My 03 developed a slight abillaty to lift up on the steering wheel at around 10k. It also developed a slight vibration in the steering wheel when turning slowly over rough surfaces at about 10k. I thought I might of been dreaming but these problems became amplified over time. At 20,660 the sensations were unbearable. You could here a clunking coming from the engine compartment. I took my truck to the dealer and they performed T.S.B. 00-02-35-003C. They also did there 21 point lube/ inspection and performed a 4 wheel alignment. The truck felt and drove great. I did feel some very slight symptoms of the previous problem but I chalked it up to mucle memory. It is now 3 weeks later and 1418 miles down the road and I am noticing the same symptoms again. I am sure they will become amplified with time. What is you suggestion on my next course of action?
