Front Suspension - Squeaking Noise

NOISE - "SQUEAK" - RADIUS ARM BUSHING Article No.
SPACER 87-11-22
LIGHT TRUCK: 1987 ECONOLINE
ISSUE: A "squeaking" noise from the front suspension when the brakes are applied at low speeds may be caused by the radius arm bushing spacer. The bushing spacer may rub on the radius arm stud during braking and squeak once the paint on the stud wears off (1000-2000 miles/1600-3200 kilometers).
Figure 18 - Article 87-11-22:
ACTION: To correct this, install a pre-1987 level inner insulator (C5TZ-3B203-E), bushing spacer (D7UZ-3B244-C), and outer insulator (C5TZ-3B203-D) on each radius arm using the following service procedure, Figure 18.
NOTE: All three (3) parts MUST be changed at the same time to make sure the repair is effective.
NOTE: The 1987 level and pre-1987 level bushing spacer share the same service part number. However, they are not interchangeable and the 1987 level spacer MUST not be used. The bushing spacer(s) can be identified as follows.
Spacer Color Outside Diameter
1987 Level Dark Gray 70.0 mm dia. (2.7 inch dia.)
Pre-1987 Level Light Gray 64.0 mm dia. (2.5 inch dia.)
