Will These Balls Suit My Deore Xt Rear Hub?

Ref Shimano 5/32" balls

Unfortunately these will not be the correct replacement bearings for your XT hub. You'll need to check the age of your hub as some of the very old ones use 1/4" balls wheres as most of the current ones use 3/16" balls.

Shimano Bearing Compatibility

I need some 5/32" bearings for my Shimano Ultegra WH-R600-R rear wheel but the parts are out of stock (SJS part # 32684, Shimano part # Y4BR98130).

You have some Shimano Deore XT WH-M778-F bearings of the same size in stock (SJS part # 32691, Shimano part # Y4FE98030).

Is there any reason why I couldn't fit the XT bearings to my Ultegra hub? Are they a different material or grade that would not be recommended?

These bearings can be fitted instead, they will be a grade below what you currently have fitted but they are still high quality bearings.
