Seat Movement Issues

That's what happens when you're the manager and you're the only employee and your mind screwed from working so much.

I took my Sierra into the dealer at my last services and complained about this. They found no issue. It is very noticeable.

I will have them fix it under warranty (both front seats).

I had the fix done on my 15 Silverado and the movement and click came back in a few days time. I installed worm clamps to the inside of the bar pressed again inner part of the clip. Drove to a few places so far today and have not had the seat move or click. This thread has helped take care of the only gripe I have had with this truck.

After the GM fix, it worked, then came back. Added a hose clamp, it worked, then came back. Added two more clamps (see picture a few posts up), tightened the first clamp, and it worked. So far so good this time with 900 miles on the latest fix.

 

I think clamping down the GM piece and isolating both sides with additional clamps is the ticket. I'll report back if it starts up again.

My seat was very loose side to side and front to back, it also made popping and creaking  noises especially when making turns with truck. After several trips to Dealer and paying for a half baked repair I had enough. I fixed my self and Installed washers on seat adjuster that moves the seat up and down and seat bottom tilt. The factory bolts threads bottom out and do not allow a tight fit and even with the plastic spacer the Dealer puts in per the bulletin there is still excess play and movement. See pics below with space I am talking about and pics on how to fix. I checked several other seats and they all have the same issue. This is a design flaw from the factory and I can't believe they have not addressed it.

Ok, based on the above pictures that were shown I fixed mine last night. It literally took me 10 minutes to fix the issue.

 

Push the drivers side seat all the way back and all the way up. There are two up functions on the switch, make sure both the rear and front sections are up. Look by the center console side of the seat on the underside, you will see the motor there that actuates the front of the seat up. It is bolted in a black metal bracket, has a T30 torx bolt holding it in and the bolt is fully seated but has a gap by the head.

 

That is the issue, the gap. You can grab that motor as it is on a rod that goes across the front of the seat and is what rotates the front of the seat up. Grasp the motor and move it side to side, you will hear and feel the "clunk" that is felt when you are turning. Here is the fix, it is stupid easy and simple.

 

You will need some channel lock pliers, a T30 torx bit and a flat washer. Remove the T30 torx bolt and pull it out. You will notice it is a shouldered bolt, only threaded about a 1/4" or so. Now take the pliers and grab the bracket ears and bend them in together slightly. Just enough to take up the gap that allowed the motor to rock side to side. Now with a washer that will slide onto the bolt and down to the head, slide the washer on and then put the motor back into the bracket and slide the bolt/washer back into place and tighten the bolt down. Make sure to not bind the bolt up, check operation of the front height seat motor and make sure it goes up and down properly.

 

Thats it, you have now fixed the seat clunk on the seat. Had mine done for two days now, no more clunk in mine either.

so the fix is basically the black clips?? Do they just snap on?

Pretty much. There are two plastic washers that are on the bulletin. It states to install them as well and A tube of lube. I couldn’t get the washers in and left it with just the retainer clip. It’s been over a month and haven’t heard it or felt it move since. It was about $20 for all, $12 was just for the lube.

The bulletin also says to partially remove the seat cushion, so you can move the the white piece freely to get it lubed well.

ahh, so thats not something you can just reach up under with the clips and pop on then

I’m sure you can. I was just following the directions and it seems that the reason for cushion removal was to remove the bolts to the seat pan, so you can move the white piece, so you can lube it. Lol.

Thanks! 

 

I was just gonna toss on some hose clamps but perhaps I'll pick up a couple of those clips and try them.
