Tamiya Tractor Truck Alloy Trailer Rear Axle TRU074 by GPM  [TRU074]

Trailer axle replacement for scale rigs

This alloy rear wheel axle serves as a scale replacement part for Tamiya Tractor Truck trailers. It provides a solid mounting point for wheels in the trailer rear assembly and helps maintain alignment under load. The part is for hobby model maintenance and tuning, not for use on real vehicles.

Make sure fitment is to the Tamiya Tractor Truck trailer rear assembly described in the product title before ordering. Removal of the wheel and hub is usually required, followed by inserting the axle through the trailer mounts and securing with original fasteners. Check hub fit and bearing condition to confirm smooth rotation and correct endplay during installation.

Tuning notes: an alloy axle increases torsional stiffness compared with stamped steel components and this can influence how the trailer transfers load. When changing suspension geometry or wheel offsets, verify clearance with nearby mounts and body supports. Keep fasteners torqued to spec and routinely inspect for wear signs.

Ideal for repairing or upgrading a Tamiya Tractor Truck trailer rear end; use correct hubs and bearings, follow original torque values, and recheck wheel alignment after the initial run.
