Well my trk only has 31000 miles. It happened after i got my bf goodrich ta ko 33" tires put on with a two inch level. I will have them rebalanced

RKing

The truck has 108K miles. I think will have it aligned and balanced this weekend. The previous owner put cheap general tires on it, this may be part of the problem.
I pretty sure it also needs the plugs changed, I am going to order the tool today. and test the COPs tonight. I will also inspect the driveshaft.

The problem its kinda wierd. Its perflectly smooth at 70mph. This morning was 25° out, this seemed to make it a little worse than yesterday when it was 48°.

Thanks for the help guys.
