Question:
On my 2007 Suzuki Grand Vitara the bolts that need to be removed for the install are rusted on and I am unable to remove them is there a cheap option that could be used? Any help would be thankful.

The Curt Trailer Hitch Receiver # C12002 for your 2007 Suzuki Grand Vitara uses weld nuts on the inside of the frame rails to attach the bolts and mount this hitch. If there are currently bolts in that location, you will need to remove them and there are a couple of routes to go about doing so.
First, I recommend using the UltraLube Biobased Spray Lubricant and Penetrant to get into the small crevices to free up the bolt from the nut as dirt and corrosion can cause a bolt to cease up and not want to cooperate. Some of this oil along with some vibration from tapping on the bolt will help. You may need to do this over the coarse of 15-20 minutes to allow the oil to work. If you are not able to free the bolt after that, the best option is to have a shop apply heat with a torch to the bolt and then they can then remove it.
Once a bolt is out, I recommend using the penetrating oil and a brush like # 814092 to clean the weld nuts. I've attached an article to assist.
