If your are not happy with some aftermarket parts, and i understand! Just go
to the dealer! they are still available.

Aftermarket is... aftermarket, most of the time, they are of lower quality,
even some german parts, i'm sure that they are not german MADE.

But in your case, if loose when you got them new, maybe they had a problem
already. Here is the way i see aftermarket parts: i check every parts before
i install those!
I return 5-10%, including the so so Empi complete axle.

Lately, i'm having some problems with upper ball joint, so i went to the dealer.
