Rear bearings
How do you remove the rear sierra bearings from the carrier?

Remove and bin the oil seals.
Then remove the bearings.
It's then a case of driving out the bearing outer. You do this by taking a punch to the exposed 'lip' of the underside of the
bearing outer. Take care not to damage the inner surface of the hub that holds the bearing.
Then flip the hub over and remove the 2nd one.
To replace you need to drive the new bearing outer into place. Best would be with a press but I did it by placing the removed bearing outer on top of
the new and stategically 'bashing' it with a hammer!
Once it was partly in I could drive it home with the vice.
HTH,
James

hi guys
i remove them like so
1. remove seals
2. remove races ( now you are left with just the outer race )
3. with welder at high power weld all around the housing where the ball would normally run in the outer race
4. let it cool and it just drops out
hell of alot easier than pressing / punching out and probably less likely to miss with the hammer and wrap your knuckles, ( not that ive ever done
this of course )
hope this helps
regards
marc
p.s how do you add smilies etc to posts

I have done it marc's way, it works fine, I have done a variation on the theme, chuck it in a bucket of water just after welding, the race
cracks in about 5 places and falls out even easier
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

Is there away to remove the inner race, without the use of a welder as i havent got one. Cant drift it out with a chisel, thinking about taking it to
a garage for them to do, what sort of place would do it, and how much would they charge?

Why can't you drift it out?
I used a 6 or 7mm diameter punch. I'll admit it took me a while (on the first one) but it really was not one of the hardest things I've
had to work out how to do.
Just hit it with a firm but not excessive tap and keep working your way round- taking care not to damage the inner ring (do I mean flange?) as you
go.
I wasn't quite sure how the thing was constructed when I did mine and managed a couple of dings in the ring (oh sir!) but it was easy to polish
them out with a bit of emery.
HTH,
James

I just drifted them out with a piece of 12mm dia stainless bar cut off square at the end. Took about 10 minutes.

I used the stainless bar method (any steel bar will do so long as the end face is true) knock out the outer evenly to avoid wedging. Be careful not to
wack the inner carrier flange.
Piece of cake as they say.
Cheers
Dave.

The main thing is to use a relatively soft drift - that is something less hard than the bearing if you intend to re-use the bearing.
I use an old T-bar from a box spanner. Any drift which is hardened will potentially damage the bearing surfaces and depending on the type of bearing
this can drastically reduce life.
This is my 500th post!

I took out the outer bearings no problems, just drifted them out easy! im having the trouble with the inner races on the front bearings, havent looked
at the backs yet but they may be the same. You cant get behind it to knock it out because the face that holds the wheel studs is in the way. There is
not enough of an edge to get a bearing puller to hold on to it either.
