General information

Forward suspension bracket

Components of a forward suspension bracket (2WD model)


1 — a stabilizer Bar 2 — the Screw spring 3 — Soshka of the steering mechanism 4 — the Adjusting coupling of steering draft of the right wheel 5 — Average steering draft 6 — Connecting steering draft 7 — the Cross-section jet bar 8 — Carter of the bridge	9 — Nizhny the suspension bracket lever (the top levers in a picture are not visible) 10 — a bridge Beam with the forked end 11 — the Left tip of connecting steering draft 12 — the Spherical support of fastening of a forked beam of the bridge to a rotary fist (the top spherical support in a picture are not visible)

Components of a forward suspension bracket (4WD model)


1 — a stabilizer Bar 2 — the Connecting link (rack) of the stabilizer 3 — the Screw spring 4 — the Tube of a regulator of simply steering draft of the right wheel 5 — Average steering draft 6 — the Damper of a steering drive 7 — the Cross-section jet bar 8 — Nizhny the suspension bracket lever (the top levers in a picture are not visible)	9 — Differential 10 — Carter of the bridge 11 — a bridge Beam with the forked end 12 — the Spherical support of fastening of a forked beam to a rotary fist (the top support in a picture are not visible) 13 — the CV hinge of a power shaft 14 — the Left tip of steering draft 15 — the Tube of a regulator of steering draft of the left wheel 16 — Connecting steering draft

All models of brand of cars described in this Management are equipped with the rigid forward bridge. On 2WD models the continuous tubular sleeve is applied; on all-wheel drive (4WD) models two steel sleeves of semi-axes are welded from each of the parties on a pig-iron case of differential (for more details see. Head Coupling and transmission line). Peredny Bridge is suspended by means of pair of shock-absorbers and two screw springs. Four managing directors of the lever of a suspension bracket provide freedom of moving of the bridge in the vertical direction; horizontal shifts are limited to means of a cross-section jet bar. The stabilizer of cross-section stability serves for prevention of a swing of a body. Each of rotary fists is positioned by means of pair of the spherical support pressed respectively in the top and bottom ends of forked beams, welded on bridge end faces.

Back suspension bracket

Components of a back suspension bracket (it is shown 4WD model, for not all-wheel drive models the scheme is similar)


1 — the Shock-absorber 2 — the Screw spring 3 — the Cross-section jet bar 4 — a bridge Sleeve	5 — Differential 6 — a stabilizer Bar 7 — Nizhny the suspension bracket lever (the top levers in a picture are not visible)

Zadny Bridge consists of a pig-iron central case in which the differential and pairs of the steel tubular sleeves welded on a case from its both parties (Coupling for more details see in Head and the transmission line is placed). Zadny Bridge is suspended by means of pair of shock-absorbers and two screw springs. Four managing directors of the lever of a suspension bracket provide freedom of moving of the bridge in the vertical direction; horizontal shifts are limited to means of a cross-section jet bar. The stabilizer of cross-section stability serves for prevention of a swing of a body.

Steering

In system of hydrostrengthening of a wheel the box of the steering mechanism which transfers the rotary effort enclosed to a steering wheel through system of drafts of a steering drive (a soshka, average and connecting steering drafts) to levers of rotary fists of operated wheels is applied retsirkulyarno-ball type. The damper established between the bridge and average steering draft serves for mitigation of an undesirable deviation of operated wheels from the chosen direction at a suspension bracket course).

The shaft the helmsman of a column fastens to the mechanism of a steering box by means of the small kardanny hinge. The design the helmsman of a column provides its folding at blow during failure.

The national security service of traffic of the USA (NHTSA) issued the special bulletin on critical components of a steering column of models 115,000 Jeeps Grand Cherokee of release since December 1992 till July, 1993 in which it is told that:« The cast finger made of plastic serving for connection of the top and bottom shaft the helmsman of a column can appear cut off at installation of a steering column on the car. In this case the top steering shaft can separate from bottom». In turn, «the helmsman of a column conducts a rassoyedineniye of the top and bottom shaft to complete loss of controllability of the car that is fraught with emergency emergence». If such defect appears is revealed on your car, it is necessary to address in dealer office of the Jeep/Chrysler company where are obliged to make the corresponding repair free of charge. The special intensifying couplings intended for additional installation on an intermediate shaft for the purpose of restriction люфта of a column are issued. In case of the problems demanding carrying out repair, call in local zone management of the Chrysler company - number can be found in the Section "Service" of the operation manual on the car. It is possible to contact also on «hot tenches» management of NHTSA (1-800-424-9393) or to address in service of reception of claims according to number (800) 424-9153.

At work with components of a suspension bracket and a steering it is often possible to face the problems connected with an otdavaniye of fixture. The fixture is under the bottom of the car and is subject to continuous influences of moisture, a road film, dirt, etc. that leads to its "prikipaniye" and complications at an otdavaniye. For decrease in risk of damages at an otdavaniye of such "become attached" fixture the set of various type of getting structures with which during some it is necessary to impregnate fixing knot before an otdavaniye is issued. Cleaning of an open carving part of fixture by a wire brush also reduces danger of damage of a carving at an otdavaniye of bolts and nuts. Often to destroy bolt "soldering" with a nut it is possible by means of sharp blows of a hammer (through a center punch), however it is necessary to accept precautionary measures against a center punch soskakivaniye from an external surface of fixture and its hit on a carving part. Warming up of fixing knot by a gas cutting torch is extremely effective also, however in practice application of such way is undesirable in connection with real danger of ignition. Different application of collars and lengthening pipes allows to increase essentially size of the torque attached to a head of a key, however it is not necessary to apply lengthening pipes complete with ratchet drives is is fraught with failure of the ratchet mechanism. Sometimes to shift the "become attached" bolt or a nut attempt of its rotation helps with the twisting direction (clockwise). The fixture, which otdavaniye caused special difficulties at assembly of knots it should be replaced.

As the majority of the procedures described in this Chapter, the car and works poddomkrachivaniya under it assumes, it is necessary to take care in advance of existence of strong props for car keeping in the lifted situation. For a podnimaniye of the car preferably use of a jack of telezhechny type which also can be applied to a podpiraniye of separate components during works.

At all does not follow at works under the car to rely on reliability of its fastening in the lifted condition only one jacks!

After easing or removal of any fixture of components of a suspension bracket or its steering it is necessary to examine attentively and, in case of need, to replace (corresponding on a standard size and a design). At assembly it is necessary to pay close attention to observance of the efforts of a tightening of carving connections recommended in spice. At all do not undertake attempts to warm up or in a different way to straighten the deformed components of a suspension bracket or a steering - always replace them new.
