Inner Bearing

Post by **newbie** » Wed Oct 10, 2007 8:29 pm

Hiya, anyone know how to remove the inner bearing and oil seal from the front hub assembly..? thanks.

by using a drift, sometimes a socket of the correct size will do the job

and remeber that the thrust side of the new bearing goes to the inside, ie towards the hub

cheers., I've removed the outer bearing and the spacer and then I presume you remove the inner from the other side. I can't seem to get it through the seal..?

in the hub there is a couple of slots that u can use to tap the bearing and seal out
also remember to pack the hub hlaf full with grease and also the edges of the bearing when putting back

50 to 60 lb torque on the hub nut as well, do not torque back for split pin

thanks, I'm a tad worried of splitting the seal when I whack the bearing ring from the inside, does the seal come off, or is it bonded in any way to the sides..?

the bearings come out easier, there are 2 slots i think in the hub, do it from both slots, but you still may break the oil seal, i replaced the oil seal along with the bearings

thanks. If after cleaning and examining the bearings and they are alright, are they ok to go back in with the greese. warn bearings would be visibly worn wouldn't they..?

well now they are out i would say replace, there must have been a reason for wanting to take them out in the first place
for the sake of £18.00 i would say change them

ok, thanks. am I best replacing the inner and outer bearings or just the inner ones. mot said bearing feels rough when rotated and excessive play.

replace both inner and outer, as it does not take any lomger

what would be the reason why the bearings felt rough when rotated and excessive play. (one side totally had NO grease in there at all. could this have been the problem..?

yes they should be greased

If you are really stuck for a seal, the trick is to put a fairly wide flat-bladed screwdriver under it and give it a good sharp wack with the palm of your hand (lever-like)

Trying to ease it out slowly will only make it more certain that you scrap the seal!

Still seals arent THAT expensive and you get a set with the bearing kit anyway.

Absoposiloutley work grease into the new bearing (force grease into it with your fingers, then roll it against the palm of your hand .. repeat), and fill out the seal and space between with a healthy amount of grease, if you put too much in then it will just squidge out and fill up the cap, then ooze out the hole in the end, so dont worry about using too much!

Me being me, if I replace one side's bearings then I do the other at the same time, same goes for anything brake/suspension related ... but that's just me so...

Thanks very much guys for all your help.

Seals are dead cheap - must be replaced - that's why the bearing has failed - water and dirt have been getting in past the seal! Just bang them out and fit new with lots of grease.

It's not usual to fully pack the bearing with grease, it can cause overheating. There should be some air space. Don't forget to use High melting point grease.

Indeed - not 'full' of grease - but don't be sparse with it either!
