Product Details

BBB Industries N734-77151 is a new power steering pump built for steering system repair on 2006-2011 Buick Lucerne and 2006-2011 Cadillac DTS models. The pump uses a cast iron housing, one reservoir inlet, and one threaded outlet sized M16x1.50. The reservoir is included, while the pulley, filter, cap, and sensor are not included. This part cross-references OE numbers 19320095 and 20759843 for the same application.

Common Repair Symptoms

• Hard steering effort at low speeds
• Whining or groaning noise from the power steering system
• Fluid leakage around the pump or reservoir area
• Reduced steering assist during turns
• Steering response that feels inconsistent or delayed

Installation Notes

Verify reservoir condition before installation and replace it when needed, since the reservoir is included with this assembly. Confirm the M16x1.50 outlet connection, reservoir inlet size, and three-mount-hole layout before installation on the vehicle. The pump uses a press-on pulley attachment type, so pulley transfer or separate pulley sourcing may be required depending on the vehicle setup.
