Scotty, I have a 2005 Jeep Liberty CRD. A family member drove it recently and appears to have switched it into part-time (winter/sand) 4WD and when I got in, the power steering pump is screeching. Could driving in full 4WD on hard surfaces have caused a power steering pump problem? I know it could have caused transmission and differential problems, but I don't notice any of those issues. Thanks, Brad in NJ

not a pump problem from that, but driving like a maniac could have damaged front end parts and cause it

Thank you!
