Check whether the U-bolt nut is loose? Does the clearance of the tension bar bushing become larger? Is the tension rod fastening screw loose? Find the reason for the change of wheelbase and isosceles.

If the bushing is damaged, replace the tension bar bushing after adjusting.

If the tension rod adjusting bolt is loose, readjust, lock the adjustable torque rod, install the slotted nut cotter pin and retest.

If the U-bolt nut is loose, loosen the nut, install the leaf spring and tension rod base correctly, screw the nut to the specified torque, and then adjust the isosceles and wheelbase.
