Vitesse front Hub Bearing Spinning

[MarkB]

Hi
Bought some S/H front uprights with hubs and discs a few months ago for the Vitesse. Just got around to pulling them apart and unfortunately the inner bearing is spinning in the hub on both of them. I have heard this can happen but never seen it on the numerous cars I have owned. Looks like I bought scrap? just thought I would check before I bin them that there is no way around this ie. fitting slightly larger bearings? I don't suppose this is possible but I thought I would ask


Cheers

Try some Loctite Bearing Lock. It's a high strength adhesive similar to Tread Lock.

An old trick is to use a punch and hammer around the circumference on the upright where the bearing will sit, raises a few thou in locations around the circle and allows the race to grip tight.

Both suggestions make good sense, but I wonder if it might also be prudent to first replace the bearings and races with new?

the bearing would not wear the softer casing would go first try the other methods explained thats why you asked the question

Thanks for the ideas, i will fit new bearings, which may take up some of the wear. These were bought as spares for machining as I am experimenting with vented discs and not happy with using spacers to to try and overcome various clearance issues. I think a combinaton of punch and locktite suggested by Timraven and Spider should work.

Thanks

I would buy new bearing's and races first.  If they still spun, after test fit. I would then buy new hubs and or spindles.  Easy to change out.  

Hint: IF you can go to the supplyer I would try the fit before I bought the hubs/spindle.

As you know it is never a good idea to put new bearing's in old races.

If not too far gone (ie no discernible "slop") then bearing fit might be an acceptable bodge (in fact this is the assembly method of choice for certain helicopter makers, although the tolerances are VERY tightly controlled and they do probably use some fairly special loctite!)

However, the centre punch trick is a plain bodge in this context and I wouldn't it allow on my car.  Using your undamaged parts seems like the best route!

Both the inner races are  supposed to rotate on the stub axle, look at the back of the D washer you will see the light polishing caused by the gentle rotation , look at the stub you will see the same burnished rotational  marks. this is correct and quite normal practice,
if they were a tight fit on the stub  you would not be able to remove the hub by hand and  you effectively destroy the important need for the 0.002"/0.008" endfloat .
