume leek from the hub remove the 6 bolts from the outer hub locker place in vice remove the circlip, remove the spring, remove the spline gear then take the spring and swap it around so that it gose under the gear so that it is in conatant mesh/ lock, build back up and fit, it means the front axle will be live all the time but you will still be able to select 2 /4wd,,

Do you have automatic locking hubs? Do you need to turn hubs on wheels in order to have 4 wheel drive work? If all you do to get in 4wd is move shifter, then you have automatic locking hubs. The clicking indicates that the hubs are not fully disingaging. To check, block rear wheels, jack front up, and turn tire. the axle should not be turning...if it is, hub is still ingaged....time for new hubs.....if hubs are bad, and you want to save money, you can purchase a set of manual hubs made by (WARN)...its more than half the cost, but you will have to turn hubs to lock and unlock manually. Note...you still need to use the gear selector to put and take out 4wd.

wheel bearing bad.

replace your hubs to manual hubs thats what happened to mine, you can get them at any auto parts store.

That light sounds like a differential lock or 4-wheel drive. This is usually found in 4-wheel drive and all-wheel drive vehicles. Being the light is "GREEN" and not amber or red tells me that it's not an abnormal problem.

Look around your dashboard or gearshifter for a button labeled 4x4 HI, 4x4 LO, 4x2 HI. sport/off road button, or a second, smaller shifter. Switch them around a little, and if it is a 4x4 selector, be sure when you drive on paved roads to have it set to 4x2 HI. 4x4 HI should only be used if you get stuck to help you get out (snow/mud) and 4x4 LO is only for off road driving (trail blazing/rock climbing/4-wheeling/mud bogging,etc.)

Also, check for any switches labled "DIFF LOCK" or 'AXLE LOCK". In most cars a green light is normal operations.

I hope I could help you find a solution to your problem.

I have the same problems but found the problem. Put a vacuum pump on the hub and see if there is any. I have one that has 30 inches of vacuum and one with zero. The only solution I found was to buy a used one from a salvage yard. The hand vacuum pump is only $40 but you will save over a $1000 doing this.
