We set the wheels to the position of straight-line movement of the car.
Inside the car…
...with a 12 mm socket, unscrew the bolt of the terminal connection of the fork of the upper cardan joint of the intermediate shaft with the steering shaft (for clarity, the steering column protective cover has been removed).
We move the hinge fork from the steering shaft.
In the engine compartment…
...using a 10 mm socket, unscrew the bolt of the terminal connection of the fork of the lower cardan joint of the intermediate shaft with the tail of the steering gear shaft.
We remove the cardan joint fork from the pinion shaft tailstock.
Using a 10 mm socket head, unscrew the three nuts (two are not visible in the photo) fastening the intermediate shaft seal plate to the front shield.
Location of holes for plate mounting studs (for clarity, shown on a removed shaft).
Having removed the seal from the front shield studs, we take out the intermediate shaft.
We install the intermediate shaft in the reverse order.
We position the cardan joint forks of the intermediate shaft so that the bolts of the terminal connections pass through the grooves on the steering shaft and on the tailstock of the pinion shaft. We tighten the bolts to the prescribed torque (see Appendices).
