•    Tools Needed:  Grinder and Welder
•    This is not an easy repair.  The power seat assembly was not made to be disassembled.
 
You will need to grind two spots to disassemble and reweld for reassembly.
2006 - 2011 Buick Forward / Backward adjustment steel gear kit is good for one seat repair for Forward / Backward movement due to broken gears.  The kit comes with two steel gears mounted on two custom machined shafts and a lifetime warranty for steel gear breakage.  During installation, reuse the factory, small worm gear.
 
This kit also comes with a new front thrust washer, a small bottle of grease, as well as detailed instructions with colored photos. You will reuse your rear thrust disc and other mounting hardware.
