Hey Bill, In the area i live, this salt will eat your vehicle in half
I was under my buddies 06 F350 4x4 checking the starter and it looked like a 30 year old vehicle. The mechanic had to torch the bolts to get it off. So yes salt is a major issue up in here in N Michigan.
As far as the sensor issue, I too have a harness problem and the wheel sensors often go before the bearing starts making noise.I don't change them due to sensor failure but when they make such a noise and start heating up. I wish I knew what the problem with Aleros is but I had to change it out just after I bought the car out of lease and waranty at 36 K.
Back to the salt issue ,as a warning to others. The rack and pinion - steering gear, is set on a thin tin mount welded on the subframe, and many have rusted off as mine did recently. The sub frame even has a large valley that salt sand water can sit in and to top it off the AC drain hose is right over the R-P. Did a search and found others , some driving down the road and the steering locked up and some got in accidents. I was lucky I was in my driveway when mine ripped off the mounts. Thanks for your reply
