GMB Tie-Rod End

GMB tie-rod end assures proper friction and pivoting action to enable smooth vehicle handling. It properly responds to road conditions in order to ensure stable driving and to support driving comfort.
In order to realize these goals, GMB utilizes high-friction resistent resin(POM:ACETAL), special synthetic grease to minimize friction. Inside dust cover a mud-preventive grease is contained to maximize ball joint life.
Thai GMB conducts static tests, destruction and endurance tests upon development to ensure product quality.
Proper heat treatment on special steel, rigorous receiving inspection, and QA patrol in addition to self check in quality control enable us to ensure the driving comfort and safety.

Functions of Tie-Rod End

Transfers steering force from steering wheel to running wheel and at the same time absorbs road bumps and shocks as well as vibration in order to maintain handling stability. Running wheel side of tie-rod end is constructed with ball joint to respond to road bumps (vertical shocks) and to wheel turns (horizontal movement). The other end has a thread for connecting rod or rack end. By turning the connecting rod or rack end toe-in is adjusted as one of wheel alignments.

By vehicle design the thread may be male of female to connect the next tie-rod end.

The other side of plug is filled with mud water prevention grease inside dust cover to prevent leakage.
