The general information

Forward suspension bracket

Components of a forward suspension bracket (model 2WD)


1 — a stabilizer Bar 2 — the Screw spring 3 — Soshka of the steering mechanism 4 — Adjusting муфта steering draught of the right wheel 5 — Average steering draught 6 — Connecting steering draught 7 — the Cross-section jet bar 8 — Carter of the bridge	9 — the Bottom lever of a suspension bracket (the top levers in a picture are not visible) 10 — the Beam of the bridge with the forked end 11 — the Left tip of connecting steering draught 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 (model 4WD)


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 draught of the right wheel 5 — Average steering draught 6 — Dempfer of a steering drive 7 — the Cross-section jet bar 8 — the Bottom lever of a suspension bracket (the top levers in a picture are not visible)	9 — Differential 10 — Carter of the bridge 11 — the Beam of the bridge 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 power shaft CV-hinge 14 — the Left tip of steering draught 15 — the Tube of a regulator of steering draught of the left wheel 16 — Connecting steering draught

All models of mark of cars described in a given Management are equipped by the rigid forward bridge. On models 2WD the continuous tubular sleeve is applied; on all-wheel drive (4WD) models two steel sleeves of semiaxes are welded from each of the parties to pig-iron картеру differential (the Head Coupling and трансмиссионная a line more in detail see). The forward bridge is suspended by means of pair shock-absorbers and two screw springs. Four operating levers of a suspension bracket provide freedom of moving of the bridge in a vertical direction; horizontal displacement are limited by 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 spherical support, запрессованных accordingly in the top and bottom ends of the forked beams welded on end faces of the bridge.

Back suspension bracket

Components of a back suspension bracket (it is shown model 4WD, 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 — the Bottom lever of a suspension bracket (the top levers in a picture are not visible)

The back bridge consists from pig-iron central картера in which the differential is placed and steams of the steel tubular sleeves welded to картеру from its both parties (in the Head Coupling and трансмиссионная a line more in detail see). The back bridge is suspended by means of pair shock-absorbers and two screw springs. Four operating levers of a suspension bracket provide freedom of moving of the bridge in a vertical direction; horizontal displacement are limited by 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 put to a steering wheel through system of draughts of a steering drive (сошка, average and connecting steering draughts) to levers of rotary fists of operated wheels is applied retsirkuljarno-ball type. Демпфер, established between the bridge and average steering draught serves for softening of an undesirable deviation of operated wheels from the chosen direction at a suspension bracket course).

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

The national security service of traffic of the USA (NHTSA) lets out the special bulletin on critical components of a steering column of models 115,000 Jeep 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 of a steering 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, рассоединение the top and bottom shaft of a steering column conducts to full loss of controllability of the car that is fraught with emergency occurrence . If such defect appears is revealed on your car, it is necessary to address in dealer branch of company Jeep/Chrysler where are obliged to make corresponding repair free of charge. Are issued special intensifying муфты, intended for additional installation on an intermediate shaft for the purpose of restriction люфта columns. In case of occurrence of the problems demanding carrying out of repair, call in local zone management of company Chrysler - number it is possible to find"Service"of the operation manual on the car in Section. It is possible to communicate also on hot tenches with management NHTSA (1-800-424-9393) or to address in service of reception of claims under number (800 424-9153.

At work with suspension bracket and steering components it is often possible to face the problems connected with отдаванием of fixture. The fixture is under the bottom of the car and is subject to constant influences of a moisture, a road film, a dirt, etc. that leads it прикипанию and to complications at отдавании. For decrease in risk of damages at отдавании such "become attached" fixture the set of various type of getting structures with which during some it is necessary to impregnate fixing knot before отдаванием is issued. Зачистка an open carving part of fixture a wire brush also reduces danger of damage of a carving at отдавании bolts and nuts. Often to destroy "soldering" of a bolt with a nut it is possible by means of sharp blows of a hammer (through кернер), however it is necessary to accept safety measures against соскакивания кернера 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. Any application of collars and lengthening pipes allows to raise essentially size of the twisting moment applied on 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 a twisting direction (clockwise). Fixture, отдавание which has caused special difficulties at assemblage of knots should be replaced.

As the majority of the procedures described in the given Chapter, assumes поддомкрачивания the car and performance of works under it, it is necessary to take care in advance of presence of strong props for car keeping in the lifted position. For поднимания the car preferably use of a jack тележечного type which also can be applied for подпирания separate components during performance of works.

At all does not follow at performance of 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 assemblage it is necessary to pay steadfast 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 another way to straighten the deformed components of a suspension bracket or a steering - always replace their new.
