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.

    Happy with my purchase.

    The part was as described. It was made of quality material and was the perfect fit. It even arrived sooner than expected. The only thing missing was a picture of the kit to give us reassurance we were ordering the right product. But no worries, it was the right part.

    Great product. Documentation could be improved.

    Posted by Nick on 23rd Jun 2022

    My driver's seat stopped moving forward/backwards after 230,000 miles and 15 years on my 2007 Suburban and I looked to the forums for solutions. I was planning to go buy a junkyard seat, but then found a link this kit on a forum. This kit solves a niche problem: GM's low quality plastic gears that break inside their seat forward/backward adjustment. The gears are great quality and fit in perfectly with the other parts. $70 seemed pricey at first for 4 pieces of metal, but it solves a problem that would otherwise require an entirely new seat unit, so this kit is well worth the price. Thank you Paul for designing these-- I'm sure you've saved many people huge amounts of money by avoiding buying an entire replacement seat unit. However, given this premium price, it would be nice to have better documentation. The video and the printed instructions are both missing small steps. Not a huge deal, and I eventually figured everything out, but I had to go back and forth between both the written instructions and video at the same time to understand exactly what to do. Had the instruction set been complete, I could have likely completed this repair in an hour less time. Paul, if you ever happen to do this repair again, I'd love to see a new, more detailed video. Thank you!

    Gruven products are incredible. I can buy a $70 part and fix what the dealer would charge $800. I have fixed both seats up/down and forward/aft. The instructions are so simple to follow a dumb kid from Jersey can follow them. Thank you Gruven!

    Easy to install & worked GREAT

    Posted by Danny on 8th Mar 2022

    The new gears were a perfect fit and work like new. I don't think I will have this problem again.GM should start using these in all their vehicles, but I guess that would cut down on replacement part profits.

    GM junk plastic part replaced with quality material

    Posted by Unknown on 18th Oct 2021

    100% better than the GM OEM part! The brass will likely outlast the vehicle and the website gives you the link to the "how to" video that was exactly what had to be done to install the part! -- Response -- Thanks for review. Yes these repair the seat height and please also note now we have the seat fwd/back gears too. Its not a bad idea to just replace all the plastic gears in these power seats at the same time.

    Fixed my seat and saved me hundreds of dollars

    Posted by Mike on 11th Oct 2021

    This is a nice kit to replace the gears in the FWD/AFT motion drive. I installed it on a 2007 Escalade drivers seat. I found the video and ordered the kit. I watched the video again when the kit arrived. The video did not prepare me for the job thou, there’s more steps required than the video shows, be sure to read the written directions. I’m an Aircraft Mechanic so it made more sense to me to use a drill bit and drill the ends of the “rivets” off the seat shaft, instead of trying to get a grinder on them. There are a couple things I thought could be improved. The ID of the gears is significantly bigger than the shafts they’re glued on, having a tighter fit at one of the radial locations would really help line things up while the glue dried. As hard as I tried, one of my gears ended up a little off. Second, the parts are thrown loose into a bag and that bag is thrown into a second bag and mailed to you. This works fine but I thought having some sort of packing would’ve been nice. Printed instructions would be nice to find in the package too. -- Response -- Thanks Mike we appreciate the honest review. I wanted to make the gear bore a bit tighter on shaft but there is variance in shaft diameter so that would result in some people having to grind down shafts to fit the gears. I also want some space for the 24 hour epoxy to layer in there. This creates a very tight bond, but yes it does need to be reasonably centered. Glad you got it working and now can move the seats fwd/back without spending big money on a costly GM base which would come with - you guessed it - more plastic gears to break. Paul@gruvenparts.com

    Great idea, well executed and documented

    Posted by Richard Guy on 3rd Oct 2021

    Great product, if I can do it, anyone can! But the install was still much harder than I expected and much harder than the video suggested. Hardest part for me was grinding off the rivets to free up the cross member which was not depicted at all in the vide. The instructions as quoted above state "Locate the front main cross member which the seat drive units are connected to. You will need to grind the rivet heads on either end of this bar such that you can slide it out of the seat structure. Do not cut into the seat bar itself, just remove the rivet head." I would say instead "Use a cutting wheel on a dremmel to cut through the terminal rivets and the bar itself so that the end of the bar is flush with the seat structure into which it sits". If the bar isn't flush with the seat structure it's impossible to easily slide it out. Also attempting to grind down the heads will take far too long - much better to just cut through them. I hope this helps someone. Oh, also, if you try and drive the car with a seat out, it will say "Service air bag" - that error goes away when you replace the seat.
