This table covers the steering gear assemblies that turn the tie rods. Typical signs include fluid at a torn boot, a growl when you turn, or play that the inner tie rods do not explain. Flush the old power-steering fluid with the rack — grit in the old fluid is the usual cause of a repeat leak.

Buying Steering Parts for a 2018 Cadillac CTS

On this vehicle, the steering system connects driver to road through the rack, pump, tie rods, and column components.

  • Match the engine first. Every steering part here is engine-specific; each row shows which engine(s) it fits.
  • Read the notes on each row for position, trim and spec qualifiers before you order.
  • Where labor overlaps, replace the inner and outer tie-rod ends together on higher-mileage vehicles, then get an alignment.
  • Cross-reference the manufacturer part number against your old part or a service-manual listing.

Start with the largest groups on this page: Tie Rod End and Steering Shaft .

Frequently Asked Questions

How many steering parts fit the 2018 Cadillac CTS?

Our catalog currently lists 73 steering parts for the 2018 Cadillac CTS across 17 subcategories and 10 brands, covering all 4 engine options (2.0L L4 Turbocharged, 3.6L V6, 3.6L V6 Turbocharged and 6.2L V8 Supercharged). Each part is matched to the engine(s) it fits.

Do steering parts differ between 2018 Cadillac CTS engines?

Yes. Every steering part on this page is engine-specific. Each row shows which engine(s) it fits — use the filter at the top to hide the rest. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.

What are the signs of steering problems on a 2018 Cadillac CTS?

Common symptoms include play or looseness on center, a whine when turning, fluid weeping from rack boots, or uneven tire wear on the front axle. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.

What should I replace at the same time?

Where labor overlaps, replace the inner and outer tie-rod ends together on higher-mileage vehicles, then get an alignment.

What do the market flags (US, CA, MX) on each part mean?

They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2018 Cadillac CTS was originally sold in the US, the safest choice is a part marked for the US market.

How do I make sure a part fits my 2018 Cadillac CTS?

First match the engine — each row shows which engine(s) the part fits. Then flush old power-steering fluid when replacing a pump or rack — grit in the old fluid is the number-one cause of repeat failure. The notes column carries position and trim qualifiers where they apply.
