I don't know what type of bicycle you have, or how modern it is, but the handlebar and steering head are similar on most models. Try to remove the handlebars and steering head from the bike as a unit. There is a large nut at the top of the head tube (where the steering stem goes into). Loosen this nut, and the handlebars and steering stem should pull up and out of the bearing inner races. When you completely remove that nut, the headset will come apart... (including the fork and front tire which will drop out of the headset. If your brake and shifting cables are too short to let you pull the steering stem completely out of the steering head, you'll need to remove the handlebars from the steering stem. If you are careful, the bearing set, spacers and washer will stay on the fork tube when it comes out of the bicycle frame head, so you will know which order to reassemble them in. Either tag them or lay them in the proper order. Now you can clean the bearings or replace them.
It would be a good idea to clean the bearing races at the top and bottom of the steering head too.

Once everything is cleaned and ready to reassemble, grease the bearings and the bearing races and reassemble. When you tighten the stem nut down, make sure that there is no play between the steering head and the steering stem.

SOURCE: How to disassemble crank bearing on Schwinn Mesa Mountain Bike

You wil need a couple of special tools, or be fairly creative with the tools you have.

  1. remove the dustcovers in the crank arms at the crank axle
  2. loosen the crank retaining nut/bolt.
  3. thread in a chank puller and pull the crank arms.
  4. remove the lock ring on the adjustable side of the crank axle (Requires lock ring wrench)
  5. remove adjustable bearing cup.
  6. remove axle and bearings
  7. replace or repair as needed.
Once you have it opened up ou can determine if you need new bearings or crank axle.
to assemble, reverse above procedure, insuring bearing play is minimalized.

Hope this helps.
Ed

This isn't Bike Repair 101-level stuff. Take it to a reputable bike shop and have them teach you while they do it. If they're cartridge bearings it's fairly simple. Next time, you can handle it. Be advised, crankset removal tools are specialized and expensive for the casual bike owner who would use them only once every few years..

SOURCE: Ball bearings fell out of handlebar connection on 3-speed bike.

Take it to a professional bike shop. They have the knowledge and tools to set it right.

Or take a look at this:
http://www.sheldonbrown.com/headsets.html

The headset nuts were not necessary to be moved for handlebar adjustment. Now the bearing load is too tight. Correct adjustment of the headset requires a delicate balance between tightness and freedom of movement. If your bike has/had the original bearings it's a safe bet they may be due for replacement anyway.

Bad sway bar


Could be CV Shaft or Hub Bearing as well. Jack up the front of the car, support with Jack Stands and check for play in wheels/hubs/bearings/linkage by grabbing wheel at 3 and 9 o'clock positions for tie rod ends and steering linkage, then 12 and 6 o'clock positions for bearings. You should barely be able to feel play. If you think it is more than acceptable climb under the car while someone else performs the tasks above. Turn wheels for excessive brake noise or out of tolerance discs. Out of tolerance discs will cause premature brake wear and cause pads to move around in the caliper sometimes before starting to grind. Finally, and what I think you're hearing/feeling is the CV Shaft. Grab shaft, move around feeling for excessive play in joint or splines on each end. Turn steering all the way lock to lock and turn wheels at each lock, forward and backward, feel/listen for clicking/popping. Most of the time you can quickly easily diagnose bad CV Joints in a parking lot by slowly, safely driving in a circle forwards and backwards making the joint noise more pronounced. If it is a CV Joint, my advice would be to spend the extra few bucks and replace the whole shaft while you're there. Its quicker and easier requiring less specialty tools to complete the job.

How to tighten steering head bearings on a 1999 yamaha r1


HI, CARRY OUT THE CHECK BELOW BEFORE YOU START ADDJUSTING YOUR STEERING.
place the machine on a stand, suport the front of the machine so you can turn the steering freely from lock to lock and geting a feel for how tight the bearing is before adjusting or even undoing the top nut, grasp the forks at the bottom as you kneel in front of the machine pulling on the forks at the lowest point to feel for free play, normaly detect by a small amount of movment,or a clicking noise



