Hello everyone I have a question about rear tie rods for the C6 now could those bad cause vibration at high speeds. Thanks

No rear tie rods on my C6 so can't answer that. How is your wheel balance?

Tie rods exist in the front suspension only. Most times vibration at speed is caused by imbalance of the wheel & tire or in rare cases, the rotor itself. Find a shop with a Hunter Road Balance machine & have all four wheels balanced.

I think what the OP is referring to is the rear links that run from the spindle to the frame rail that have the adjustment feature for alinement. The bottom attachment is similar to a ball joint which also has a grease zerk if Z-51 equipped.The only thing that I can think of that would cause a vibration is if the link was loose or damaged. Get a four wheel alinement and four wheel balance. I really don't think the links are your problem. Have the tech closely inspect the suspension, tires, shocks, ball joints including the end links while the car is on the rack.

As stated, have all 4 corners check for alignment, and have the tires road forced balanced.

Also, when the tires are off the rims, have the tech spin the rims up to see if they are bend. The C6 uses low profile tires, so it not hard to bend rim. On the positive note, rims and be straightened.
