File In Section: 08 - Body and Accessories

Bulletin No.: 00-08-50-014A

Date: October, 2001

TECHNICAL
Subject:
Driver's Power Bucket Seatback Movement During Braking
(Replace Seatback Recliner Assembly and Bolts)

Models:

2000 Chevrolet and GMC C/K Pickup (Silverado and Sierra) and Utility (Suburban, Tahoe, Yukon, Yukon XL) Models

This bulletin is being revised to clarify the type of seat involved and revise the Parts and Warranty information. Please discard Corporate Bulletin Number 00-08-50-014 (Section 08 - Body and Accessories).

Condition

Some customers may comment that the driver's power bucket seatback moves forward about 25 to 38 mm (1 to 1-1/2 in) during moderate to heavy braking.

Cause

To reduce the amount of vibration being transmitted through the seatback, a spring was incorporated into the driver's bucket seat recliner assembly. This spring pre-loads the seatback to assist in absorbing and reducing vibrations being transmitted through the seatback and into the headrests when the vehicle is in motion. The forward movement of the seatback during moderate to heavy braking is the result of the pre-loading.

Correction

Advise customers that bucket seatback movement of 25 to 38 mm (1 to 1-1/2 in) during moderate to heavy braking is considered normal. However, for those customers who desire to have the seatback movement addressed, replace the driver's bucket seatback recliner assembly and attaching bolts. This recliner assembly does not have the pre-load spring used to reduce vibrations. Prior to installation, customers should be advised that there may be some vibration transmitted through the seatback and into the headrest with this recliner assembly.

Parts Information

Parts are expected to be available October 10, 2001 from GMSPO.

Supercede:

This bulletin is being revised to add model years and additional Warranty Information. Please discard Corporate Bulletin Number 05-08-50-012 (Section 08 - Body and Accessories).

Condition

Some customers may comment on unwanted seat movement in the front power bucket seat (driver or passenger) during fast acceleration or hard braking. A metal to metal clicking noise is often heard at seat "stops."

Cause

The threads of the two zinc nut retainers (one on each side of the seat adjuster) may creep over time, causing a loss of self-rolling screw clamp load and ultimately causes relative rail and vehicle seat motion.

Correction

Apply adhesive and install new bolts in seat mounting rails using the following procedure.
1. Remove the front seat and invert onto a flat surface covered with a clean, non-scratch material (soft cloth or similar). Refer to the applicable Seats sub-section in SI. Adjust so that the seat mounting rails are at 45 degrees.

2. Remove the upper M8 mounting bolt from one rail and discard. Leave the other bolt intact as this will hold the track in place while working. Wipe the bolt hole area with a clean rag.

Important: Only use the adhesive provided in the repair kit. Do not substitute with other adhesives.

3. Take one of the adhesive sachets and carefully cut the flag tip off the notched end spout in line with the notch.

4. While holding the sachet vertical, slowly dribble the adhesive into the edge of the bolt hole as shown, ensuring that the adhesive flows into the joint between the seat rail and the zinc block. DO NOT pour the adhesive down the center of the hole. The object is to let the adhesive "wick" between the zinc block and the seat rail in order to bond the two pieces together.

Important: If the bolt thread strips or the proper torque cannot be achieved, then the entire seat adjuster mechanism must be replaced.

5. Replace the previous bolt with a new M8 bolt (1) (included) and install using a "click torque wrench" preset to 9 N.m (79 lb in).

6. Remove the second M8 mounting bolt from the rail and discard.

7. Repeat steps 2 through 5 for the second bolt.

8. Repeat steps 2 through 6 for the opposite mounting rail.

9. Before installing the seat into the vehicle, verify that the seat will function correctly and does not make any unusual noises during forward and rearward travel motion.

10. Install the seat. Refer to the applicable Seats sub-section of SI.

11. While sitting in the seat, verify seat function and listen for any unusual noises.

I understand, but thats not my issue my whole seat slides forward when you come to a stop and slides back when you take off about a 1/4 " either way. If you have the seat all the way forward or all the way back it does not slide. All functions of the seat work.

The second bulletin refers to the seat bolt's coming loose which doesn't sound like your seat. Those are the only two bulletin's I see for seat movement. If you can help me find that post where you say that bulletin was mentioned I can find out which bulletin they were talking about. It could be one of the one's I already posted but we won't know until I find it to find out. Otherwise my best advice is that you will have to pull the seat and see what's loose. It could just be a worn seat track. Was it in the chevy truck section you saw it?Was it a older post?Please help me help you.
