Sunday on my way back from camping in the sieras I stoped at a gas station in Madera. When I started leaving I get this weird click or crunch type sound that is pretty loud. I had the wheels turned (not full lock) and rolling forward really slowly. It sounded like it made the sound 2-3 times per wheel rotation, but I couldnt figure where it was coming from....has anyone had problems like this???? A little more info....I had just drivin 2hours down some steap grades using a good amount of brakes and lower gears with 4 people and a full to the brim load. I know this is vauge, but any suggestions you guys could give me would be great. OH...it stopped doing it after I pulled forward and put the tranny back in park. Was fine the rest of the trip. Then I noticed it alittle when I was pulling it in at home.
