I'll check the heater hoses, that makes more sense, thanks. I was thinking it was the front wheel hubs/bearings, too. I did change them out around 50k and 70k, so logic told me that they definitely could be due. I ordered up some new SKF front hubs and installed them both this weekend. I was assuming the truck was going to glide down the road but unfortunately, still there. Also have brand new tires. When I grabbed onto the original hubs, there wasn't much movement but I had already bought the new ones for $300, so went ahead and did them. Assumed with that amount of miles, there soon to be due. Unfortunately, didn't fix it.
