My Celica GT came with the medium spoiler and with weak struts to support the hatch, it never stayed open. I tried changing them yesterday, but the 12 mm ball bolt is and was stuck in the hatch. The left one is in and works flawlessly, but the right one has the bolt so seized in that even an impact gun socket couldn't get it out, (tried it).
So my car currently has 1 working strut and 1 missing strut. Any idea on what to do in order to remove the old bolt or just get the new strut in?
2. Remove the 2 bolts and back door stay from the body. Do not strip the bolts by trying to unscrew them with only regular tools. For these bolts that were "impossible" to remove, I used a gas BBQ lighter [google.com] to heat up the "loctite" glue (blue) that Toyota used on the OEM trunk-shocks so it could be unscrewed from the trunk hatch.
More information on using heat to remove loctite can be found at: http://www.ehow.com/how_5201363_remove-loctite-bolts.html -- If you've never done this before, searching YouTube videos for "how to remove loctite bolt" could provide additional help.
5. Use your heat source on the remaining ballstud. I used a butane lighter for 20-30 seconds from less than half an inch away. Butane lighters are inexpensive and can be purchased from any liquor store for less than $2.00. I recommend the use of a butane lighter instead of a regular lighter because the flame of the butane is directional and can be "focused" directly on the bolt. This is important because the rubber seal of your hatch is an inch away from the bolt and is prone to damage from the heat.
6. Using your 12mm socket wrench, remove the cut ball-stud bolt:
It should twist right out now. You should see red stuff stuck in the threading on the bolt. This is the loctite that you burnt off with your heat source. When you're putting in the new bolt it will be a little difficult getting it in because there will be remaining locktite still in the threading of the trunk. Try to clear out as much of it as possible with your fingers.
I used a BBQ lighter the first time I changed mine so many years ago. It took about 15 minutes of heat, and then the bolt just slid out.
So you've already done this but now the head is completely stripped and you have nothing to grasp. correct?
There are a few different ways to precede. One is to tap the broken screw head with another screw by welding them together and then retrying back from step one again with the heat.
If you've already created too much damage, you may need to drill out your old screw and prep the area for a whole new one.
Both of these methods are probably best left to that of an autobody shop or your local mechanic/repair shop.
If anybody is still wondering, I used Harbor Frieght's left handed drill bit set, https://www.harborfreight.com/left-hand-drill-bit-set-13-pc-61686.html . I drilled the bolt out until it got went through and I screwed it out using vice grips. The base of the bolt was entirely gone, but it worked perfect.
