Rear Springs - Clicking/Clunking Noise
Number 87-3-9 Date 1/87Subject: REAR SPRING CLICKING/CLUNKING NOISE
1984-87 FIERO MODELS
Some 1984-87 Fieros may exhibit an audible clicking/clunking noise originating from the rear of the vehicle.
This noise may be the result of the coils of the rear springs contacting one another during normal jounce/rebound motions of the rear suspension.
Vehicles exhibiting this condition may be corrected by following applicable procedures indicated below by model year.
1984-86
On all 1984-86 vehicles, replace rear springs in conjunction with installation of new formed spring isolators, P/N 10068755. Applicable Service Manual procedures should be followed for removal and installation of springs and isolators which must be positioned as shown in attached Illustration.
1987
On 1987 vehicles assembled prior to October 27, 1986 and equipped with rear springs coded NXD, follow procedure above for 1984-86 vehicles. All other 1987 vehicles assembled prior to October 27, 1986, will only require installation of new spring isolators, P/N 10068755. Installation of isolators on these vehicles can be achieved by supporting vehicle so that rear suspension is in a full rebound position, therefore not requiring rear strut removal and disassembly.
When spring replacement is required, proper spring selection can be determined by utilizing either the prefix code on spring tags or prefix code on the vehicles "Service Parts Identification Label" and refering to chart below:
