I fitted some new bearings to my Sierra hubs. Basically I stripped and and cleaned the old units.

Dropped the new inner races with the tapers facing outwards. Oil seal onto the drive flange, then the bearing onto te stub and placed that into the carrier.

Then from the other side taped the other bearing over the stub shaft. Put the large washer on and then the nut.

When just tightend by hand though the drive flange is very very difficult to turn. I have done the other side in the same way and have the same problem

Any ideas whats going on. Wrong bearings? wrong method?

Are your Drivshafts lobro or Push in ?

If they are lobro have they had the ABS teath removed ? on some of the rear uprights they need these teath machining off or they catch on the upright.

Sorry, meant to say this is for the front bearings.

They are very tight till you run the car on them then they loosen up. Tighten them to the torque setting and put the wheels back on. They are not like taper bearings in Cortina hubs which need to be free turning.

I think they are taper ones in there.

I placed them so the tapers are facing in opposite ways too. I'm pretty sure thats the way they came out.

That is only the outer race, the stub axle is not tapered. Follow the instructions in the manual and tighten them up, hub nut 229 to 258 lb/ft or VFT with the big bar at which point you will usually not be able to turn them by hand at all without the added leverage of the wheel.

Mine were extremely tight after fitting them using correct method. After a few miles they bed in great. It just worrying when you can hardly turn the hubs at first. From what you describe - nowt to worry about.

Thanks for the replies guys, saved me buying new bearings only to have the same problem and saved me buying brand new hubs lol.

Will wait and see and cross my fingers.

they're always tight at first as pete says, drive it 100 miles and check again, should be free then.
