PROBLEM
Show/hide table
| The 257-8660 Thrust Bearing can fail on certain CX31 On-Highway Transmissions. The axial thrust load on the thrust bearing can be too high. Insufficient clearance can result due to the stack up tolerances of mating parts. The overall clearance has been increased by designing a new 3577145/">357-7145 Carrier Assembly. |
