Highway Spindles
Shop our drive axle spindles, 4707/4709/4515, 4707-2, Bendix, and Allen spindles, which include the sleeve, gasket, and hardware for a bolt-on install. The Meritor Highway Spindle fits Meritor axles, while the Meritor International 4700 fits RR20-145, MS1714X, and MT40-14X axles. Confirm your axle model before ordering, since the two aren’t interchangeable. For concentrated, high-stress loads, the Kenworth T800 spindle is built to T800 46,000-lb tandem drive axle dimensions, and the Heavy-Duty Crane spindle fits Freightliner and other heavy-duty crane axles.
Mack Truck Spindles
Our Mack spindle product lineup is crafted from forged steel and subjected to a multi-stage heat treatment, withstanding heavy loads and offering long-lasting durability. Available in small and large sizes for standard Mack highway trucks. The Mack Granite Spindle is built for Granite dump trucks and other heavy-duty Granite models (S402R, S522R, S582, S652, GR64BR), and the Mack CH613 Spindle is made specifically for commercial hauling and CH613 trucks.
Straight Truck Spindles
We carry straight truck spindles for Meritor and Spicer axles under trucks like Freightliner M2, Kenworth T380/T480, International MV/HV, and Hino, plus dedicated spindles for Isuzu NPR medium-duty trucks. These swap in without a full axle replacement, cutting long hours down to about 90 minutes and restoring proper wheel alignment and load distribution. The Isuzu NPR 250 and NPR 550 options are ready-to-fit for medium-duty delivery and box truck applications, check your original spindle’s dimensions and part numbers against the product specs before ordering.

This category includes a heavy-duty replacement spindle for 2500/3500 series, Chevrolet Express and GMC Savana vans. This spindle is recommended for American Axle Manufacturing (AAM) 12″ rear axles or 10.5” rear axles. Made from high-strength steel, these replacement spindles are built for commercial cargo van applications where standard pickup spindles don’t fit.
Not Sure Which Spindle You Need?
Match it to what’s already on the part you’re replacing, not to truck type alone. Check the weight capacity, product dimensions (bearings, seal, and locknut), and the axle model tag on your old spindle against the compatibility section under each SKU on the product pages. If you are still unsure, contact us with the details, and we’ll confirm fitment before you order.
When to Replace Truck Spindles
Spindle failure on a truck usually gives subtle warning signs before breaking down altogether. If you’re seeing any of these, inspect the spindle itself, not just the bearing or seal, before ordering parts.
⚠ Grinding, squealing, or clunking noise
You may hear an unusual noise during turns or braking, which is often the first sign of a worn bearing surface or a damaged spindle.
⚠ Vibration in the wheel
A worn spindle bearing surface lets the hub move side to side. If a new bearing doesn’t fix it, especially at higher speeds, the spindle is the problem.
⚠ Overheating at the wheel hub
Excessive heat near the hub, even after short drives, can indicate insufficient lubrication or a damaged bearing riding on a worn spindle surface.
⚠ Poor steering or handling
You may find your truck constantly pulling to one side, notice delayed steering response, or that the tires are unbalanced. Misalignment caused by a worn spindle shows up as difficulty steering or uneven tire wear.
⚠ A bent or cracked spindle
A bent spindle is visible at a glance, usually after a curb strike or hard pothole hit, and it takes the truck out of service the same day. A crack, even a hairline one, is a structural failure risk and should never be run on.
Frequently Asked Questions
How much does it cost to replace a truck spindle?
Part cost varies by truck type. Pickup truck spindles run $485 to $765. Drive axle and Meritor highway spindles run $750 to $792.50. Straight truck spindles (Meritor and Spicer) are $845. Mack spindles range from $750 to $1,650 depending on the model. Isuzu NPR spindles run $875 to $1,175. Heavy-duty crane spindles run $2,850 to $3,250. These prices don’t include bearings, seals, hub hardware, or installation labor, which varies with the extent of the damage.
Are your drive axle spindles bolt-on or weld-on?
The 4707/4709/4515, 4707-2, Bendix, and Allen drive axle spindles use a patented bolt-on design. Straight truck and pickup spindles are weld-on and require the appropriate tooling.
How do I know which pickup truck spindle fits my truck?
For exact compatibility, match it by make, model, production year, and axle type. Before ordering, check the product page’s axle compatibility details, or contact us with your VIN or axle tag.
How do I ensure maximum life for the spindle wheel seals?
Seal life typically depends on a clean, properly seated install and a spindle surface free of rust or scoring, along with correct bearing preload and regular hub lubrication. If a seal keeps failing on the same wheel end despite that, the spindle itself is worn and needs replacing, not just the seal.
How does frequent dump truck operation affect its overall lifespan?
Dump trucks load, cycle the bed, frequently use brakes under heavy loads, and unload multiple times per shift; each cycle subjects the spindle to a shock load as the bed drops. Job-site dirt works into the seal, increasing bearing wear, and tighter, slower turns add more side-loading than linear highway driving. All that adds up to more wear per mile, so dump trucks need shorter inspection intervals than highway trucks.
Do your products include kingpin bushings?
No, kingpin bushings, bearings, and seals are excluded across the lineup; they’re wear items tied to your specific axle and mileage. However, where applicable, we sell installation hardware, which you can purchase separately as accessories from our shop: sleeves, gaskets, ABS mounts, and bolts for the drive axle series, and spacer sleeves for Mack spindles.
What comes in the box with my spindle order?
It depends on the spindle type, as the installation procedure differs for each truck. The 4707/4709/4515, 4707-2, Bendix, and Allen drive axle spindles ship with the spindle, sleeve, gasket, ABS mount, and bolts, everything needed for a bolt-on install. Mack spindles ship with a spacer sleeve where the model requires one. Meritor and Spicer straight truck spindles ship with a sleeve. Meritor Highway, Meritor International 4700, Crane spindles, and pickup truck spindles ship as the spindle on its own. Check the descriptions on each product page to confirm before you order.
