SEAL-SIDE DOOR LOCK PILLAR UPPER(MUCKET) REPLACEMENT

MODELS AFFECTED: 1987 ALLANTE

Some 1987 Allantes built prior to VIN 102397 may exhibit one of the following three conditions:

- Excessive wear of the mucket (see Figures 1 and 2).

- Mucket may stick to the door when it is opened and result in hard opening effort of the door (see Figure 3).

- Soft-top 1/4 glass interferes with mucket. This will restrict the outboard movement of the 1/4 glass assembly (see Figure 4).

To repair this condition:

1.) Remove hardtop and lay it on a protected surface. 2.) Pull muckets off. 3.) Install new muckets, P/N 1645376 - RH, and 1645377 - LH. 4.) Reinstall hardtop.

For warranty purposes, use Labor Operation T6230 at .5 hour to replace both muckets.

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.
