Steering elements are removed for repair or replacement.
We examined the removal of the steering wheel in the article - Removing and installing the steering wheel of a Renault Duster car
We examined the removal of the power steering pump and bleeding the system in the article - Removing the Renault Duster power steering pump.
In this article, we will consider the removal of the remaining elements of the car's steering system.
Removing the steering column
We remove the steering column for replacement as an assembly in case of failure of the column shaft bearings or universal joints of the intermediate shaft.
We remove the steering column switches (article - Design and replacement of Renault Duster steering column switches) with a coiled cable drum device.
We remove the instrument cluster. Disconnect the ignition switch wire blocks and the immobilizer coil from the wire harness blocks.
The steering column can be dismantled in two ways - with the removal of the instrument panel or without removing the panel.
Let's consider both methods.
We remove the instrument panel (article - How to remove the Renault Duster instrument panel).
With a head of 13, we unscrew the nut of the special bolt securing the coupling of the lower cardan joint of the intermediate shaft to the steering gear shaft.
We take out the bolt.
Special bolt and self-locking nut for fastening the coupling of the lower universal joint of the intermediate shaft
Remove the lower universal joint coupling from the gear shaft
With a head of 13, we unscrew the four bolts securing the steering column to the bracket of the cross beam located under the instrument panel
We remove the steering column.
To remove the steering column without removing the instrument panel:
Using a Torx T-20 wrench, unscrew the two screws securing the instrument panel to the rear steering column mounting bracket
Using a 13 head, unscrew the two upper bolts securing the steering column to the cross beam bracket.
From under the instrument panel, unscrew the two lower steering column mounting bolts.
With a 10 head, unscrew the nut of the steering wheel adjustment mechanism bolt
We take out the bearing
We take out the handle
Remove the rear steering column bracket.
Then, moving the upper part of the steering column so that it does not catch on the elements of the instrument panel and the cross beam, we push the column down through the hole in the instrument panel
And remove the steering column.
Install the steering column in reverse order.
We mount the coupling of the lower cardan joint on the gear shaft of the steering mechanism so that the coupling fastening bolt is aligned with the flat of the gear shaft.
- steering wheel mounting screw - 44 Nm;
- bolt securing the steering gear housing to the subframe - 125 Nm;
- a bolt of fastening of an arm of a steering column - 21 Nm;
- fastening of the steering rod to the rail - 34 Nm;
- Tie rod end locknut - 50 Nm;
- a nut of fastening of a spherical finger of a tip of draft - 37 Nm;
- hydraulic booster pump mounting bolt - 25 Nm;
- the nut of the coupling bolt of the universal joint of the steering shaft - 21 Nm.
Tie Rod End Replacement
The tie rod end is replaced if its ball joint fails or the joint boot is damaged.
We work on level ground
We remove the front wheel from the side of the tie rod end to be replaced and securely fix the car on the stand.
Turn the steering wheel all the way in the direction opposite to the tip to be removed.
The work is shown on the example of the left tie rod end, the right tie rod end is changed in the same way.
We mark the position of the tip relative to the steering rod
Using a 21 wrench, loosen the locknut, holding the tip with a 19 wrench by the flats.
Before unscrewing the nut that secures the tip pivot pin to the steering knuckle lever, clean the Torx key hole at the end of the pin with a metal brush from dirt.
Using a 16 wrench, we unscrew the nut that secures the tip hinge pin to the steering knuckle lever, if necessary, holding the finger from turning with a Torx T-30 wrench.
Using a puller, press the tip pin out of the steering knuckle eye.
In the absence of a puller, we unscrew the finger nut not completely.
We insert the mounting blade between the tie rod end and the steering knuckle arm.
Squeezing the tie rod end down with a mounting blade, and striking with a hammer at the end of the steering knuckle lever, we press the finger out of the hole in the lever.
It is also possible to extrude a finger by striking with a hammer through a soft metal spacer on the butt of the finger.
In this case, support the steering knuckle with an adjustable support "A".
We remove the ball joint pin from the hole in the lever
We unscrew the tip by hand, counting the number of revolutions by which it turns away, if necessary, holding the steering rod from turning by the hexagon with a 13 wrench.
Install the tie rod end in reverse order.
We screw it onto the threaded end of the tie rod for the same number of turns (or up to the marked mark) on which it was screwed until removed.
Tighten the locknut of the tip and the nut of the ball joint pin to the prescribed torques.
After completing the installation of the tie rod end, it is necessary to check and, if necessary, adjust the toe-in of the wheels on a special stand - at a service station.
To adjust the wheel toe-in, it is necessary to loosen the lock nut of the tip, remove the spring clamp and rotate the steering rod by the hexagon with a 13 wrench, holding the tip with a 19 wrench.
Tighten the locknut to the torque indicated above.
Replacement of a cover of the steering mechanism
If the steering gear boot has lost elasticity, cracked or torn, it must be replaced.
Remove the tie rod end as described above.
Loosen the tie rod lock nut
Compress with pliers and remove the spring clamp of the cover
We bite with side cutters the clamp of the protective cover on the steering gear housing or unclench it with a screwdriver
We remove the clamp
Remove the protective cover of the steering mechanism
Install the new cover in reverse order.
Tie rod replacement
We replace the tie rod when there is play in its ball joint.
We install the car on a viewing ditch or lift.
Operations are shown on the left tie rod.
The right tie rod is removed in the same way.
Remove the tie rod end as described above.
We remove the protective cover.
With a pipe wrench No. 2, we unscrew the body of the tie rod joint from the rack, holding the rack by the first tooth with a key of 22.
Removing the steering wheel
Install the new tie rod in reverse order.
Before installation, apply a small amount of fixing sealant to the threaded part of the tie rod ball joint.
We check and, if necessary, adjust the angle of convergence of the wheels.
Removing the steering gear
The steering gear is removed for repair or replacement. With the help of a pear, we pump out the fluid from the power steering reservoir.
We disconnect the tips of both steering rods from the steering knuckles.
In the passenger compartment, disconnect the universal joint coupling of the intermediate shaft of the steering column from the steering gear shaft.
Before disconnecting the hydraulic lines from the crankcase of the steering mechanism, we substitute a wide container under the crankcase to collect fluid.
Using a 17 key, unscrew the fitting of the drain pipe
We remove the tip of the tube from the hole in the crankcase of the steering mechanism and insert plugs of a suitable diameter into the holes of the tube and crankcase.
We also disconnect the tube of the discharge line.
The connection of the drain and discharge pipes is sealed with rubber rings.
We replace them if they have lost elasticity, cracked or deformed.
On the left side, with a 10 head, unscrew the bolt securing the bracket to the steering gear housing
Using a 21 head, unscrew the bolt securing the steering gear housing and bracket to the front suspension subframe
After disconnecting the wiring harnesses, remove the bracket.
We unscrew the bolt securing the steering gear housing to the front suspension subframe on the right side.
We substitute an adjustable stop under the rear of the subframe. Weaken the tightening of the front bolts securing the subframe to the body, approximately four turns.
We unscrew the rear bolts securing the subframe to the body and remove the two subframe amplifiers
We lower the rear part of the subframe by 90-100 mm on an adjustable stop.
We derive the steering gear shaft from the hole in the front end shield.
We take out the steering mechanism through the arch of the left wheel.
Install the steering gear in reverse order.
Before installation, we check that the rail is set to the middle position.
We tighten the bolts and nuts with the moments indicated in this article.
