On a 2nd gen, the part numbers were a bit odd. Timken didn't show a direct cross over from the original Japanese brand (NTN or Koyo - don't recall which). If you are able to find a Timken brg for this, it won't have the seal.
All Balls is a brg repackager. They don't make anything (that I know of). If the tapered bearing brand is one of the 1st world producers (Japan - NTN, Koyo, NSK; Sweden - SKF, Germany - FAG) you will be alright. However, if it turns out to be one of the Chinese manufacturers (Peer), I would pass.
In a younger life I was an engineer for Timken. Top quality. However, the steering application isn't very taxing to the bearing design. Therefore, any good quality bearing will work.
Just keep in mind you need the seal with it.
FYI - I bought bearings from the dealer when I replaced mine.
