Patent ID: 7384673

Claim:
A system comprising a convoluted boot in a constant velocity joint and a lubricant for a constant velocity joint, the boot comprising a thermoplastic elastomer material selected from the group consisting of polyurethane (TPU), polyamide (TPA), polyolefins (TPO), polyester (TPEE), or a thermoplastic elastomer vulcanizate (TPV) or a thermoplastic poly-ether-ester-elastomer (TEEE), wherein the convoluted boot and the lubricant contain an additive comprising amide waxes in a concentration below the saturation limit in the convoluted boot, and a diffusion-promoting admixture, wherein the diffusion-promoting admixture is provided in the form of phosphoric acid ester, fatty acid ester, or thioether wherein the phosphoric acid ester and fatty acid ester are both in the form of diester or polyolester.
