Greetings. It may be of interest to all on the net that new replacement 
bearings are not of the same quality as originals. Most of the bearing 
manufacturers have moved production or been bought by off shore firms. I 
have replaced trans bearings recently that have had slightly different 
dimensions-shims have had to be added or removed. A recent replacement of 
the rear hubs-sealed units-on my Mazda revealed that one hub  was defective 
from the box and that another was slightly noisy. A friend who ran a TR6 
club and rebuilt many transmissions alerted me to the changes in bearing 
manufacture. His advice was if the bearing looks useable and is not noisy 
leave it alone. He had replaced trans bearings several times to find that 
there was less noise prior to the replacement. I hope this is of help to 
your decisions and not confusion.
