A seal between two telescoping members in a slip yoke assembly including a driveshaft section and a slip yoke. A circumferential groove is formed in the outer surface of one of the telescoping members of the slip yoke assembly. The groove defines an annular collar which extends circumferentially about the end of the slip yoke. One or more recesses are formed in the bottom of the groove. Additionally, one or more axially extending slots are formed through the collar. Preferably, the slots are angularly offset from the associated recesses by a predetermined amount. One or more radially inwardly extending protrusions are formed at one end of the seal. To install the seal on the slip yoke, the seal is initially oriented relative to the end of the hollow cylindrical end portion such that the protrusions are axially aligned with the slots. Then, the seal is moved toward the slip yoke until the protrusions engage the outer end surface of the slip yoke axially adjacent the slots. Axial movement of the seal continues until the protrusions of the sealing member are circumferentially aligned with the groove. At that point, the seal is rotated such that the protrusions move circumferentially through the groove. Such rotation is continued until the protrusions snap into the recesses formed in the bottom of the groove to quickly and easily retain the seal on the end of the slip yoke.

A fixture for identifying the phase angle relationships between two universal joints secured to the ends of a steering shaft assembly includes first and second universal joint assemblies which are connected together by a shaft assembly. The shaft assembly includes a male splitted member which is secured to a first inboard yoke of the first universal joint assembly. The male splined member extends within and cooperates with a female splined member of the shaft assembly. The shaft assembly also includes a hollow cylindrical extension member having a first end which is secured to a second inboard yoke of the second universal joint assembly. The extension member has a second end which is journalled on a reduced diameter end portion of the female splined member. Thus, the extension member and the second universal joint can be rotated relative to the female splined member and the first universal joint assembly. A band is provided on the outer surface of the female splined member at the end adjacent to the reduced diameter portion and the extension member. The band has a series of indicia which are visible throughout the entire outer surface of the female splined member. A 0.degree. reference point of the indicia is axially aligned with the first inboard yoke of the first universal joint assembly. A reference arrow is provided on the outer surface of the extension member at the end adjacent to the extension member. The reference arrow terminates in a point which is directly adjacent to the indicia. The reference arrow is axially aligned with the second inboard yoke of the second universal joint assembly. The indicia and the reference arrow cooperate to provide an indication of the phase angle between the first and second universal joint assemblies.
