Since December 1982, all Escort vehicles have been equipped with new type shock absorbers. The production of old type shock absorbers has been discontinued. It is prohibited to install old and new type shock absorbers on the same vehicle.
On the cargo-passenger version of the Escort vehicle, the rear suspension (Fig. 4.11) consists of a rigid tubular beam, single-leaf springs and telescopic hydraulic shock absorbers.

Length of springs 1194 mm, maximum thickness 15 mm, color mark: red and white for model 35; blue for model 55.
The rear wheel hubs (Fig. 4 12) are made as one piece with the brake drums and are mounted on two tapered roller bearings.

The bearings are filled with lithium grease according to the Ford SM1 C-4515-A specification. On the Escort XR3i and Orion 1.6 injection cars, the rear wheel hubs have been modified due to the installation of more powerful brakes. The hubs and brake drums are made as separate parts
The Escort XR3i has reinforced suspension springs. The Escort RS 1600 i also has springs marked in purple and orange.
Since September 1982, starting with serial number CB 08622, the rear suspension arm joints have been reinforced to improve their operation under maximum loads. The new joints can be installed on previously manufactured vehicles. Since these joints have a conical shape, they are installed and removed in one direction only. If the joints are replaced, adjust the wheel alignment to ensure a divergence of 0 to 2 mm. Since May 1983, Escort vehicles have been equipped with modified suspension arms to improve stability: the inner arm joint mount has been lowered by 25 mm, and the tie rod attachment point to the body has been raised by 30 mm, wheel toe-in has become 2.0 mm, and the dependence of toe-in and camber angles on load has been reduced. The new suspension arms and tie rods are not interchangeable with the old ones. All removed bushings, washers and rings are installed in their original places.
Since the 1984 model year, Escort vehicles have been equipped with more elastic joints. When replacing joints on earlier vehicles, do not install old and new joints on the same axle.
