Order your tie rods from Masterparts.
As its name suggests, the tie rod ties together your steering rack and your steering knuckle (the part your wheel is attached to).
Most cars have an inner tie rod and an outer tie rod on each side of the vehicle so that the linkage has two pivot points.
The tie rod can be permanently lubricated or it may have a grease zerk for periodic lubrication.
Regardless of which kind you have, the tie rod will fail eventually, resulting in loose steering.
Noises, wandering and overall poor handling are signs of a tie rod that needs replacement.
