Where Timken axles fit today

Timken-Detroit axles were built into trucks for decades, and the axle business later became part of Rockwell, whose truck axle line is now Meritor. That history is why an old Timken carrier can share its layout with later Rockwell units, and why the numbers on the tag or housing are the first thing to check before you order. If your unit turns out to be a Rockwell or Meritor design, see rebuilt Rockwell differentials and rebuilt Meritor differentials for how to identify it.

One stop for old units

On an older Timken differential, the right replacement is often a matter of finding the right core or the right gear set. Tell us what is stamped on your unit and the ratio, and we will help you find it.
