How do I order the correct Cross Tube?
A cross tube can be ordered using an OEM part number as a cross-reference. Since the cross tubes are a very simple part one cross tube may cover many applications and years. If an OEM part number is not readily available there are several important dimensions on a tie rod cross tube that should be identical to the part that you are replacing and by taking a few simple measurements, you can ensure that you are choosing the correct replacement and that the new part will be easily installed.
Length - Cross tube length is measured from end to end. The length of the tie rod tube is critical to the alignment of the vehicle and if the incorrect length is installed it may not be possible to correctly set the vehicle’s toe.
Internal diameter and thread - Cross tubes are internally threaded to accept the left and right-side tie rod ends. The thread is left-handed on one end and right-handed on the other to allow adjustments to the tie rod assembly length. The diameter must match that of the tie rod ends to the connection will be secure. The thread pitch will always be a fine thread, but the diameter of the tie rod ends, and the tie rod bar will change depending on the vehicle design.
External diameter - The external diameter of the cross tube is important for clearances between the bar and other suspension components. The outer diameter of the bar is decided by what clearance is available on the vehicle and how much strength is needed in the bar.
