Not something I worked on tonight, because we are currently driving back to Tucson from a weekend at Joshua Tree National Park.
For 6+ weeks I've been trying to get out to the garage and drop the headliner on the 4runner to reinstall the roof rack bolt holes. Toyota uses 4 metal tabs that each have a pair of M8x1.25 threads for the bolts. They're held onto the roof panel with 4 little steel clips. Unfortunately I'm a dumbass and didn't know the bolts are glued in, so instead of using slow and steady applied force to remove them with a breaker bar, I went at it with my impact driver. The first tab got sheared off at the nylon centering insert and spun the tab around on the inside and it fell into the headliner. That was over 3 months ago. Since then I've been slowly removing the trim following the service manual to drop the headliner and reinstall some factory tabs/clips. It has been a holy PITA. I finally got it done a day before we drove to California to meet the Phoenix club, Southwest Yotas, for a 3 day/2 night trip to Joshua Tree.
The interior of the 4runner was filthy. 15 years of caked on grime. I could not in good conscience do all of that work without a thorough cleaning behind the trim. I vacuumed out decaying coins, .22 short blanks, dead bugs, rocks, old food and soda syrup...it was disgusting. I did most of this, and rebuilt the entire interior, and reinstalled the camper, the NIGHT BEFORE we took off for Cali to meet the crew at camp. I was up all night working and my wife drove me asleep the whole way. It's been a rough 4 days but I'm glad I got it done and we went on our last trip with the AZ club before we move back to Albuquerque. We take ownership of our new house in less than 3 weeks.
I now have extensive knowledge and pictures of the trim panels and sub-interior of the 4th gen 4runner and where all of the control modules are located. While in there I disconnected the window defrost heaters on the rear side windows so that they can't shatter unexpected one day. I've read about it happening to some unfortunate souls. I hope I never have to drop that headliner ever again, but could probably do it in a few days if I had to. And DAMN the Toyota electrical engineers for 1) making the cabin lights hardwired into the roof harness and 2) not including a plastic disconnect of the whole roof wiring to the main harness. It makes it unnecessarily difficult to get the headliner out once you've actually dropped it, and increases the chance you'll damage it once lowered. All they had to do was include a clip that disconnects under the driver side footwell, but no. I hope the bastard engineers that saved a few hundred dollars for the assembly line manufacturing got a fat promotion.
Edit - I also used soapy water buckets and rags to wipe down the entire metal interior and detailed the carpet and each plastic trim piece down to the gear selector. It was really satisfying but took forever. I must have poured 4 or 5 buckets of black water down the sink doing that. Will post pics from the Joshua Tree trip sometime this week.
