Abstract
An apparatus for adjusting wheel alignment at an upper ball joint assembly of a vehicular suspension includes a bushing having an outer surface defined about a first axis, and a receptacle defined about a second axis eccentric to the first axis. The apparatus further includes a locking key having an arm portion adapted to removably cooperate with selected ones of slots arranged radially in a flange portion of the bushing so as to retain the bushing in a predetermined position.
Claims20
A vehicular wheel alignment device, comprising:
- a bushing having a first portion for mounting at least partially about an upper ball joint stud of a vehicular suspension, and a second portion for selective engagement with a locking mechanism, said first portion including a first receptacle having a first central axis that is eccentric to a second central axis of said bushing, said second portion of said bushing including a plurality of slots disposed about said second central axis, said plurality of slots being configured for removable engagement with said locking mechanism.
An apparatus for adjusting wheel alignment at an upper ball joint assembly of a vehicular suspension, said apparatus comprising:
- (a) a bushing having:
- (i) an outer surface defined about a first axis;
- (ii) a receptacle defined about a second axis eccentric to said first axis;
- and
- (iii) a flange disposed at a first end portion of said bushing, said flange including a plurality of slots arranged radially about said first axis;
- (b) a locking key having an arm portion adapted to selectively and removably cooperate with any one of said plurality of slots so as to retain said bushing in a predetermined position, said locking key being removably securable to said upper ball joint assembly.
An apparatus for adjusting wheel alignment at an upper ball joint assembly of a vehicular suspension, said apparatus comprising:
- (a) a first element mountable about a first axis defined by a ball joint stud of the upper ball joint assembly, said first element having a first engagement feature and being selectively rotatable about said first axis;
- and
- (b) a second element securable to the upper ball joint assembly and selectively rotatable about a second axis that is substantially perpendicular to said first axis, said second element having a second engagement feature adapted to removably engage with said first engagement feature to secure said first element at a predetermined one of a plurality of circumaxial positions about said first axis.
A method for adjusting wheel alignment at an upper ball joint assembly of a vehicular suspension, said method comprising:
- (a) providing an adjustment apparatus, comprising:
- (i) a bushing having a first central axis and a first receptacle having a second central axis that is eccentric to said first central axis, said bushing further including a first engagement feature;
- and
- (ii) a locking element having a second engagement feature adapted to removably engage with said first engagement feature;
- (b) mounting said first receptacle of said bushing at least partially about a ball joint stud of the upper ball joint assembly;
- (c) securing said locking element to the upper ball joint assembly about a pivot axis that is substantially perpendicular to said first central axis;
- (d) positioning said bushing in one of a plurality of pre-defined circumaxial orientations about said second central axis;
- and
- (e) engaging said first and second engagement features to one another by pivoting said locking element about said pivot axis until said second engagement feature comes into an engagement relationship with said first engagement feature in a locking position.
