View Full Version : Aluminium Ball joint vs Steel Ball joint?

Just like the title says, My car has steel control arms, but when I put new ball joints in 3 months ago they only had Aluminium ones, they look just the same as the steel ones, so I bought them, when I took my car to GM for a 44 point inspection they said my ball joint boots are broken.

Is this the difference between Aluminium ball joints and steel ones?

I bought 2 new steel ball joints today and I'll install them next week.
Thanks, and BTW there is no threads on this.

Well, did they say specifically just the boots? The boot and the ball joint are two seperate pieces. The rubber boot has like a metal ring inside that holds it down on the ball joint, so if the ring is cracked it won't stay down and you'll get dirt in the ball joint. If that's all it is, you should be able to just get new boots. Shouldn't have to replace the whole ball joint.

Yeah, just the boots were cracked, but there is play in the ball joints aswell,
the steel one to me looks longer.
