Easy Stuff.....
Shifter bushing worn out and old
Power steering pump leaking
Brake fluid flush
Power steering flush
Steering stop caps worn
Rear differential leaking at speed sensorLittle bit harder stuff......
Clutch worn out
Valve cover gaskets leaking
Fuel induction/injector cleaning service
Upper and lower ball joints worn outNow, first thing I would attack would be the ball joints. They can cause premature tire wear, and if they completely fail, they can cause an accident. Check out the FSM manual posted in this forum at the top for a repair guide.
Degrease the power steering pump and hoses and go from there to find your leak. Does it groan and moan, or is it hard to steer? If so and your fluid level is full, the pump is on its way out and needs to be rebuilt or replaced.
Shifter bushings are a cheap easy fix. See here for the fix
http://www.off-road.com/toyota/tech/shifter/index.htmlPower steering and brake fluid flush are pretty simple. For the brakes I'd just keep bleeding each corner, pushing all the old fluid out while keeping the master cylinder full until only clear fluid comes out. Power steering fluid I would drain whats in the reservoir and just replace with new fluid.
Steering stops, well, just dab some grease on the stops at ever oil change. You can buy replacement plastic covers, but they will wear out quickly.
Rear diff leak, just unscrew the ABS/Speed sensor and there's probably a o-ring or it just needs to be tightened down.
The leaking valve covers can be more of a pita, especially the passenger side. You have to remove the intake plenum to get at the pass. side cover.
Fuel injection cleaning service, well, I don't know, if your getting good gas mileage and everything is running smooth, I'm not sure you need it.
If your clutch is truly worn out, you need to look into replacing it before it goes out and leaves you stranded. It's not really a extremely difficult job, the the proper tools are required, like a trans jack that you can rent, multiple ratchet extensions, and a good set of hand tools. Everything is tight and hard to get to, but with patience and time it can be done. Does it slip? Make noises?
hope this helps.
