FRONT END NOISE ('POP') ACCELERATION AND/OR BRAKING

VEHICLES AFFECTD : 1985 Buick Electra with 3.0L (LK9) and 3.8L MFI (LN3) Engines

A 'squeak, crunch or popping' noise may be experienced on some early Electras during acceleration and/or braking. The condition is usually a single pop.

New dimensioned lower insulators went into production around January 2, 1985. The revised lower insulators should be used where comments of cradle pop are noted. Rework of mounts explained in Bulletin 84-2-122 should be used only if replacement parts are not readily available.

The following steps should be used to replace the lower insulators:

1. Remove lower insulators.

NOTICE: Do not disassemble more than two mounts at a time in order to maintain cradle and front end alignment.

2. Replace lower insulators with:

25525868 in No. 1 position (front mount) 25525871 in No. 2 position (middle mount) 25525870 in No. 3 position (rear most mount)

Two of each required per car. Soap or soap and water solution may be used as an aid in installation.

3. Torque cradle mounts to 103 N.m (76 lb. ft.).

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
