Just wondering if anybody could tell what might be wrong with my 2002 dmax. Problem is there is a slight viberation when truck is in park maybe normal or start of potential problem. Truck has about 67,800 miles on it and only add ons is full 4" exhaust. Any suggestions would be great. Thank you

i notice a viberation on mine after the 4 inch exhaust..so i look underneath it and found that the muffler place had it resting on top of one of the cross members,so i fix quick..hope thats your problem

I have 100K on my 2001 and I notice a vibration that seems to repeat in a cycle when idling in park. I thought it was a Torque convertor thing or maybe a crank that isn't balanced quite right.....it's not a huge vibration......but now that someone mentioned exhaust....that could be it also....