tightening the steering head bearing on any bike is not difficult, but it does require some level of skill, undo the top nut on the centre of the yoke, below that you will see 2 castleated nuts some models have a locking tab between them so you cant turn 1 without first undoing the other, in this case it is best to remove the top yoke, once you can turn the nuts under the yoke you simply turn clockwise to tighten and anti to slacken,

there is a fine line between tight and slack, a bearing which has been left in a loose state for a prolonged period may require replacing, as so 1 that feels rough or notchy,

in some cases only a small amount of tightening is required, remeber when the top yoke is replaced and tightened this will put more tension on the bearing, so a bearing that feels tight without the top nut tightened will be overtight when yoke centre nut has been tightened, method of satifaction is when the top nut is tight with the steering clear of the ground in a straight ahead position the handlebars must fall from centre left, right with no friction detected, again checking the movment by pulling on the fork lowers.

OVERTIGHT BEARING WILL AFECT THE STABILITY OF THE MACHINE.

What is the torque spec. for steering head, and what is the cause of loosening


Bearings break in and wear down over time. A good mechanic will adjust the steering stem bearings during the 600 mile check up. Make sure the bearings have grease. Snug up the nut so it is firm and reasonably tight (you do not want the bearings to bind) . If the steering is starting to bind back off till it turns smoothly. Hint : It is easier to feel firmness or binding if the wheel is off the ground when turning the bars.When there is a fine thread nut involved I do not think it is safe to use a torque wrench. Hand snugging can be enough to bind the system. Double check the feel after you put the wheel back down , you may have to tighten just a touch.

The right front tire make a whining sound and when the steering wheel is turned to the left it gets louder.


Sounds like you have a bad wheel bearing. Sometimes you can jack up the wheel, in your case the right front) and with one hand spin the wheel while holding onto the front strut spring with the other. If you can feel the noise (sounds wierd but you can feel the noise) than the bearing is bad. It helps if the transmission is in neutral (make sure you secure the vehicle from moving while its in neutral)

Front crank sprocket clicking on bycycle, when I pedal the front crank sprocket clicks, it isn't the pedals.


make sure all sprocket bolts are tight.
check chain to make sure you have all rollers between links are there.this can make a clicking noise or skip teeth if one is missing when you pedal.
if you feel clicking in the pedals (even if you think it isnt the pedals),then it could be your bottom bracket bearing gone.
put one pedal towards the floor and stand on it.did it click?then try the other pedal.if you got it to click then your bottom bracket is loose

My GMC Yukon XL is making a cranky/rusty noise


If it sounds like the font end of the truck is going to break apart beneath you then the steering shaft is to blame. There was "bulletin" given GMC dealers I believe in 2003 or 2004 stating that the steering shaft would need to be replaced to correct the issue and only if the customer complained of the noise would they replace the shaft. Then they changed the solution from replacing the shaft to lubing the shaft which was a very temporary fix and the noise would soon return. Then they went back to replacing the shafts. My point is there is no cure but replacing it is your best bet and it will make your tuck feel brand new. Unfortunately it may go out again but there is no physical damage from the defected part that will cause you to lose control. If that were the case, GM would have issued recalls, not bulletins.

2007 Dodge Magnum, RT/AWD - Front Driver side wheel area noise, like snow/ice was caught up under, checked notheing. One month later the noise came back but with a vengence. Now makes the noise at all...


Check the Brakes first. Are the pads worn down to metal. Is the Caliper Stuck (open)?
Raise and Support the Front and Rear (because of AWD) of the vehicle.
Remove the left front tire. Make sure the Parking Brake is engaged. Place the lug nuts back on the lug studs. Place the Vehicle in Neutral. Turn the wheel (without the tire on) and listen for where the noise is coming from. A bad bearing will feel rough (not smooth) and sound 'crackly' when trying to turn the one wheel. Make sure it is not from the CVJ.
If not smooth: Remove and Replace the wheel bearing. And yes you can do it yourself saving you about $150-$200 dollars. It is a bolt-on (4 bolts) bearing. Bolt Heads should be on the back side of the steering knuckle.
Remove the Brake Caliper, Caliper Brace, and Rotor.
Remove the 4-bolts (turn the wheels left and right to better access these bolt heads) and slip the bearing off the Axle. You may have to hit the bearing to loosen it.
