Rhino Wheel Bearings

Big R. no reason for a press. Knock each one out from the opposite side it is on, or from that bearings back side. Once you get both out, use one of the old bearing races or the right size socket to knock the new ones in. Not that hard once you have done a set. I got lots of practice doing mine.

Man I can't get them out. I have tried. I just can't get enough bite to bang that f$%#er out Will a slide hammer bearing remover work????

Dude.....a punch and a hammer.. TKOB ,take care of business...............

take a old med flat blade screw driver and grind the end down like a dull knife blade.its a lot easier than a punch.once u get it moving its done.

A good punch will work (slowly)but a cheap punch will chip.

Well, I have finally banged out my bearings. In doing so I have figured out a few things. One do not let your dealer ever install your bearings. They will NOT do a good job. Two, buy yourself a blind bearing puller set. You will not use the slide hammer but the puller sure comes in handy. Three, pack those bearings full of grease. They do not come with much in them at all.....

Water, sand and mud is the down fall of your bearings. Check this out.


Now you need to buy one of these. $42.00 at harbor freight..


Leave every thing in the box except in big puller. Get it out, set it in the bearing flip the spindle over and start banging. about five wackes and they're out.




Pull the seal in your bearings and look what you will find........ nothing!!!!!


Get some of this and pack and cover every thing inside that spindle ..... And it might hold up for a while.....

I have wondered why wheel bearings should be packed to 1/3 of capacity. Here are some answers around the Inet.

I sell bearings for a living....the LU is NTN's suffix for rubber sealed bearings and the RS stands for rubber seal as well. When a bearing is manufactured it is filled with a pre-determined amount of gease that is good for the LIFE of the bearing. For all you who seem to think overpacking these brgs with grease is going to work for you...all I say is good luck. All you doing is creating alot of excessive heat and drag as the rolling elements (brg balls) are skiding in the raceways not turning thus causing more premature failure. If your that hard up my next advice is to buy new ones even offshore make from a BEARING DISTRIBUTOR for a couple bucks is better than what you are doing by damaging the seal, overpacking etc and save your time and effort!

Roller bearings should be "packed" with grease to 1/3 the surface area. More than that amount will cause skidding of the balls to the race. The good news is that on the 6205, the seal allows an over packed bearing to release the excess grease and, because of the excessive lube, keep the water out causing it to live longer.

With these explanations my understanding is over packing causes the excess grease to "trap heat", and the actual balls in the bearings to "skid" or not turn, all the time, as intended. I would say that causes wear on the race and tiny flat spots on the balls. I have always thought more is better when packing or re-packing bearings.....guess I was wrong.

That said, there are comments that say over packing is better, but the 1/3 capacity comments far out number the over packing comments.

Well damn, I bet you I am over packed. I filled the bearing and spindle with as much grease as a could. I mainly did this to keep water out. There was a lot of room in the bearings for water to stay causing rust. I think I would want heat over rust.

If you ride cold weather over packing is also bad because it will freeze to an extent and not let the bearings work freely.
I was told by the company that installed my over head doors not to put grease on the rollers because of this, they said the grease would freeze not allowing the rollers function properly and cause premature failure.

It would have to be very cold to freeze grease.

Well, I have tried it their way and it did not last very long. So now I will try it my way. I don't think those bearings are turning real fast the way I ride.

I just changed a set in my drivers side rear. I did put extra grease in them. I have a set for the other side. I will go ahead and change them to the new ones with the factory grease only. I will keep you all updated on what seems to be working better and get some pics.

I am putting mine together and I think I will be need some ball joints soon

I don't know if the grease actually freezes but it gets very solid causing the bearing not to roll properly and wear out faster. At-least that is what they told me on the door rollers, they said to use regular motor oil a couple times a year.

Any updates yet? I'm needing to change the rears again ( last set was AllBalls and lasted about 500 miles)

Nothing yet dmac. Bought a RZR S and haven't been riding the Rhino. So it may take a while to get good results.

Put in AllBalls rear bearings yesterday. I put some extra grease in there, but did not cram them completely full. I did use some anti-seize on the housing when I put the bearings in. MKing says that helps to get them out the next time. Big-R was right.....blind bearing puller worked like a charm.

Very cool. It is the easiest way I could find (other then a press) to get them out. I am glad it worked out for you.

Thanks for the tip. I can't wait to get it back on the trails.

I put alls balls in my rear spindles today. Front tomorrow. I did add some grease to the bearings. One bearing had only enough to barely coat the balls. They also sent me the wrong seals for one rear set.

3 of 4 had a good amount of grease. 1 barely had any.

Ordered mine today. Hopefully it will be a while before I need it..

Replaced my rear bearing again today... I didn't get but a couple hundred miles out of the AllBalls bearings and they looked worse than the stock bearings did at 1400miles...

FYI I replaced the right side with Moose bearing which looked identical to the AllBalls bearings and had the exact same numbers on the bearing...

I replaced the driver side with bearing from a machine shop to see how they do....

Did you get to use the blind bearing puller?

3206 miles......still on stock set! There is no movement AT ALL in any of them.
