Cv Joint

Recently I noticed that my driverside cv-joint has messed up. For some reason there is splatter from the boot of the cv-joint all on the suspension parts and inside of the wheel well. The passenger side is dry. Anyone know what is wrong. 95 4-runner 3.0 EFI V6 4X4

Boot is split. Get a remanufactured half-shaft installed. You can replace the boot, but there is little difference in labor between replacing the boot and replacing the half-shaft. The parts costs are pretty cheap on a reman.
