OEM Replacement Axle Parts

OEM replacement axle parts keep a factory-style axle working: hub assemblies, wheel studs, axle shaft seals and bearings, spindle bushings and rebuild kits for Dana axles. It serves Jeep and truck owners repairing a leaking seal, a worn bearing or a damaged differential. Brands include Omix-Ada, Crown Automotive, Dana Spicer and Alloy USA. Check each product page for the axle model and fitment, then compare the products below.

Crown Automotive front hub assembly for Dana 30 axles

Factory axles wear in small, predictable ways: a seal weeps gear oil, a hub bearing starts to growl, a disconnect fork wears out and the front axle stops engaging. These are the factory-style pieces that fix those problems on Dana and AMC axles under Jeeps and light trucks, without replacing the whole housing.

Hub assemblies are the biggest group, followed by axle shaft retainers and the shift forks, guides and bearings used in disconnect-style front axles. Smaller groups cover tube seals, differential bearings, shims, spacers, rebuild kits, hub keys, spindle nuts and bushings, studs and housing ends. Many parts are sold one per side, so check the quantity before you order a pair.

Have on hand for axle work

  • Fresh gear oil of the grade your service manual calls for
  • Gasket maker or a new cover gasket
  • Torque wrench for spindle nuts, hub bolts and bearing caps
  • Seal driver or a socket matched to the seal's outer edge
  • Dial indicator if you are setting ring and pinion backlash

Axles changed mid-generation, and some listings cover only certain trims. Read the axle tag or ring gear size before ordering seals, bearings or shims.

What is in this category

This category covers maintenance and repair parts for factory-style axles, particularly Dana axles found in Jeeps and light trucks. The pieces are the small and mid-size components that wear out over time: seals, bearings, shims, studs, hubs and rebuild kits. Subcategories separate parts by function, such as axle shaft bearings, differential rebuild kits, spindle bushings and disconnect actuator forks.

Common repairs and the parts they need

  • Leaking axle seals: inner and outer axle seals and seal retainers. A leak that reaches the brakes is a safety concern.
  • Humming or loose wheel bearings: hub assemblies, axle shaft bearings, spindle nut and washer kits.
  • Broken wheel studs: replacement studs and lug stud sets, matched to the thread size and hub.
  • Differential noise or rebuilding: master rebuild kits, differential bearings, spacers, shims and ring and pinion bolt sets.
  • Front axle disconnect issues: shift forks and actuator parts.

How to choose

The most important step is identifying your axle. Dana 25, 27, 30, 35, 44 and similar axles use different parts, and even the same axle can differ by year, spline count, bearing type or brake setup. Look at the axle tag, or check the housing, tube diameter and ring gear size. Decide whether you want an OEM-style replacement or an upgraded part, and note that some parts, such as hub assemblies, are sold as complete units while others, such as bushings, are single pieces.

Specs to compare

  • Axle model and position (front or rear, driver or passenger side).
  • Spline count, bearing and seal size, and thread size for studs and nuts.
  • Whether shims, seals and hardware are included in a kit.
  • Whether a part is new, OEM, or from an aftermarket maker.

Installation and safety notes

Axle and bearing work is safety critical. Replace seals and bearings in the manner and order the service manual specifies, set bearing preload and gear backlash with the right tools, and torque spindle and wheel hardware to specification. Differential setup is a precision job, so use a qualified shop if you lack experience. Confirm fitment for your exact year, make, model and axle, and read the manufacturer's specifications before choosing.

Planning a repair

Axle repairs are easier when you gather parts before you start. Seals, bearings and shims are sold by axle model, so pull the wheel and inspect what is actually there before choosing. Take note of the number of bolts on the hub, the stud size and whether the axle has disconnect hardware, since these details separate one version from another.

Consider replacing related wear items together. If you are replacing an axle shaft seal because of a leak, check the shaft surface for scoring and the bearing for roughness. If you are rebuilding a differential, replace the bearings, seals and hardware as a set so you do not have to open it again soon. Refill with the correct gear oil and check the vent. Finally, take a short test drive and look for leaks or noise after the first few miles. Keep all removed shims labeled, since their position matters during reassembly and setup of the gears.

OEM Replacement Axle Parts FAQ

How do I find out which Dana axle I have?

Check the axle tag, the housing shape and the cover bolt pattern, and look up your vehicle's build information. Dana 30, 35 and 44 axles look different. Confirm fitment for your exact year and model before choosing parts.

Is a hub assembly the same as a wheel bearing?

A hub assembly usually includes the hub, bearing and mounting hardware as one unit. A wheel bearing is a single component pressed or set into the hub. Which one you need depends on your axle design.

Why do axle seals leak?

Seals wear with age and heat, and a scored shaft, a clogged vent or a failed bearing can cause leaks. Replace the seal and check the shaft and bearing condition, because a leak onto the brakes is a safety issue.

Can I rebuild a differential myself?

It is possible, but setting gear backlash and bearing preload takes the right tools and experience. Mistakes can lead to noise and early failure. Many owners use a qualified shop for this work.
