Looked for a Timken cross referenced bearing, but no luck.

BUT, I do find a Dodge bearing that MAY be an equivalent bearing, same size and description in ASA as well. Part number is: MR453231. Online search shows $30 for the part. Might want to call a few Dodge dealers in the area to see if they might have the part in stock, and if they can confirm compatibility.
