A constant velocity joint having a boot constructed from a thermoplastic polyether ester as the boot material. The boot includes a lubricating grease composition for lubricating the constant velocity joint, the lubricating grease composition comprising calcium lignin sulfonate.

In one aspect, the disclosure relates to lubricant compositions comprising an oil, a wax, or a combination thereof, wherein at least one of the oil or the wax comprises a very long chain fatty acid; and wherein at least one of the oil or the wax has been modified via a transgenic route to increase a concentration of the very long chain fatty acid relative to a reference concentration of the very long chain fatty acid in the oil or the wax without the modification. In a further aspect, the VLC FA can include one or more of eicosenoic acid, erucic acid, or nervonic acid.
