My steering wheel has 1/4" slack. I feels like the shaft is disconnected for that 1/4". I cannot detect visible play in the tie rod end. But I don't have a helper to turn the wheel. Is the steering shaft from the wheel down the same as the Trail Blazer? On that forum there are posts about 2 set screws in the "U" joint that can loosen and cause slack in the connection. Has anyone else encounter this problem and was it a "U" joint.?
