Delphi Suspension Ball Joint P/N:TC549
Keep your steering tight and your suspension articulating smoothly with the Delphi Suspension Ball Joint TC5794, a front lower ball joint that connects the lower control arm to the steering knuckle so the wheel can pivot for steering while the suspension travels. It's a direct-fit replacement for the 2006-2010 HUMMER H3 and the 2009-2010 HUMMER H3T — a solid choice when you need a Hummer H3 ball joint or a Hummer H3T ball joint. If worn joints are behind the clunking over bumps, loose or wandering steering, or uneven tire wear on your 2007 Hummer H3, this replaces the failed front lower unit.
Delphi draws on its OE steering experience for the aftermarket, testing to extremes: parts withstand temperatures below -40°C and over 120°C and endure 720 hours of salt spray.
Ball joints wear as a pair — inspect and, if needed, replace the matching side for balanced handling.

What vehicles does the Delphi TC5794 ball joint fit?
It's a direct-fit front lower ball joint for the 2006-2010 HUMMER H3 and the 2009-2010 HUMMER H3T. See the Buyer's Guide tab to confirm your exact application.
Is this an upper or lower ball joint?
This is the front lower ball joint. It connects the lower control arm to the steering knuckle, allowing the wheel to pivot for steering while the suspension moves.
What are the signs my ball joint may need replacing?
Common signs include clunking over bumps, loose or wandering steering, and uneven tire wear. Have the cause diagnosed, since these can stem from other worn suspension parts too.
What material and protection does this Delphi ball joint use?
It's built with high-quality forgings and uses a chloroprene rubber boot for durability. Anti-corrosion protection is applied to each part for corrosion prevention and appearance.
Should I replace ball joints in pairs?
They wear as a pair, so it's good practice to inspect the opposite side and replace both if needed for balanced, even handling and steering.
