I was going down a pretty steep gas line the other day and the EBS or ADC was really squeeling. I never heard it make this noise before. I tried a few different smaller hills and it didnt do it. Have any of you had this happen before? Is it a common prob. or something to start looking into? I've been down this hill before and never had this noise. Got me wondering

 

if you decend a steep hill in high range, sometimes it will overpower the belt and squeel. Try using low range if its steep.

 

Sounds good that makes sense. Now I noticed that one of my sway bar bushings is split. Wasnt there a service bulletin about them they had some bad ones that cracked up.

 

My ADC system has never made any noise, just a leaky seal once.

I don't think there was a service bulletin on the bushings, just a bad batch of them. All the bushings on my new 800 were dry rotted when I got it. Dealer just handed me eight brand new ones with no questions asked.
