Q:How do i change the wheel bearings on a four-wheel drive 96 jeep grand cherokee?

pull the wheels first, then you will have to remove the caps on the axles ( front ones ) , there is a tool to remove the nut that holds the wheel bearings in place , you have to remove that, the brake calipers and rotors will have to come off too, the rotor has the wheel bearings inside of it, the outter and inner, , use new bearings -they usually are under 30 bucks for the front bearings, and about the same for the rear bearings, the rear bearings are on the drive axle, so you will have to pull the axles to have the rear bearings removed, and they are pressed on, so you will need to take them to a shop with a press for r/r of the wheel bearings

Q:two of my bearings are slightly dented. What can I do? I just bought new bearings and I had to change them because I bought new wheels. :?

If your bearings are dented, there is nothing that can be done about it. Either suffer with the wiggling until the bearings fail, or replace them.

Q:i have two different sets of bearings but some of them are messed up so i was wondering if i can put mix them up and put them in my board

Yeah okorder

Q:It is a rally sport with the 3.8 v6 series 2

You can certainly do the majority of the labor and parts replacement. Any machine work to the crank shaft or connecting rods as well as any balancing that is needed will have to be farmed out to a shop that has the equipment needed to do that type of work.

Q:I have Bones Reds skateboard bearings and usually just spray WD40 on/in/around them and spin them a little and then spray again and let it dry before putting them back into my wheels and then spraying them again with WD40. Is there a proper way to deep clean/lube them? Also, any instructions on how to remove the shields (because its only one-sided red). Thanks!

I actually just lubed my bearings yesterdday. Don't use Wd-40 it may seem better but it attracts more dirt than it would normally. Since you have Bones get Bones Speed Cream RF. Bones also make cleaning easy for there is only one shield that needs to be taken off which is the red shield. To take them of just get a thumb tack and go in the gap between the metal and the shield and put it in and pry it off. It will then snap back in after cleaning. Also when you buy Speed Cream it gives you all the instructions.

Q:im getting a evo longboard and i have a stella a form and i want to know if i have to clean my bearings and when should i do it and where do i get them

You should clean your bearings about every month or couple months, or after you have ridden in the sand or water. When you clean you bearings you take off the rubber/metal seal on the bearing. You then place them in Acetone or High % Rubbing Alcohol and shake them around to loosen the dirt. After, you quickly dry them with paper or a towel. Once they are completely dry, you lube them with Bones Lube, White Lithium Grease, or Sewing Machine oil. DO NOT USE WD-40! Then put the rubber seals back on and you are done. Check out tutorials on youtube to get a better understanding.

Q:I am interested in cleaning my roller blade bearings so that are free of sand.I saw a recommended video to wash the open ball bearings in acetone but I need some help understanding how to get my bearings to run their best.I found some nail polish remover and I am planning to wash the bearings in a small bath unless anyone knows if a more pure formula of acetone might be safer.I'm still doing some research and I found some chemists on the internet mentioned balancing the alcohol to water ratio 1:1 with acetone sort of like with mouth washthey also mentioned that methyl acetate and how it might help to filter it out. I'm wondering I'm now interested in seeing how acetone might react with sand (SiO2) but I'm actually thinking it might just dissolve it.What does everyone else think?Is there a better way to clean bearings? (excluding lube)

Absolutely none of the liquids you mention will react with SiO2 or dissolve it. There is nothing that will dissolve SiO2 that won't also dissolve your bearings. The point of the various bits of advice is that the acetone (or whatever organic solvent) will dissolve the lubricant in the bearings which is holding the sand grains there. Whether you use nail polish remover, or acetone (diluted or not) or gasoline or kerosene or maybe even alcohol doesn't much matter. (Although in all cases you need to observe the safety precautions about inhalation and fire hazards, and keep the solvent off of the upper parts of your roller blades.) Your goal is to remove all the oil (or whatever lubricates your bearings) then let the bearings dry completely. Then you should be able to remove any left over sand by brushing it out of the bearings with something like a soft brush or blowing it out with compressed air. After all the sand is removed, you need to re-lubricate your bearings. (I've been assuming all along that your bearings are metal. If they are not, you need to be careful about your choice of solvents, lest you dissolve your bearing too.) I doubt there is anything else you can do to remove sand from your bearings. In the long run it's probably easier to find a place to roller blade where there isn't so much sand.

Q:Give a detailed procedure of maintenance of electric motor bearings and the effects of overgreasing?

Motor manufacturers have recommendations which are specific to the device and service category (ambient temperature, load, duty cycle, air quality, dust, particulates, etc.). These vary for journal, roller, and radial ball bearings. In the case of electric motor bearings; cleanliness and free air circulation for cooling are critical. Ball bearing are generally sealed or shielded, and permanently greased. In cases where they are being restored as they approach the end of design basis service life; they can be cleaned in an oil bath (not to exceed 100C), rinsed in solvent, and regreased to ?-? of the free volume. Excess grease is universally regarded as destructive. Over greasing is said by motor manufacturers to create overheating which boils off volatiles and changes the properties of the grease. The vapors from condensation deposit nearby trapping dust, blocking air flow, and exacerbating overheating. Lubricant manufacturers cite degradation of lubricant due to shear.

Q:Im getting bones reds bearings for christmas and i would like to know the kind of difference i will see with them compared to the stock bearings that came with my longboard. Also, should i be worried about lubricating them or will they be fine without it?

So what are some goodlong boardd wheels, bearings, trucks, and decks if I want to go fast? and what durometer for the wheels? I was thinking about getting abec 11 gumballs like 81A. Bones swiss or redz bearings. Are these any good for speed?
