Do All Four Wheels Have Tie Rods?
No. Front wheels almost always have tie rods — every rack-and-pinion or recirculating-ball steering system uses them to turn the front wheels.
Is a Tie Rod the Same Thing as a Stabilizer/Sway Bar?
No — they’re different parts in different systems, even though they look alike and fail in similar-sounding ways. A tie rod is part of your steering system.
