Front Wheel Bearing Hub for GM SUVs

This Moog front wheel bearing hub fits 2002-2009 Chevrolet Trailblazer, GMC Envoy, Buick Rainier, Oldsmobile Bravada, Isuzu Ascender, Saab 9-7X and Chevrolet SSR models. It replaces multiple dealer part numbers including 513188 and 12413037. The unit is designed for driver or passenger side front position on both rear-wheel and four-wheel drive configurations. It comes new in black finish with all necessary mounting hardware included.

Thermals Noise and Power Draw

As a mechanical wheel-end component, this hub assembly generates no electrical power draw and produces no fan or pump noise during operation. The sealed bearing design operates silently within the steering knuckle under normal driving conditions. Integrated ABS sensor and 37.4 inch wiring harness function passively without adding parasitic load to the vehicle electrical system. Normal use involves only rotational friction from the 27-spline non-driven hub.

Sustained Load Behaviour

Under continuous cornering and braking loads, the 5.905 inch total hub diameter and 4.649 inch height maintain structural integrity through the three mounting bolts and six M12-1.50 lug bolts. The 55-tooth tone ring provides consistent ABS signal accuracy during extended high-speed operation. Flange offset and 5.925 inch flange diameter distribute shear forces evenly across the three flange bolts. The unit is not intended for driven axle applications requiring torque transfer through the splines.

Questions about this item

How is the ABS sensor wiring harness routed during installation, and which step is often missed?

The 37.4-inch harness must be clipped along the knuckle and control arm before the three flange bolts are torqued; skipping the routing clips lets the harness rub the CV joint.

What replacement interval applies to the integrated ABS tone ring on this hub?

The 55-tooth tone ring is pressed into the hub and is not serviceable separately; it lasts the life of the bearing unless physical damage or corrosion forces a full hub change.

Which load limit is reached first during extended towing with this non-driven front hub?

The three M12-1.50 mounting bolts to the knuckle and the 27-spline axle interface share the cornering and braking loads; sustained heavy trailer use typically yields bolt stretch before bearing fatigue.
