front end shake or shimmy revisited
--------------------------------------------------------------------------------
This was the original post: (Ok here goes; See my profile and signature for unit info. I have a shimmy that feels like an unbalanced tire that started on rough I20 in Louisiana. It gets so bad at my preferred speed of 62 to 63 that the dash bounces horribly. I have replaced the front and drive tires with 6 Michelin 235X85R16 XPS Rib. All the tire balancing has been double checked and different tires put on front. The front end has been aligned and ball joints and king pins checked. The stabilizer bar has a new shock. Both sway bars have new bushings. New shocks have been installed. The shimmy is still there. Suggestions anyone?!?!)
IT WAS A TAG AXLE TIRE!!!!! I had stupidly discounted the tag axle because the shake was felt mostly in the dash and steering. It was transmitted through out the frame. Lesson learned by me and admitted fully.
