Take a look at this thread. your description sounds like the same rod, different model loader.

Have you checked your hydraulic fluid level since you got it home? I can't see how the bearing/bushing being out would keep the loader from lifting. If it was seized tight the loader cylinders would break it loose, or break it off.

You say "got several hydraulic leaks,had hose bust,", so I would agree with Delmer that first thing you need to do is make sure you have enough oil in the hydraulic tank. I just hope when hose burst you did not keep running it when low on hydraulic oil or else you may have destroyed the pump.

If you can post a picture of the "bearing" you think is out of place and stopping it from moving it would make it much easier to give you correct answers.

One more thing, you said bucket won't lift. How about all the other functions? Bucket roll back and dump. Can you pick the front end off the ground by rolling the bucket forwards? Do all the back-hoe functions work, outriggers/stabilizers lift the rear off the ground?
