Home › Vehicles › Cadillac › Cadillac XTS Wheel Bearing Part Numbers
The short version
- The Cadillac XTS wheel bearing uses part number 513288 for 2013 through 2016, and for most of 2017.
- A 2017 XTS built with brake option J55 takes 515160 instead of 513288.
- 2018 and 2019 XTS bearings have no documented row in the catalogs; match the old part or the VIN.
- Front and rear catalog pages list the same numbers, so confirm position before ordering.
Cadillac held the XTS chassis steady for most of its run. The catalogs reflect that stability more than complexity. One number covers four model years, until a single option splits the line, then the trail runs out.
The XTS bearing at a glance
The default Cadillac XTS wheel bearing number for 2013 through 2016. It also covers 2017 cars built without the J55 brake package.
515160 replaces it only on 2017 cars with the J55 option code. Find the code on the build sheet or door jamb label.

Every model year this chart resolves: 2013, 2014, 2015, 2016 and 2017. On this chart a 2018 and 2019 Cadillac XTS is not documented, so those cars go by the old part or the VIN.

Lookups run through the cross reference page.
Cadillac did not split the 2017 XTS bearing by trim or drivetrain. It split it by the J55 brake option, a GM RPO code most owners have never heard of.
Order 513288 for the standard setup, and 515160 for a J55 car. Check the build sheet if the code is not obvious at the parts counter.
The XTS catalog rows for front and rear positions list identical part numbers, not separate ones. That reflects how the catalogs group the car. It does not mean one bearing serves both positions on a given install.
Confirm which position failed against the old part before ordering, since a wrong guess still costs a return trip.
Where the XTS bearing fits in the Cadillac lineup
The XTS shared its bearing hardware family with other full size Cadillac sedans of the era. Shoppers cross-shopping parts sometimes land on the CTS parts chart or the STS listings by mistake. All three names sound similar at a parts counter.
The SRX page covers Cadillac’s crossover of the same generation, built on a different platform with its own numbers. None of these substitute for the XTS row without confirming fitment first. The Cadillac model hub lists every sedan and crossover the catalogs track separately.
Duty and wear on a full size sedan
The XTS is a heavy, front-drive biased sedan. Its front bearings carry more load than the rear through corners and braking. A noise that changes with steering input usually points to the front, not the rear.
Prompt attention to torn CV boots helps the front bearings last, since a leaking boot lets grit reach the hub area. Salt belt cars see failures earlier than dry climate cars, a pattern common across the Cadillac range.
Diagnosing a Cadillac XTS wheel bearing
- Listen for load-sensitive noise. A worn Cadillac XTS wheel bearing usually hums or growls. The sound changes when weight shifts in a turn.
- Check for play at the wheel. With the car safely raised, grab the tire at 12 and 6 o’clock and rock it. Looseness points to the hub.
- Rule out the tires and CV joints. Uneven tire wear or a clicking sound on turns often gets blamed on the bearing. The real cause often sits elsewhere.
- Confirm the brake code before ordering. A 2017 XTS needs the J55 status checked against the build sheet, not guessed from the model year alone.
- Match the old part on undocumented years. For 2018 and 2019 cars, pull the failed unit’s number and cross reference it. Do not assume a nearby year’s part fits.
Common questions
What is the wheel bearing part number for a 2015 Cadillac XTS?
Every 2015 Cadillac XTS wheel bearing uses part number 513288, regardless of trim or drivetrain. That number holds steady through 2016 as well.
Does a 2017 Cadillac XTS use a different bearing?
Only if it carries the J55 brake option. Cars with J55 take 515160, and cars without it stay on 513288.
What bearing does a 2019 Cadillac XTS need?
The catalogs carry no documented row for 2018 or 2019. Match the old part or confirm by VIN rather than assuming continuity from 2017.
Is the front bearing the same part as the rear on an XTS?
The catalog pages list the same numbers at both positions, but that reflects how the rows are organized, not a guarantee. Confirm the failed position against the old part before ordering.
How do I find the J55 brake code on my XTS?
The RPO code list on the glovebox label or the original build sheet shows J55 if the car has the option. A dealer parts counter can also look it up by VIN.
