Never hammer a bearing. It is not designed to take the shock load that hammering produces. Youll damage the race causing premature failure.

It is always best to press them in . set the bearing on the hub place a piece of flat steel on top of it and a piece on the bottom of the hub use a c clamp to press it in . make sure it is going in straight!!!!!

Rear wheel wobbely


Not enough info here. Is it the rim or the hub that is wobbly? If the rim is out of true (and not actually bent) the spokes can be tightened to bring it back into true. If the hub is loose then the bearings need to be adjusted. Either adjustment can be done by your local bike shop for $10-20. A broken spoke can also make the wheel go out of true, this will cost a little more to fix.

2007 ford sport trac rear wheel bearing replacement


Jeff is describing how to replace the front wheel bearings. In the front, the bearing is part of a "hub cartridge". Randy is describing how to change the rear bearings on a truck with a "dead" rear axle. The sort of differential which is one massive cast iron assembly from rim to rim. However, your truck has an IRS [Independent Rear Suspension] design. You need to remove the wheels, brakes & the complete rear knuckle assembly. To remove the bearing from the knuckle requires a hydraulic press and a "knife edge" bearing removal tool. I doubt that you have these tools available. If not, find an auto parts store or auto machine shop with these tools. They can press the old bearing out and install the new one for you. Then you can reassemble the knuckle assembly from that point on. The video linked below should help you.

With the knuckle off, you can easily replace the ball joints at the same time. Odds are you will ruin the original ball joints getting the knuckle assembly off, anyway.

The rim should not cause any problem - but you'll need different length spokes.

Rear hubs and front hubs are different widths, have different height hub flanges, and different amounts of "dish" (offset from the center of the hub body.

If your hubs and rims are in good shape; go ahead and re-use them; but you'll need help measuring or want to use a spoke calculator online for the correct length spokes.

I need to replace the tires and casters on my probasics wheelchair. I am not sure what I should order and whether the tires come on the wheels ot what.


As a general rule, it is best to replace the caster as a complete assembly consisting of tire and wheel hub. Usually this is the only way to replace casters when the tire is molded on to the wheel hub. It is the best way to replace the caster since you get a tire, wheel hub and 2 new bearings.
With regard to the drive wheels on a manual wheelchair you can get just a new tire. With a plastic mag wheel and hand-rim you can sometimes get just a replacement snap-on tire to replace the existing.(Snaps on like a rubber band using tire irons). If the hand-rim, wheel, spokes, and bearings are worn or broken, you are usually better off replacing the wheel assembly. With power chairs, it is more cost effective to only replace the drive tires and use the existing wheel rims. Hope this helps.

How do you disassemble bearings on the rear wheel to replace bent rim?


It sounds like you are trying to remove the hub, not disassemble bearings if you are trying to replace the rim. First off, replacing the rim requires you to rebuild the wheel, meaning re-lacing the spokes and truing the wheel. Unless you are very experinced in wheel building I sugguest you purchase a new rear wheel. Not only will it cost much less but it will save you much time and headache. Your local bike shop can help you with this. Hope this helps.

I need instructions on how to replace rear wheel bearings on my 1994 Honda Civic


Bearings are pressed into the hubs...much easier, faster and economical (if you don't have a press) to replace the complete bearing/hub assembly, no pressing is needed, since bearings are already pressed into the new hubs. Cost..aprox, 60 buxs each.
Here are the steps for the rear replacement...
Loosen the lug nuts on a rear wheel. 2) Chock the wheels and jack the rear of the car on the side with the lug nuts that you just loosened. 3) Remove the wheel by removing the lug nuts. 4) Pry open the dust cap covering the center of the axle/spindle. A small screwdriver tapped into the space between the hub and dust cap will work well for this. 5) With the dust cap now removed, use a thin center punch to straighten the little dent in the rim of the spindle nut so that you will be able to turn it freely in the next step. 6) Use a 32mm socket and a large breaker-bar to loosen the spindle nut. Unscrew the nut all the way and place it in a clean, safe area. 7) You should now be able to slide the hub/bearing assembly from the shaft. 8) Installation is the reverse of removal. Use plenty of high-temperature wheel bearing grease on all surfaces before you mount the replacement hub assembly.

IMPORTANT: Torque the spindle nut to 134 ft/lbs....(per manual specs)

When reinstalling the dust caps, tap them gently into place to avoid denting them...Install wheels, jack her down and pat yourself on the back...job complete.
Good luck..hope this will fixya up...please take time to leave me a fixya rateing...
