Hi ya'll, Is replacing wheel bearings on an Across a big/dificult job? The manual describes the need for 'special tools' (ooohhh). I've ordered the bearings from Pyramid Parts (ludicrously low price so I got both front and rear). Their sale ends Friday btw. Reason being I reckon my front bearings need replacing - there's a constant whine coming from the front wheel - it's really noticable when I pull in the clutch and coast at about 70-100 km/hr - it sounds like wheel bearing noise is a car but much more constant. It doesn't sound 'right'. I could easily be completely wrong about the noise, but figured I'd grab the bearings while Pyramid have their specials happening. There's no noticable wobble in the front wheel, but my old-man suggested lifting the front and spinning the wheel with a stethescope (which I own one thereof) against the axel and listen for scraping noises etc. So, any tips? :icon_rr: (don't really know why I put the afro dude there)
You will probably need a press to pop the old ones out and then press the new ones in. If the old ones just fall out then u know they are cactus. Good luck mate. Len
I have done them before and its not a huge job, however the challenge is getting the front of the bike off the ground to remove the wheel to access the bearings, I have some paddock stands that I use. If you have a trolley jack, you will be able to raise the rear wheel off the ground to remove the wheel. To remove the old bearings, I have used a round bar and a hammer to punch the old ones out, then a simlar process putting them back in. Happy to have a chat with you before you start :Thumbs_up: Cheers Chris
Hmmm - I might give you a buzz about it Chris (PM me your number if that's cool?). I'll see what the local repairer will do it for in the meantime.
:Thumbs_up Hey Brad Grab the front wheel and try moving it from side to side, if you detect any movement the bearings are cactus. Same applies to the rear. No special tool required, a good solid hammer will be fine. Tap the bearings out on one side then flip the wheel over and do the same again. Watch how the bearings come out and you'll have no problems. Most bearings today are pre:lubed so all you have to do is knock them back in. Good luck with it. Phil
A mere hour with the mechanic chaps - I think I'll be lazy and get the pro's to do it... :icon_rr: - There's that afro dude again!
Replacing the wheel bearings is a easy job. Just make sure you drive it back in on the outside edge of the bearings. You can get special tools but not necessary unless you plan on doing a lot of them. As for if they need replacing movement side to side in the wheel and or noise when they are spinning is a sure sign they are not healthy. They are not a expensive part so if there is any doubt change them anyway. If you wash your bike with a pressure washer spraying the bearing area directly can wash the grease out of them I have been told.
When i did mine i just hit the aluiminium around the hub with a paint stripper gun for a few minutes and the bearing basically fell out on its own, no drift required. Same for the reinstallation, didnt need a drift to seat them back in either
If you are heating the wheel hub also put the bearings in a freezer overnight they will shrink slightly and the wheel will expand when heated and fall into place.
