I replaced the PS pump about a month ago. the engine mounts are definitely starting to break down and look kind of rotten from the PS fluid. I am experiencing a low pitched, intermittent 'hum' or groaning noise from the motor when at idle, otherwise the engine runs fine (the groan from the PS pump is gone after the new pump). The main crank pulley appears to have a small bit of wobble, but the two other pulleys attached at the same point do not wobble. Plenty of oil pressure, water pump is pumping plenty of water, not sure about the smog pump (it was super caked with crud when I did the PS pump) Probably just being paranoid... Any ideas? would worn mounts lead to slight angle changes and weird noises? Harmonic balancer out of whack? Also, I can hear the bearings in the transmission when the clutch is out and in neutral. Thanks in advance for any ideas. I'm hoping to fix problems that could get worse down the road. If I get a warm enough day and some time I plan on swapping the transmission oil and differential oil. Also need to do oil change, valve adjust, timing, and carb adjust. The thing is a bit of a dog in the hills with 3.7's and 31" tires, and gets 11mpg. Plenty of climbing power in 4lo off road.
