Mobile Semi Truck, Trailer & Tanker Repair, Welding & Fabrication Services in West Memphis, AR & Memphis, TN – What We Fix

24/7 Spindle Repair / Replacement

TJ’s Fab & Mobile Repair is a certified provider of United Axle’s on-site spindle repair system. We replace your damaged spindle right on your truck or trailer, restoring it to OEM strength without removing the axle housing.

Drive, steer and trailer axles. Our mobile unit inspects the housing, checks bearing journals, removes the damaged spindle, installs a precision-welded replacement, reassembles bearings/seals/hubs, aligns and road-tests.

Signs of a worn spindle

• Excessive wheel-end heat or burnt-smelling grease
• Grease leaking past the hub seal
• Wheel wobble or vibration at highway speeds
• Uneven or accelerated tire wear
• Grinding or scraping near the hub
• Blue, black, or discolored spindle metal
• Hub movement when rocking the wheel
