Hey guys, I was just testing out my Bob V. shifter knob tonight, so I had her in 4 HI, as I was coming to a stop there was alot of noise and vibration coming from the front. What could this be?, is this a normal thing?. Should I be worried?. I do have these awful Super Swamper SSRs, and suspect they have something to do with it, but any other "you should check this" recomendations are very welcome. Thanks!
