Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It fits inside the torque rod end and wears over time, causing clunking, loose steering, or uneven tire wear, so replacement is needed when play is detected. The bushing is a service part for Chalmers 800, 1023, 1030, 1040 truck series and the 700 trailer series. The exact part number TRM8644 was not found directly; the information is based on the similar part TRB8644.
