Default Drivers Side Seat Rocking

Hello All,

Does/did anyone have thier drivers side seat rock on them? Mine has begun to do it slightly and I am looking for any advice on this. I may try to fix this depending on what I hear and see for myself.

Thank you! :confused:

This is a bonus fearture on the C5's. Some claim it's the little known RPO LZBOY option. There's is a TSB that addresses the issue. I've had it applied to my car and it's rocking again. I hope the C6 doesn't do this.

Get used to it. GM refuses to come up with a permanent fix. I keep hoping someone in the aftermarket will find a way to fix this once and for all, cause it's driving me :crazy: :mad :cuss

Did GM replace the seat adjusting assembly for you guys? I had that done over a year ago and the rocking seat has not returned.

I'm assuing GM repaired yours the way they did mine. In how long can I expect my seat to begin rocking again?

Thanks,
Pete

My seat started rocking after about 3,500 miles. After much jumping up and down, the dealer finally agreed to replaced mine. Came back around 3000 miles later. It may have some thing to do with my size, I weigh about 235, but I don't remember the brochure saying the seats were only rated for 150 pounders. :rolleyes:

Hmm, sounds like an ongoing issue. I weigh a little over 200 pounds but that shouldn't do it.

Easy fix, drop in a Sparco race seat and bolt it down yourself! :-) I just got my seat fixed under the TSB too, and now I'm finding the seat back is rocking on it's own (without the base). Think I will be taking my own advice...

Me too, but I a sort of fixed mine. I took the seat out of the car thinking I might figure out a way to fix it. Nope, there are pretty good sized rivits in place that would make this task less than appealing. Well after bolting the seat back in, I noticed the rock was nearly gone???? That's interesting. This seat moved a solid 1/8"-1/4" before???
As it turns out, by removing the seat and bolting it back in, I miss-aligned the two rails by enough that the slop in the left side picked up the slop in the right side and vise-versa on the fwd-bkwd movement.
With me?
The left track is in the furthest position (within the mounting whole) in one direction and the right track is in the furthest position of the mounting whole in the other direction. I stumbled across the suedo fix, but sure has made my car more pleasurable to drive. I now have maybe a 1/16" movement which is hardly detectable by my back side...

I hope that helps some.
One of these days, I'm going to drill out those rivits, remove the threaded adjusters, have a machine shop make new ones from metal, and bolt the thing back together.........one day....... :rolleyes:

"... remove the threaded adjusters, have a machine shop make new ones from metal ..." Does that mean that this problem is caused by threaded adjusters made out of crap, like plastic? And their TSB "fixes" the problem by replacing them with the same crap? That really makes me steamed! :banghead:

Now, provided that I own my car for the next however many years, does a TSB guarantee that I will get this fixed for free even after my warranty is up, or am I going to have to go on a rant with them every time it recurs? :cuss

Unless you're VERY lucky, they'll only pay for a TSB repair if it's in warranty. And then you still may have to jump upand down to get it done. I did.

Yes. My GM mechanic told me that some dealers would perform the TSB repair for free for cars out of warranty. Even if your dealer says no, see if they'll give you the new part for free - it is NOT a GM part (some Canadian company, whose name I can't recall, is the manufacturer), so it costs GM nothing for the part itself.

Wow, is that disappointing to hear. Replacing a broken part under warranty with the same known-to-be-defective part is almost criminal, especially when you know it is going to have to be repaired again once it is out of warranty. It's the same thing as the running light that keep getting moisture in them, replaced them both under warranty already, and they are both filled with condensation again. Thanks for all the info!

TurboPhil - nice to hear a "shade tree mechanic fix" on this. I have seen and heard plenty on this problem here, but precious little from those that have attempted to fix it themselves. Most are still under warranty, and that's the end of the story. I'm just starting to get the rock, and was wondering what to do at this point. Does anyone out there have a pic of what and where this worn piece is? I'm just nutty enough to go in there and see if I can find a fix for this. I just don't know where to look yet, and the seat isn't bad enough for drastic measures! And nice to see someone from the KC area - I grew up in Lawrence...

So that means you probably went to KU too huh. I'm a K-stater myself, but I won't that against you :thumbs:

On to business...

It takes all of 2 minutes to remove the seat. 4 easy to get to nuts and a quick-release wiring harness under the seat is all it takes...

Flip the seat over and you'll see the two adjusters within the tracks that are held in place by two phillips head screws. There are very large _steel_ rivits that prevent the removal of the track and thus the removal of the adjusters.

Therefore, one would have to grind/drill/wish or will/remove the rivits from either end of both tracks. Then have some all metal piece machined to replace what I assume to be a plastic insert within an aluminum adjuster housing....Whew...

It's all pretty intuitive once the seat is upside down.

Cheers!
