Koyo Rear Wheel Bearings

[Trk90]

My new Timken's are packed in dry nitrogen gas (no grease) and says on the sealed plastic do not open until ,installed. ending this usage of packing grease forever...
last one I bought are dry nitrogen packed,
this is because the maker (savvy to the max) knows they their bearings failed in short time because the installer did not read the paper inside the box.
it said , this is packing grease to not run the bearing on any car with only packing grease
if you can see the grease there, the grease is 100% dead wrong to use.
easy no? open bearings of any kind for sure NOS , new  old stock with this silly grease inside?
closed bearings are ready to run./
each maker of bearing does their own thing here.  (but packing grease seen is no good)>> to drive 100k + miles , no good.
the bearing rust in be box (steel) unless packing grease or dry nitrogen or other inert gases are used,
what worst are no name bearings, from 12,000 miles away,

The original Koyo’s in my 1990 are exactly the same as the replacements minus the dust seal. The new seal has the same stamping as the original. The lubricant is Shell Alvania 2 according to the spec number given to me by the JTEKT rep. I believe it has been renamed Shell Gadus. Also, the bearings are prelubricated according to their 30-50% capacity.  I figure that the original bearings lasted 150k with both dust shields so why change it especially if I don’t know the reason.
