A genuine Lippert replacement drive-in wheel lug stud engineered for compatible 5,200-, 6,000-, and 7,000-lb trailer axle hub assemblies. When a stud is damaged, stripped, or snapped, this is the correct OEM-spec replacement to restore safe, properly torqued wheel retention.
Wheel lug studs are a safety-critical fastener. A single stripped or broken stud reduces clamping load across the entire wheel, which can lead to wheel loosening under load. The Lippert 132624 is the correct OEM-spec replacement stud for Lippert-branded axle hubs rated at 5,200, 6,000, and 7,000 lb, ensuring proper knurl engagement and thread engagement depth when installed correctly.
This is a drive-in stud -- it presses into the hub flange from the back side using a lug nut and a socket stack, or a hydraulic press, without requiring hub removal in most service scenarios. The 0.617" knurl diameter provides the interference fit needed to lock the stud securely in the hub bore and prevent rotation during torquing.
Fine-thread pattern for consistent torque retention and compatibility with standard 9/16" lug nuts used on trailer axle wheels.
Provides adequate thread engagement for standard trailer wheel lug nuts without protruding excessively through the wheel face.
Interference-fit knurl presses into the hub flange bore to lock the stud against rotation during installation and use.
Genuine Lippert part -- same spec as the studs installed at the factory on compatible 5,200- to 7,000-lb axle hubs.
This stud is designed for Lippert trailer axle hub assemblies in the following capacity ranges:
Before ordering, verify your hub's lug stud bore diameter matches the 0.617" knurl spec. If your hub uses a different knurl diameter or thread pitch (such as 1/2"-20), this stud is not the correct replacement. Check the Lippert axle label or hub casting number to confirm compatibility.
The 132624 is a press-fit drive-in stud. To install: remove the wheel, place the stud through the hub flange hole from the back, then use a stack of washers and a lug nut threaded onto the stud to draw it into the bore by tightening the nut. Alternatively, use a bench press for cleaner seating. The knurl must be fully seated flush with or just below the hub face for proper retention. Do not hammer studs in freehand -- doing so can damage the hub bore and compromise the interference fit.
This listing is for one (1) wheel lug stud. Most trailer hubs use five or six studs per hub. If replacing studs due to corrosion, fatigue, or impact damage, inspect all studs on the hub and replace any that show cracking, stretch marks at the knurl, or thread damage. Replacing studs in matched sets on a hub is recommended practice.
After installing a replacement stud, torque the lug nut to the wheel manufacturer's specification -- typically 90 to 120 ft-lb for 9/16"-18 studs on trailer applications, but always confirm against the axle or wheel manufacturer's published torque chart. Re-torque after the first 50 miles of travel following any wheel or stud service.
