Description

GM Power Seat Forward/Aft Gear Repair Kit (Solid Brass)

Stop wasting money on entire power seat assemblies. Fix your GM vehicle’s forward/aft seat adjustment mechanism permanently with our precision-engineered Solid Brass gear set.

The power seat adjustment mechanisms in 2007–2014 GM vehicles commonly fail due to weak, brittle plastic gears. When these gears chip or strip, dealerships force you to purchase a complete new power seat unit—containing the exact same failure-prone plastic components. GruvenParts offers a superior, bulletproof alternative designed to last the life of your vehicle.

Installation Overview

  1. Access: Remove the power seat from the vehicle and flip it upside down to access the bottom structure.
  2. Frame Prep: Grind the rivet heads on the front main cross member to remove it. Oversize the hole to 1/2" to accommodate the included steel repair bushings.
  3. Gear Replacement: Open the gearbox and remove the old plastic gear from the spiral shaft (Dremel tool recommended).
  4. Bonding: Use a 24-hour epoxy (e.g., JB Weld 24-hour, not the 5-minute version) to bond the two halves of the brass gear onto the main spiral shaft.
  5. Reassembly: Reinstall components using the steel repair bushings to secure the frame rail.

    Another fine product

    Posted by Gary Theobald on 2nd Dec 2024

    I just finished installing the forward/aft seat gears in my 2008 Silverado. The product is working fine, seat now moves forward and back again. I found that using a small bottle jack to expand the side frame members worked quite well in lieu of prying the frame with pry bar or screwdriver. Just like the replacement gears for side mirrors, these are well made and work perfectly.

    gear for forward/backward movement

    Posted by Joey Salazar on 7th Nov 2024

    I’m glad I found this brass gear for my 07 Yukon passenger front seat, it’s a little bit of work to install it but better than buying the bottom seat assembly which is not cheap. So far it’s working great.

    Easy to install if you are handy with tools. I installed mine without removing seat bottom from the frame.

    glad i kept looking for a solution to my problem.

    The only thing that I would change would be the video attached to this product. There are things that I would change such as just flipping the bushing around. It would not need to be JB welded. I also use a saws all to cut off the weld, which left the end of shaft nice and clean. If I do this again, I will definitely make my own video to share.

    Parts are Working

    The parts fit and are in the chair. The price was a bit high. The chair is functioning and that is worth the money.

    Good product, but could be improved

    Posted by Eduardo on 28th Dec 2022

    I agree with previous reviews that both the video and written instructions are missing key steps that would help most save a lot of time. When I installed the bushings on the end of the shaft I noticed they fit very lose. After I installed the seat everything works great, except now I feel my seat move forward and back every time I brake or accelerate. I looked into it and found that the lose tolerance of new bushings is the problem. The shaft is shifting back and forth in the bushing due to excessive play. Now I have to figure out how to address that problem. -- response -- What bushings are worn out ? We can probably make these too, please contact me.

    Works Great, Nice Repair!

    Posted by Marcus on 2nd Sep 2022

    This is a nice kit to replace the gears in the FWD/AFT motion drive. I installed it on a 2007 Suburban driver's seat. I used a Dremel with cut-off wheels to cut off just the rounded heads of the rivets on the ends of spiral shaft. At that point I couldn't see a seam in the metal between the shaft and the shoulder of the rivet. After some hammering and prying I could begin to see the seam and was able to separate the rivet shoulder from the shaft. Once that was done, I used a grinding stone on the Dremel to remove some metal on the shaft ends to allow the other parts to slide off of the shaft. On reinstallation, I did not reinstall two spacers that were originally on the shaft, just inside the seat frame. Without these, the end sleeves were just about the perfect length - not too long as was described in the video. After waiting for the epoxy to cure for the gears, I started the reassembly and then had to wait a few hours again for the epoxy to set on the end sleeves. So, it takes some time and patience. Initially, the job was a little intimidating but after spending time with it - it wasn't too bad. Maybe it would have been easier had I removed the bottom seat cushion. I just noticed that the directions said to do that. :)
