Under carriage power wash

[guamboyeli]

I just bought my first awd and im excited to get it running... So I put my car on jack stands and looked underneath to check out the diff and drive shaft mount... Then I noticed that it was so filthy... Grease and dirt all on the undercarriage grease from broken rear axles and who knows what... So my question is, is it safe to power wash the under carriage...like from the front tires on back??? Do I have to be careful of getting something wet???

Good question. I run ALL my vehicles at least twice a month through those automated washes with the high pressure undercarriage wash. Even the eclipse. The belts squeak a little but id take that over rust ANY day, wouldnt you? None of my vehicles i have done this with develop rust underneath. I highly recommend it.

I wouldn't see a problem with it, just make sure you don't have a open wires, holes from rust, etc.
