- Summary
- On certain heavy duty trucks built with sisu FR2P-21, sisu FR2P-26, sisu FR3P-33, or sisu FR3P-48 rear axles, a counter-bore machined in both ends of the worm wheel opening of the slack adjuster housing reduces material thickness between the worm wheel opening and the worm shaft opening. Under normal service a crack may develop in this area rendering the slack adjuster inoperable and reducing brake effectiveness.
- Consequence
- Reduced vehicle braking could lead to a crash.
- Remedy
- Dealers will inspect the slack adjusters, and replace the adjuster if found defective. The recall began on July 31, 2008. Owners may contact freightliner at 1-800-547-0712.

Has your Western Star been repaired?
Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.
NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Western Star dealer can also check your VIN. Recall repairs are free.
