DJB Front Wheel Hub & Bearing Assembly for 1999–2006 GM 6-Lug Vehicles — Pair, ABS-Ready, Pre-Lubricated

If your Silverado, Sierra, Tahoe, Yukon, Escalade or Suburban is showing wheel noise, vibration, or ABS warnings, the DJB 515054 hub and bearing kit provides an OE-style replacement built for straightforward installation and long service life. This kit includes two front assemblies (left and right), is designed for 6-lug wheels with ABS, and comes pre-sealed and pre-lubricated to reduce installation time and avoid bearing contamination.

Which vehicles and axle positions does this DJB assembly fit?

This part fits many GM full-size trucks, vans and SUVs from roughly 1999–2006 that use a 6-lug configuration with ABS. The listing covers front left and front right positions and is supplied as a two-piece set so both sides can be replaced together.

• Compatible makes: Chevrolet, GMC, Cadillac models listed (Silverado 1500, Sierra 1500, Tahoe, Suburban, Yukon, Escalade, Express, Savana, Astro, Safari).
• Years covered include common 1999–2006 model ranges and several 2003–2013 Express/Savana variants.
• Position: front axle, both driver and passenger sides; 6-lug wheels with ABS sensor provision.

What are the key specifications and reference numbers for accurate fitment?

The assembly is engineered to match OEM mounting geometry and bearing characteristics so it installs without bearing preload adjustments. Exact dimensions and reference part numbers help verify compatibility before purchase.

• Flange diameter 7.09 in, flange offset 1.97 in, bolt circle diameter 5.5 in.
• Wheel pilot diameter 3.06 in, hub pilot diameter 3.91 in; flange bolts: M14x1.5 thread.
• Reference OEM/alternate numbers included: SP450703, 515054, H515054, BR930762, WE60912 and others.

How does DJB design improve durability and installation ease?

DJB assemblies include design choices that reduce the likelihood of early failure and make replacement faster for mechanics or DIYers. They come sealed and ready to install, reducing exposure during handling.

• Quad lip seals help prevent contamination and limit installation damage to the seal area.
• Premium tapered roller and ball bearings for reduced friction and reliable high-speed operation.
• Pre-lubricated, pre-sealed units that require no bearing clearance adjustments during installation.

When should you replace both hubs instead of one?

Replacing both front hub assemblies at the same time is recommended when wear or failure affects one side, because bearings typically age similarly and dual replacement restores even handling and braking symmetry.

• Replace both if one hub shows noise, vibration, or grease leakage to avoid repeat labor.
• Dual replacement helps maintain ABS sensor consistency and wheel speed signal accuracy.
• Buying the pair saves time and often reduces overall cost compared with separate purchases.

Who is this for: The DJB 515054 front wheel hub and bearing assembly suit owners and technicians working on late-1990s to mid-2000s GM 6-lug trucks, SUVs and vans who need a robust, OE-compatible replacement. It’s aimed at people who want a ready-to-install, sealed hub with ABS provision to stop wheel noise, vibration, or leaking grease—without complicated bearing adjustments. Confirm vehicle year, wheel size and ABS needs against the reference numbers and dimensions before ordering to ensure an exact fit.
