The short version
- A 1990 Chevy Silverado front wheel bearing replacement depends on suspension package: 515001 heavy duty, 515002 light duty.
- From 1992 to 1994 every 4×4 front uses one number, 515001, no matter the suspension.
- 2WD trucks stay serviceable: SET5 on heavy duty brakes, SET6 on light duty brakes, both with outer SET3.
- The rear axle bearing is 513067 on the 8.5 inch ring gear, R-1561-TV on the 9.5 inch.
This page covers the 1988 to 1994 Chevy Silverado. A 1990 Chevy Silverado front wheel bearing replacement starts with the suspension package on 4×4 trucks. Heavy duty and light duty suspension trucks took different hub numbers through 1991.
The core numbers for this truck
515002 only applies to light duty suspension 4×4 trucks built from 1988 to 1991.
On a 2WD truck, a 1990 Chevy Silverado front wheel bearing replacement runs through a tapered set instead. SET5 or SET6 applies depending on brake package.

This page covers the 1988-1994 Chevy Silverado: 1988, 1989, 1990, 1991, 1992, 1993, 1994. Other years live on the main Chevy Silverado wheel bearing page.
On these C/K pickups, Silverado named a trim package, not a separate model line. A parts counter may file these numbers under C1500 or K1500 instead of Silverado.
On 1988 to 1991 trucks the suspension package decides the 4×4 hub, so check that before ordering.
Year by year
1988 through 1991 splits the 4×4 front by suspension package: 515001 heavy duty, 515002 light duty. 2WD front numbers only start appearing in the catalogs from 1990.
1992 through 1994 simplifies the 4×4 front to one number, 515001, regardless of suspension. 2WD trucks continue on SET5 for heavy duty brakes through 1994.
The light duty 2WD brake row stops at 1991. Later light duty 2WD trucks mean matching the old part or the VIN.
1988 and 1989 2WD trucks fall before the documented front rows. The catalogs we hold start 2WD coverage at 1990. Those two years also mean matching the old part or the VIN.
Where this generation sits
This page covers the oldest of three Silverado generations here. It answers a 1990 Chevy Silverado front wheel bearing replacement question directly. Later trucks, 1995 to 1998, use different numbers on the 1995 to 1998 page.
Rear axle choice runs on ring gear size the whole time, not year. The 2WD tapered sets can be repacked rather than swapped outright, see repacking a wheel bearing. Getting the preload right matters just as much as the number, covered on preload and end play.
Diagnosing a Chevy Silverado wheel bearing
- Identify the drive type first. A 4×4 truck uses a hub assembly. A 2WD truck uses a serviceable tapered set, covered on drive type and wheel bearings.
- Listen for a rhythmic hum. A worn bearing changes pitch with road speed and gets louder over miles.
- Rock the wheel at 12 and 6. Play in that direction points at the wheel bearing rather than a tie rod.
- Check the suspension package on 4×4 trucks. Heavy duty and light duty trucks from 1988 to 1991 do not share a hub number.
- Confirm brake package on 2WD trucks. SET5 and SET6 are not interchangeable even though both pair with outer SET3.
Common questions
What wheel bearing does a 1990 Chevy Silverado use?
A 1990 4×4 with heavy duty suspension uses 515001, and light duty suspension uses 515002. A 1990 2WD truck uses SET5 with heavy duty brakes or SET6 with light duty brakes. Both pair with outer SET3.
What wheel bearing does a 1994 Chevy Silverado use?
A 1994 4×4 truck of any suspension package uses 515001. A 1994 2WD truck with heavy duty brakes uses SET5 and SET3. Light duty brakes that year mean matching the old part or the VIN.
How do I tell heavy duty from light duty suspension on an 88 to 91 truck?
The suspension package is usually listed on the door sticker or build sheet. A parts counter can confirm it against the VIN. A 1990 Chevy Silverado front wheel bearing replacement should not proceed until that package is confirmed.
Why does the parts desk sometimes call this truck a C1500 or K1500?
Silverado was a trim level on these trucks, not a separate model. The base model designation was C1500 for 2WD or K1500 for 4×4. Either name should point to the same rows on this page.
Is the rear bearing the same as the front?
No. The rear sits behind the axle seal and is an axle bearing, not a wheel bearing. See the details on the axle bearing versus wheel bearing page.
