Have an 03 T&C, 135K miles, newish tires (under 10K miles on them), properly inflated. Runs fine, drives smooth, steers and brakes straight... most of the time. 3 times in the past month have been at highway speed (65ish MPH) for 10-15 minutes and suddenly get a strong vibration through whole vehicle timed with wheel rotation. Drop it into Neutral, rev engine, brake, change lanes... all have no effect on vibration. First two times I slowed down and it kept happening all the way down through 40ish MPH and then I stopped the vehicle to check tires (all fine). When I restarted it was gone. Third time I just kept driving and it went away on it's own in a minute or so. Checked and no play in wheel bearings or steering. Brakes worn similarly on both sides front. After thinking about it and reading other posts, I'm leaning toward a CV joint being the problem but the intermittent nature has me wondering. Any other suggestions to look at? Anything in the rear wheels to look at? How best to check CV's/half shafts, or just replace both? At 135K I guess they don't owe me anything . Want to figure it out as the wife and kids use it most and having intermittent highway speed problems with the family truckster is never a good thing. Thanks!
