Thanks for the input. I have no fluid leaks at all, either inside or outside. I have a centerforce dual friction clutch with about 50,000km on it. The flywheel turned, new shifter seat bushing, etc. All done in March 2003. What should I look for first?

91 SR5 Xtra Cab, 298000km, 4" lift, 56" rear springs, 33-12.5R15 BFG Mud-Terran T/A KM2.....and an '85 axle still waiting to go in.
