Seat Springs-Anyone have parts book/diagram?

My seat rocks a small amount when accelerating and I have finally grown tired of it.

I pulled the seat out and seems to have found the issue.

These rear springs appear to be not applying enough upward pressure on the rear of the seat....perhaps a previous owner was a big fella.

Regardless, I can’t seem to find the part number or name anywhere. Leaving for a road trip on Saturday and hoping to replace by then.

Also, has anyone replaced these? Any tips?

Thanks in advance.

You can’t see them in the first picture, but the red is their approximate location. There are 2 springs, one at each rear corner of the driver’s seat.

Wow that's super specific, may be worth a call to a dealership to see if they can get an exploded view. Another option would be to measure the spring and potentially find a new set on the internet.

Very interesting. My seats do the same thing and it drives me crazy. I was going to look into it, just didn't have time to yet. I'll try to find a generic replacement but may not be able to get to this before you leave on your trip.

Ya, guessing that is the route I will need to go.

I will keep you posted. I took most the the bottom seat apart as I also have a heated seat issue.

I put everything back together and the rock appeared to be gone. I didn’t have time to test drive it today, but will know after driving it tomorrow....

If it is solved, I am guessing that the stereo installer (amp is under seat) or a past owner had the seat out and didn’t button it back together correctly....

I found this today and it looks like the spring you're looking for. Item #6.

Thanks for the reminder to update the thread...

I had found those springs too, however, they say they don’t fit my model year (2008).

With that being said, I am proud (actually, just happy) to report that after I disassembling and reassembling the seat, the rocking is gone!!

If I had to guess, I would say I think it was one of the clips circled in blue. When I reassembled the chair, the clips appeared to be re-attached properly, however, I hadn’t heard one of the “snap” into place. It was awkward to get the proper angle, but eventually it snapped in. (And as reported, the rocking is gone...I am not sure how/why it would have been removed previously, but at 12yrs old, I don’t know what the PO have done to it.)

With that being said, I had researched the web a lot on this issue prior to diving in. Some people reported issues with a bolt that they had to wrap tape around, others had loose mounts....It appears there are a variety of issues that can cause the rocking I described.

Once you get the seat out, which is literally takes about 15 minutes, (4 Allen bolts, and a torx for the seat belt), the culprit should be pretty obvious.

In my case it wasn’t so obvious, as after I had the seat out laying on the garage floor, it still rocked, leading me to believe it was those springs.

There are quite a few clips/snaps that hold everything together. I encourage you to tackle the project. I was hesitant to take the seat out, but it couldn’t have been simpler.

Good luck with your fix.

Nice! Glad it's resolved and you can get back to enjoying the truck!

I'll likely be taking the passenger seat back out in a month or two to fix an SRS fault, I have been reading that the weight sensor in the seat has a high fail rate. So tired of seeing the SRS periodically come on. :|

But I love these damn trucks!
