I am having an issue with my CV joints flinging grease from the boot.

Basically it flung a small amount of grease from passenger inner joint and drivers inner since day one but recently it has gotten a little worse and i can see grease on the firewall, trans, wheel etc from every axle (passenger inner and outer and driver inner and outer).

It seems like it was worst this last weekend when did a road course track day (4 20 minutes sessions in the Arizona heat). I will try to post pictures later.

I assume it's a boot sealing issue but I'm not ruling out other factors like a grease overheating issue or a geometry on the coilovers? I wanted to chime in here to see if anybody else had any ideas or experience with this. Can/should the boots be tightened up beyond how I received them?

Vehicle information is below

Vehicle: 86 Plymouth Horizon
Transmission: Large Spline 568
Axles: O'reilly Reman 1990 Automatic Axles (both replaced at same time when i installed the transmission)

Thanks!
