When moving the mixer tiped over in the trunk and

First off -- if it's still under warrantee, you'll want to go to kitchenaid.com and find the nearest service center. The next thing I say starts with "void the warrantee" steps. :)

It's very simple to open a stand mixer to see if you've got a simple problem or a bad one.

Unplug it.

Follow the aluminum "Kitchen Aid" band to the back of the unit, there's one main screw. Remove this, and set it aside with the band which should come right off at this point.

Now, there should be two screws on each side of the unit where the band used to be. Remove each of these. They're all identical, so no worries if you mix them up.

Now you can lift the top off of the unit and see inside. The motor is at the back of the unit, the gear box at the front is where the oil is coming from. Try (GENTLY) to tighten the screws that hold the gearbox together. With a little luck, the gearbox screws had come loose and it was oozing oil out through the seals. If they're all firm, then you've got more serious problems and you'll want to find a service center for it.

If the leak was just that the gearbox housing was loose, then you can open it up and see the grease that's inside. It's very thick grease, not liquid oil at normal temperatures, but I don't know what type of grease it actually is in yours.

The grinding sound you describe makes me think you've broken or dislodged the bearing chase though, and you've got bits of metal and/or small (1 - 2 mm diameter) bearings loose in the gearbox.

Good luck!

well you should read the menual and u will know .
