2010 malibu the two bolts that hold the drivers seat rail the nuts that are securing the bolts seem to have broken loose if I take the bolts out and the nut drops how do I reinstall

Due to Federal Safety regulations, the normal way for this belt to be secured to the car is by a big bolt which is fastened to the body of the car with a nut that cannot be removed. Often, the anchoring bolt is underneath the carpet, and may require quite a bit of the interior of the car on that side to be removed to gain access.
If you have a junk yard/salvage yard nearby, go there and find out what to do, because cars there should have some seats removed.
Be blessed.

For this year model, I would recommend finding a seat at a salvage yard. It will be considerably cheaper than purchasing one online (shipping) or buying a new one from the dealer (outrageous mark-up).

As for replacing it, most GM products are fairly simple to remove the seat from. I haven't replaced the seats in this particular year model, but I would start with looking for four studs running up from the floor of the car where the feet of the seat supports bolt to. It's normally or 5/8" or 3/4" nut holding the seat rails (feet) to the studs. On SOME GMs, depending on the year model, the studs are actually bolts and made need to be secured from underneath the car with a wrench to hold them still while you're removing the nuts... kind of a pain, but definetly a DIY job.

One thing... if you happen to have side-impact airbags on the car, be sure to disconnect the battery cables before removing the seats. If the airbag accidentally deploys, if can cause injury.

Good luck!

look under seat and u will ee the rails on each side of seat rock seat back and forth to locate wich bolt is loose or broken or if the rail itself is broken if rail broken remove the seat and order or go to a junkyard for the rail

on the seat rail on either side of the seat on the floor itself there are 4 bolts,2 bolts on each of the front rails(1each) and 2 on the back of the seat rails.remove these bolts and disconnect all connectors for the power seat and remove the seat assembly.

take out the rear bolts and tilt/lift the seat forward. after the wiring is disconnected it will come out.

pry off any plastic bolt covers where the bolts secure the seat
pull 4 bolts securing seat to vehicles floor pan
Disconnect negative battery teminal,
disconnect any electrical plugs going to the seat
pull out drivers door opening

Seat is on rails. Look at the back of the rails, remove those two bolts and the whole thing will then tilt up and forward and come out. If there are wires you will have to disconnect the plug.

you will have to replace the complete assy. the cheapest way is look for a complete wrecking yard seat, or have yours welded at a local machine shop

hi there should be some bolts behind the side covers of seats they maybe loose?? or are your actual tracks/rails sliding?

most cars have four bolts that hold the seats in.  Remove these and unplug the harness and you can inspect everything.
