- slowly raise the jack and bring the front axle to its attachment points. The bridge should fit into the guide pins. At the top of the shock absorber strut, insert it into the corresponding holes in the body. First install rubber supports on the racks. Raise the bridge to the end;
Figure 204. Removing the front axle
Figure 198. Front axle assembly: 1 — shock absorber strut right; 2 - lid; 3 — rack mounting nut, 90–110 N·m; 4 - Upper rubber support of the rack; 5 - front axle; 6 — bolt (with internal hexagon) steering joint mounts, 30–35 Nm; 7 — power steering hose; 8 — power steering return line hose; 9 - rack and pinion steering mechanism; 10 — brake system hose; 11 — tee of brake system pipelines; 12 — shock absorber strut left; 13 — intermediate steering shaft with joint; 14 — bolt for fastening the brake pad wear sensor wire; 15 — brake pad wear sensor wire; 16 — connecting bolt for fastening the bridge to the cross beam, 90–100 N·m; 17 — engine mounting bolt washers; 18 — engine mounting bolts, 80–90 Nm
- both shown in the picture 204 bolts (pos. 16 in figure 198) insert into the holes and tighten the bolts and their fasteners evenly in several stages with a torque of 90–100 N·m;
Figure 205. Marks on the pinion and housing of the rack and pinion steering mechanism indicating the position of the wheels straight ahead
- set the wheels straight. In this case, the marks on the rack and pinion gear and its housing must match, as shown in the figure 205;
Figure 201. Intermediate steering shaft with hinge
- install the intermediate shaft joint onto the gear (see figure 201), tighten the bolt (pos. 6 in figure 198) and tighten it to a torque of 25–30 N·m;
- slowly lower the engine onto the supports, tighten the mounting bolts to 85 N·m. Remove the lifting device;
- install air duct;
- screw on the union nuts of the power steering hoses and tighten them (it is essential to remove the clamps previously installed on the hoses);
- tighten the shock absorber strut mounting nuts to a torque of 90–110 N·m and close the caps;
- connect the brake hoses to the tees and tighten to a torque of 12–16 N·m;
- connect the brake pad wear sensor wire and tighten it to 10 N·m. Check if the wire is routed correctly;
- install the wheels and tighten the mounting bolts by hand. After lowering the vehicle, tighten the wheel mounting bolts to a torque of 160–180 N·m;
- install caps;
- bleed the brakes (see the relevant section);
- start the engine and let it run for a while. Turn the steering wheel several times from one extreme position to the other. Stop the engine and check the fluid level in the power steering reservoir. Add liquid if necessary.
